Get logging in Windows Azure with Enterprise Library

tomholl — Mon, 06 Sep 2010 14:42:00 GMT

Hi again – yes I know it’s been a while. Recently I’ve started a new role in Microsoft which involves helping customers deploy applications on Windows Azure, Microsoft’s cloud computing platform. I thought it may be fitting it I kick this off with a post that bridges my (now quite) old role with my new one and talk about using Enterprise Library with Windows Azure.

One of the great things about Windows Azure is that it includes the .NET Framework in its entirety – so for the most part, .NET code you’ve written in the past will run fine in the cloud. However there are some important differences between your own servers and the cloud that you need to be aware of as a developer or designer. For example, while it is technically still possible to log to a flat file or the Windows Event Log, it’s generally impractical to access the resulting logs. As a result, logging and instrumentation is one of those things which you need to do a little differently in the cloud.

Using Windows Azure Diagnostics

It so happens that Windows Azure includes its own diagnostics infrastructure. It’s well documented elsewhere (try the official documentation or this MSDN Magazine article) but in a nutshell it involves high-performance buffers built on ETW which collect log events from your application. These events, along with other diagnostic sources such as event logs and performance counters, can be transferred to Windows Azure Storage (tables and blobs) either at predefined intervals or on-demand.

The most commonly described approach to logging to Windows Azure Logs is to use the standard System.Diagnostics Trace class as follows:

Trace.TraceInformation("Trace works fine, but you're somewhat limited...");

Next, you’ll need to configure System.Diagnostics to log to Windows Azure Diagnostics via the DiagnosticMonitorTraceListener:

<system.diagnostics>
  <trace autoflush="true">
    <listeners>
      <add type="Microsoft.WindowsAzure.Diagnostics.DiagnosticMonitorTraceListener, 
          Microsoft.WindowsAzure.Diagnostics, Version=1.0.0.0, Culture=neutral, 
          PublicKeyToken=31bf3856ad364e35" name="AzureDiagnostics" />
    </listeners>
  </trace>
</system.diagnostics>

Finally, you’ll need to configure and start Windows Azure Diagnostics. In this example, let’s ask it to transfer all logs to Windows Azure Storage (specifically, the WADLogsTable table) every 5 minutes by modifying the WebRole or WorkerRole class as follows:

public override bool OnStart()
{
    StartDiagnostics();
    RoleEnvironment.Changing += RoleEnvironmentChanging;
    return base.OnStart();
}

private void StartDiagnostics()
{
    // Get default initial configuration.
    var config = DiagnosticMonitor.GetDefaultInitialConfiguration();

    config.Logs.ScheduledTransferLogLevelFilter = LogLevel.Undefined;
    config.Logs.ScheduledTransferPeriod = TimeSpan.FromMinutes(5);

    // Start the diagnostic monitor with the modified configuration.
    DiagnosticMonitor.Start("DiagnosticsConnectionString", config);
}

Of course, you’ll also need to make sure you define a connection to your Windows Azure Storage account in your ServiceConfiguration.cscfg file.

Bringing in the Logging Application Block

There’s nothing wrong with any of the above code, but if you’re used to using Enterprise Library’s Logging Application Block for your logging needs, you’ll soon find that you’re somewhat limited. For example, you won’t automatically get access to things like the Process ID and machine name, you won’t get the ability to customise your message format and you won’t get the advanced routing and filtering options. The great news is that since the Logging Application Block is built on System.Diagnostics, you can use it in your cloud applications and configure it to write to Windows Azure logs.

First, let’s look at your logging code. There’s nothing special you need to do here and any existing EntLib logging code should work– since the Logging Application Block’s API is abstracted from the chosen logging mechanism you just log like you always did, either using the old school Logger facade or the new fangled DI alternatives. Make sure you choose an appropriate Severity level, as both Enterprise Library and Windows Azure Diagnostics can be configured to use this to filter messages or decide which ones to transfer to storage.

Logger.Write("Get Logging in Windows Azure with Enterprise Library!", 
    "General", 1, 0, System.Diagnostics.TraceEventType.Information);

Now, let’s look at your configuration file. You can delete the <system.diagnostics> section we described earlier and use Enterprise Library’s configuration instead. You can use either the config tool or an XML editor to edit the config, but the important thing is to choose a System.Diagnostics Trace Listener and configure it to use the same DiagnosticMonitorTraceListener we used before. I’ve included just the <listeners> section of the Logging Application Block’s configuration below; in your app you can continue to use whatever combination of sources, formatters, filters and listeners you like.

