I need to implement 3 public methods that all rely on the same initial join. Would a solution like the one described below work? The code below is an example, the real stuff is much more complicated, that's why I want to reuse it. private Tuple<Customer,Order> GetCustomerOrders() { from c in customers join o in orders o...
In my database there's a datetime column "Created" with default value getutcdate(). I would like my EF datacontext to generate an insert query that doesn't set this column, and fetch the resulting value. Is there a way to do this?

I want to learn to use Fluent NHibernate, and I'm working in VS2010 Beta2, compiling against .NET 4, but I'm experiencing some problems. Summary My main problem (at the moment) is that the namespace FluentNHibernate isn't available even though I've imported all the .dll assemblies mentioned in this guide. This is what I've done: 1.

Do Silverlight 4 applications require that they target .NET 4. With the delay in .NET 4 and Visual Studio 2010; can I still get the advantages of Silverlight 4 running against the .NET 3.5 framework? ...
A useful convenience introduced in .NET 4 is Stream.CopyTo(Stream[, Int32]) which reads the content from the current stream and writes it to another stream. This obviates the need for slightly tedious code such as this: public static void CopyStream(Stream input, Stream output) { byte[] buffer = new byte[32768]; while (true) ...

I have a small C# library written in C# (and .NET4.0 B2). I use a resource assembly (let's call this XXXAssembly) containing resx files to provide the message strings which are used in other assemblies.

I was thinking about how Regex.Match.Group wants to be dynamic: Regex.Match (...).Groups["Foo"] would like to be: Regex.Match (...).Groups.Foo I thought about writing an extension method that would allow: Regex.Match (...).Groups().Foo And tried writing it this way, but this isn't allowed (';' required by 'static dynamic') pu...
The Managed Extensibility Framework is both a stand-alone project (currently targetting .NET 3.5) and part of the .NET 4.0 framework. Suppose I create assemblies targetting .NET 3.5 that contain MEF parts. These assemblies will reference the stand-alone version of System.ComponentModel.Composition.dll. Now suppose I create a MEF-enabl...
I just heard about BDD when I watch video of Scott Guthrie in Sweden. One of listener asked question to Scott about How VS2010 and ASP.NET MVC do to support BDD. After that, I search about BDD (Behavior Driven Development) that focus on specification more than unit testing when compares with TDD (Test Driven Development). I found some f...
