Joe Stagner points out a DotNetSlackers project that aims to clone StackOverflow.com. In the process they will use: CruiseControl.Net, NAnt, NUnit, RhinoMocks, NDepend, NCover, NDoc, ASP.NET MVC 2.0, LINQ to SQL, StructureMap, AutoMapper, Elmah, Velocity, MemCached. Keep an eye on what promises to be a very cool open source project!

Daniel Cazzulino shows how the power of LINQ is integrated in the next version of Moq.
Simone Chiaretta dissects the DropDownList helper method.
David Hayden continues his post from yesterday showing how we can separate the validation annotations into a metadata class via BuddyMetadataProvider similar to how DynamicData works.
Daniel Cazzulino shows how to achieve strongly typed reflection for generic types and methods by creating a delegate of the target method and using the delegate’s properties to get the corresponding MethodInfo.

Jonathan Oliver has an excellent post about distributing a single bounded context on different machines and dealing with optimistic concurrency.
Julie talks about entity properties that we can take advantage of in EF 4.0 and that are designed for model first and dynamic data support.
Fredrik Normen shows how SubmitChanges mechanism works in .NET RIA Services.
Mike Taulty has a nice post about Unity’s features.
David Hayden shows how the support for System.ComponentModel.DataAnnotations in DefaultModelBinder works in ASP.NET MVC 2.0 Preview 1.

Mattieu Mezil show how to use TypeDescriptors to make FK work in EF 1.0.
In his 30th tip, Alex James shows how to use database functions in EF 1.0 and EF 4.0.
The ADO.NET team presents the improvements to the generated SQL for Entity Framework.

Kirill Osenkov points out the C# compiler team blogs.
Chris Burrows has a nice post about dynamic base classes.
Eric Lippert has another bunch of excellent articles:
Jan Van Ryswyck talks about fluent domain methods for setting up complex aggregate roots and for implementing behavior on domain entities.
Alex James also shows how to work with fluent interfaces and how to use fluent interfaces with extension methods.
Jérémie Chassaing shows how Service Bus pattern can help in DDD with code reusability.
Ayende talks about decomposing an application into features as a way for separating different application functionality and to allow independent development.
Julie Lerman shows how in EF 4.0 the function mapping feature is improved as the conceptual space also gets the function allowing it to be called from the entity directly and not through EntityClient. She also points out a bug when using T4 template instead of EntityModelCodeGenerator for CustomTool mode. Another great article is about the major improvements in EF 4.0 for working with complex types.
The Entity Framework Design team talks about the Code Only enhancements that will be available in the next release.