<listeners>
  <add listenerDataType="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.SystemDiagnosticsTraceListenerData, Microsoft.Practices.EnterpriseLibrary.Logging, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
    type="Microsoft.WindowsAzure.Diagnostics.DiagnosticMonitorTraceListener, Microsoft.WindowsAzure.Diagnostics, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
    name="Azure Diagnostics Trace Listener" />
</listeners>

Finally, you’ll still need to configure and start the Diagnostic Monitor when your role starts. The code in the first example will continue to do the trick (although keep in mind you may prefer to configure it differently by applying log transfer filters or choosing to transfer logs to storage only on-demand).

You should now be ready to deploy your application to the cloud and see it in action. Remember, with Windows Azure Diagnostics, the log events will only be transferred to Windows Azure Storage after the specified interval or on-demand (requiring additional code or Powershell scripts), so you may need to be more patient than you’re used to. Once the transfer is complete, you should see the events in your WADLogsTable table. The easiest way to view the data in the table is to use Visual Studio 2010’s Server Explorer, but there are many other web- and Windows-based tools that can do the same and more. The data in the log files will have a little bit of XML padding, but you’ll see your formatted data sitting proudly in the middle:

<TraceSource>General</TraceSource>
<Object>Timestamp: 9/6/2010 5:05:38 AM
Message: Get Logging in Windows Azure with Enterprise Library
Category: General
Priority: 1
EventId: 0
Severity: Information
Title:
Machine: RD00155D3134BD
App Domain: /LM/W3SVC/1273337584/ROOT-1-129282230874485863
ProcessId: 1724
Process Name: d:\windows\system32\inetsrv\w3wp.exe
Thread Name: 
Win32 ThreadId:2560
Extended Properties: </Object>

To summarise, while Windows Azure does require you to do a few things a little differently, most of your existing code and favourite techniques should still work fine. With just a small configuration change and some startup code, your Enterprise Library Logging code will feel right at home in the cloud.

SQL Azure Migration Wizard v3.3.6

wcamb — Mon, 06 Sep 2010 15:00:00 GMT

Olá pessoal, tudo certo?

Esses últimos dias tenho estado bem enrolado com a preparação das demos e sessões do Tech-Ed Brasil 2010. O evento está chegando.

Um de minhas sessões é sobre o SQL Azure, falando de questões sobre administração, operação, conectividade e migração. Enquanto olhava a demo de migração, vi que o SQLAzureMW foi atualizado no final de agosto, com a nova versão 3.3.6, veja:

SQL Azure Migration Wizard v3.3.6
Ref. : http://sqlazuremw.codeplex.com/

Para quem não conhece SQLAzureMW, vale destacar que ela não é suportada pela Microsoft, porém, é muito interessante como ferramenta de apoio para testes e desenvolvimento.

A ferramenta ofere uma análise de compatibilidade dos objetos SQL Server para o SQL Azure, assim como retry/chunking durante a migração. Outro destaque é que trabalha muito bem com scrips batch, sendo por isso muito interessante para testes.

Como pontos negativos, o processo de carga é feito através de um arquivo BCP que é armazenado localmente, fique atento! Ainda, o TSQL Parser é incompleto, mas tem evoluído de versão em versão.

Guardadas as ressalvas, é uma ferramenta interessante para quem está desenvolvendo para o SQL Azure!

Por enquanto é só! Até o próximo post :)

Waldemir.

Interesting Links 6 September 2010

Alfred Thompson — Mon, 06 Sep 2010 13:08:00 GMT

Happy Labor Day! Well here in the US anyway. Technically a public/work holiday and I do plan to spend most of it relaxing. Unless my wife has other plans that is. I spent yesterday doing some early fall yard work for example. But it looks good so it was worth it. I have spent some time collecting some of the more interesting links and bits of information I saw over the last week though. You can follow me on Twitter (@AlfredTwo) and see a lot of this sort of thing as I find it during the week. Also some conversation/chat with other interesting people about educational technology and other topics. Hope to see you on Twitter sometime.

Starting with a couple of community outreach pieces of news. One is that Microsoft has become a major sponsor of National Day of GiveCamp (on Twitter @GiveCamp) Give Camp is a weekend event where volunteer tech people from various companies get together to build tech solutions for non profits. Think of it as a computer age barn raising. Previous events have already helps a good number of organizations.

Also for nonprofits: Microsoft has launched its Elevate America grants program.

[…] the Elevate America community initiative, a new grant program that will support nonprofit organizations offering employment services, including technology skills training and job placement, in local communities across the United States. To support this initiative, we are committing $4 million in cash, $6 million in software and technology skills training curriculum over the next two years.

ITA Software is helping with a Massachusetts based Aspirations in Computing Award for high school women. See the MACAA Facebook page and follow @ncwitMACAA for more information.

Some interesting news on the Kodu front this week. The @koduteam announced that they have published an official Kodu language grammar. Very cool way to start understanding both what a language grammar looks like and what it specifically looks like for a graphical language like Kodu.

Kodu is also now available in German. Kodu in deutscher Sprache

Speaking of languages, there is now a Tutorial de Scratch en español / Scratch Tutorial (in Spanish). And apparently some are using Scratch to blend old and new by having students work with senior citizens.

Speaking of MIT, Scratch and that article above both relate to MIT, a bunch of people tweeted a link to the MIT Guide to Hacking

Sam Stokes writes about Adding shapes to your Windows Phone using some simple XAML and C# code.

See how a student aced his advanced programming course and got a game released for Xbox using XNA and Creators Club BCIT student creates Xbox game.

Most people use spreadsheets for real number, integers but fractions? How to work with fractions in Excel.

From XRDS (@XRDS_ACM) – the ACM magazine for students a comparison between Punch cards v. Java.

Last week on Twitter @compsciwoman announced a new blog called CompSci Woman and a post titled a minor in CompSci makes you surprisingly employable! Now isn’t that the truth!

Have you heard about the new Clorox grant program? You can win n up to $50,000 for your favorite school. You can play daily. Called Power a Bright Future. Some school is going to win.

Last link for the day Blue-sky thinking on Kinect and Xbox in education Some interesting thoughts from Anthony Salcito, Vice President, Worldwide Education, at Microsoft.

Are routerless datacenters in Microsoft's future?

bartvagh — Mon, 06 Sep 2010 13:16:20 GMT

Microsoft Research is exploring a new way to connect servers directly to other servers, without the use of any switches or dedicated networking inside a datacenter container.

That project, known as CamCube, is one way that Microsoft execs are attempting to rethink the datacenter. More on that in a moment….

In the nearer term, Microsoft’s various development teams are making their own tweaks to the fabric powering the company’s existing and future cloud services.

Microsoft execs don’t talk a lot publicly about the infrastructure that underlies its cloud platform. Global Foundation Services runs the “guts” of the cloud, and is responsible for tweaking the datacenter servers and services that power the customer-facing Microsoft cloud components, like Windows Live, Bing, Business Productivity Online Services, etc. GFS is the team that does a lot of the work to bring online new Microsoft datacenters, like the latest one in Boydton, Virg., that the Softies just announced they’ll be building.

Extra Events for Excel

cobold — Mon, 06 Sep 2010 11:37:58 GMT

As a developer of Automation solutions for Microsoft Office one might feel the need of some extra events. Quoting from the MSDN VBA Object Model reference, here is the list of events from the Excel.Application object:

What if these events are not enough?

The best solution would obviously be if Microsoft extended the Object Model so as to include the needed events. This is pretty hard due to the large number of the possible application events (think for instance about the event “Sheet After Follow Hyperlink Success” – imaginary event triggered when a hyperlink has been clicked and the target web site can be reached)

My solution is to use Windows hooks [link to SetWindowsHookEx]. The idea is that many actions are triggered by Windows messages sent to or by windows in Office applications. I couldn’t find any public reference of the way Office applications react to windows messages but we can see this using the tool Spy++ that gets installed together with Visual Studio. Side note: the following blog post from the designer of Spy++ offers some insights about how the tool was built.

The most obvious message that can be tapped is the WM_ENABLE message sent received when a window gets enabled or disabled when a modal dialog is shown. This is not particular to Office applications, other applications have the same behavior (e.g. Notepad).

My first attempt was to intercept this message in VBA by basically adding a hook that calls a VBA function when a message is received. The problems with this approach are:

Kingston University starts virtualising the desktop experience for 25,000 students and staff

Ray Fleming — Mon, 06 Sep 2010 11:39:00 GMT

I’ve just been reading a press release from Quest, about Kingston University’s project to to give staff and students virtual access to their university desktop and learning resources from any location, on a wide range of devices, at any time. With 23,000 students, and 2,000 full-time staff to serve, their project is aiming to create a ‘university without walls’, so that their users can access their files and applications from any of the 9,000 university PCs or from users’ own personal computers – wherever they are.

What caught my eye was this quote from Daniel Bolton, who’s a technical analyst at the University:


	Kingston University has been researching Virtual Desktop Infrastructure (VDI) solutions for two-and-a-half years with the aim of providing our staff and students the best solution for flexible access to learning resources regardless of their location. Our aim of achieving a ‘university without walls’ when it comes to flexible virtual access has been truly recognised with Quest vWorkspace. We initially looked into Citrix and VMware solutions, but felt that Quest’s user environment management and personalization features were more advanced.

The whole solution has been deployed on Hyper-V, which is part of Windows Server 2008 R2, and is now the largest planned deployment for both Quest and Microsoft to date. Phase one of implementation is due to complete in October.

You can read the full release on Quest’s website. I’ll keep an eye out for updates as the project goes into implementation.

The missing toolset for SharePoint 2010 development

Markus Heiliger — Mon, 06 Sep 2010 12:06:36 GMT

For those of you, looking for a valuable VS2010 add-on for SharePoint development check out the:

CKS: Development Tools Edition at http://cksdev.codeplex.com

There are a lot of features inside the add-on, but my favorite one is the “Copy to GAC/BIN” context menu item. If you used WSPBuilder under VS2008 you will also miss this little nifty copy function from the context menu since you moved to the native SharePoint project type under VS2010 – right !?! So, here is your way out!

PHP 5.3 and IIS 7 - beware of MySQL issues with IPv6

James Crowley — Mon, 06 Sep 2010 11:02:00 GMT

I'll keep this short and sweet as it's covered in depth elsewhere. After installing PHP 5.3 suddenly my website stopped working - but instead of throwing errors, it simply sat there and eventually timed out (with no error). Turns out there are issues with both PHP and MySQL around IPv6. The most common solution is "turn off IPv6 support" - not a reassuring answer.

On the PHP front, the issue seems to be around fsockopen which works fine in 5.3.0 but not in 5.3.2. The major issue for most people though is that the MySQL driver doesn't properly support IPv6 if you're using a hostname (such as localhost) to connect instead of an IP address, particularly when localhost resolves to "::1".

I'm not sure what changed in PHP 5.3.2 to bring this to the surface, but the solution is either to switch to using an IP address, for which there are other good reasons to do so, or modify your hosts file (c:\windows\system32\drivers\etc) and change the line the starts with "::1 localhost" to "#::1 localhost".

Hope this helps someone!

An authentication error occurred while communicating with the web server

Carlo Cardella — Mon, 06 Sep 2010 10:31:00 GMT

Dopo l’installazione della Service Pack 2 di .NET 2.0 (o della SP1 di .NET 3.5) tentando il debugging remoto di un’applicazione web per la quale utilizzare gli host headers, potreste incappare in questo errore:

Unable to start debugging on the web server. An authentication error occurred while communicating with the web server

Il motivo è una modifica di sicurezza introdotta proprio da queste Service Pack: il comportamento di default è ora quello di utilizzare l’host name specificato nell’URL, in un SPN nel pacchetto di autenticazione NTLM; in altre parole facendo una richiesta all’indirizzo http://myserver/myapp, l’SPN “HTTP/myserver” viene aggiunto alle informazioni di autenticazione. Questa è una buona cosa dal punto di vista della sicurezza, ma con alcune conseguenze sgradite…

Il processo di autenticazione NTLM prevede un meccanismo di challenge che parte dalla macchina di destinazione (il server web) ed ha come destinatario il client che ha fatto la richiesta iniziale; quando Windows riceve un challenge che lui stesso ha generato, l’autenticazione fallisce a meno che la connessione non sia di tipo loopback. Quando un sito ha un host header configurato, l’host name non è ne il nome della macchia, ne l’indirizzo IP di loop back, ne l’indirizzo IP della macchia, quindi l’autenticazione è destinata a fallire.

Esistono due possibili soluzioni a questo problema:

L’approccio raccomandato consiste nel mappare l’host header con il look pack address nel registro di sistema, ecco come fare:
- Cliccate su Start > Run, digitate regedit e cliccate OK
- Nell’editor del registro di sistema selezionate la chiave “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0”
- Create un nuovo valore di tipo Multi-String e chiamatelo BackConnectionHostNames
- Modificatene il valore digitando l’host name (potete inserire anche più di un nome) del sito o dei siti che si trovano sul server
- Riavviate IIS
La seconda soluzione, però meno sicura della precedente, consiste nel disabilitare il loop back check come descritto in http://support.microsoft.com/kb/896861

Вычисление декартового произведения с помощью LINQ

Русский MSDN — Mon, 06 Sep 2010 11:00:00 GMT

Вот еще одно сообщение, основанное на очередном вопросе со StackOverflow: как вычислить декартово произведение произвольного количества последовательностей с помощью LINQ?

Прежде всего, давайте удостоверимся, что мы понимаем, о чем идет речь. Я буду обозначать последовательность как упорядоченное множество {a, b, c, d, ...}. Декартово произведение двух последовательностей S1 и S2 представляет собой последовательность со всеми возможными вариантами последовательностей из двух элементов, в которых первый элемент берется из S1, а второй – из S2. Так, например, для последовательностей {a, b} и {x, y, z} декартовым произведением является последовательность, состоящая из двухэлементных последовательностей: {{a, x}, {a, y}, {a, z}, {b, x}, {b, y}, {b, z}}.

Ради упрощения, давайте предположим, что S1 и S2 представляют собой последовательности элементов одного типа. Конечно мы можем найти декартово произведение последовательности строк с последовательностью целых чисел, как последовательность кортежей (string, int), но этот вариант будет весьма сложно обобщить, поскольку система обобщенных типов языка C# не очень здорово работает с кортежами произвольной длины.

В LINQ содержится оператор, предназначенный для декартового произведения: с помощью синтаксиса на основе вызова метода (fluent syntax) – это SelectMany, а с помощью «языка запросов» - это запрос с двумя операторами “from”:

var s1 = new[] {a, b}; 
var s2 = new[] {x, y, z}; 
var product =  
  from first in s1 
  from second in s2 
  select new[] { first, second };

Конечно, мы можем обобщить декартово произведение более чем на две последовательности. Декартово произведение n последовательностей {S1, S2, ..., Sn} представляет собой последовательность, которая содержит набор всех возможных последовательностей из n элементов, в которой первый элемент берется из последовательности S1, второй – из S2, и т.д.

В этом определении не учитывается примитивный случай. Чему равняется декартово произведение пустых последовательностей? Давайте обозначим результат декартового произведения одной пустой последовательности следующим образом: { { } }. (См. комментарии для обоснования того, почему это хорошая мысль; изначально я думал использовать пустую последовательность { }, но этот способ лучше. Спасибо Apollonius за отличный совет.)

Обратите внимание, что это приводит нас к разумному определению декартового произведения одной последовательности. Декартово произведение последовательности, содержащей в качестве элемента одну последовательность, скажем { {a, b} }, является последовательность всех возможных последовательностей, состоящих из одного элемента, в которых первым (и единственным) элементом является {a, b}. Т.е. декартовым произведением последовательности { {a, b} } является { {a}, {b} }.

С помощью LINQ вы можете очень легко выполнить декартово произведение любого количества последовательностей, но для этого вы должны знать количество последовательностей.

var product =  
  from first in s1 
  from second in s2 
  from third in s3 
  select new[] {first, second, third};

А что если вы не знаете количество последовательностей в момент компиляции? Т.е. как вы сможете реализовать тело этого метода:

public static IEnumerable<IEnumerable<T>> CartesianProduct<T>(this IEnumerable<IEnumerable<T>> sequences)

Ну что ж, давайте рассуждать методом индукции, что всегда является отличной идеей при работе над рекурсивными структурами данных.

Если последовательность содержит нулевое количество последовательностей, мы справились; мы просто возвращаем { { } }.

Давайте снова вернемся к тому, как мы вычисляем декартово произведение двух последовательностей, скажем {a, b} и {x, y, z}. Мы начнем с вычисления декартового произведения первой последовательности. Давайте сделаем гипотетическое предположение, что мы знаем, как это сделать и в результате мы получили { {a}, {b} }. Как объединить { {a}, {b} } с {x, y, z} для получения необходимого декартового произведения?

Итак, давайте ради вдохновения вернемся к нашему исходному определению декартового произведения двух последовательностей. Декартового произведение { {a}, {b} } и {x, y, z} – это последовательность вида {{{a}, x}, {{a}, y}, {{a}, z}, {{b}, x}, {{b}, y}, {{b} ,z}}, что очень похоже на то, что мы хотим получить в результате. Но мы не только хотим вычислить декартово произведение {{a}, {b}} и {x, y, z} путем создания последовательности, которая будет содержать {a} и x, мы хотим вычислить декартово произведение путем добавления x к последовательности {a}, для получения {a, x}! Или, иначе говоря, путем конкатенации {a} с {x}.

Вернемся к коду. Предположим у нас есть старое декартово произведение, скажем { {a}, {b} }. Мы хотим объединить его с последовательностью {x, y, z}:

var newProduct =  
  from old in oldProduct 
  from item in sequence 
  select old.Concat(new[]{item}};

И теперь мы получаем полноценный рекурсивный случай. Если oldProduct представляет собой любое декартово произведение, тогда мы можем вычислить новое объединение этого произведения с другой последовательностью для создания нового декартового произведения.

Просто ради проверки: учитывает ли этот вариант наш базовый случай? Да. Если мы хотим вычислить декартово произведение { { } } с {a, b} тогда мы объединяем { } с {a} и { } с {b} и получаем { {a}, {b} }.

Давайте соберем все это в одном месте:

static IEnumerable<IEnumerable<T>> CartesianProduct<T>(this IEnumerable<IEnumerable<T>> sequences) 
{ 
  // базовый случай:
  IEnumerable<IEnumerable<T>> result = new[] { Enumerable.Empty<T>() }; 
  foreach(var sequence in sequences) 
  { 
    var s = sequence; // не замыкаем на переменную цикла    // рекурсивный случай: используем SelectMany для создания нового произведения на основе исходного произведения
    result =  
      from seq in result 
      from item in s 
      select seq.Concat(new[] {item}); 
  } 
  return result; 
}

Вариант хороший, но если нужно, мы можем действовать чуточку хитрее. На самом деле мы используем аккумулятор (accumulator). Давайте рассмотрим простой случай, скажем, добавление суммы к списку целых чисел. Одно из решений состоит в следующем: «накопить все значения, начиная с нулевого. Новый аккумулятор вычисляется на основе старого, путем добавления текущего элемента к предыдущему значению». Если мы начинаем с некоторого значения аккумулятора и некоторым способом создаем новое значение аккумулятора по предыдущему значению и текущему значению элемента последовательности, тогда, в этом случае мы можем воспользоваться удобным методом расширения с именем Aggregate. Он принимает начальное значение аккумулятора и функцию, которая принимает последнее значение и текущий элемент и возвращает следующее значение аккумулятора. Результатом выполнения этого метода является окончательное значение аккумулятора.

В таком случае начальным значением аккумулятора будет пустое произведение, и на каждом шаге мы будем «добавлять» к нему сумму текущей последовательности и полученного произведения. На каждом шаге аккумулятор будет содержать декартово произведение всей последовательности пройденной до этого шага.

static IEnumerable<IEnumerable<T>> CartesianProduct<T>(this IEnumerable<IEnumerable<T>> sequences) 
{ 
  IEnumerable<IEnumerable<T>> emptyProduct = new[] { Enumerable.Empty<T>() }; 
  return sequences.Aggregate( 
    emptyProduct, 
    (accumulator, sequence) =>  
      from accseq in accumulator  
      from item in sequence  
      select accseq.Concat(new[] {item}));                
}

А теперь тонкий момент. Помните, что результатом LINQ запроса является запрос, который выдает результат по требованию, но не выдает результат запроса сразу же. Когда мы создаем аккумулятор, мы на самом деле не вычисляем декартово произведение. Мы создаем большой и сложный запрос, который при его выполнении возвращает декартово произведение. Сам запрос строится сразу же, но выполняется отложенно.

Разумно?
