Keep an eye on what promises to be a very cool open source project!

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.
Alex James how to use T4 templates for generating entities that have regular expressions applied to them. He also continues his tips series :

David Ebbo shows how to use the buddy class mechanism (associated metadata class) that we have in Dynamic Data applications with TypeDescriptor.
He also shows a C# compiler method overload problem that we might end up with when putting methods in global namespace and having a more generic method in a namespace declared using statements inside another namespace.
David Ebbo released the 2.4 version of his cool T4MVC. Among the changes in this release:
- separate settings file called T4MVC.settings.t4 that gets included by the main file
- support for views in subfolders
- support for [ActionName] attributes
- new parameter-less overload for all actions
- support for placing T4MVC.tt below the application root

- Dependency Injection
- Unit Testing
- Object Relational Mappers
- Working with the Memory
- How to work with Exceptions

Stephen presents the Lightweight Test Automation Framework which represents an effort to improve the quality of AJAX Control Toolkit.
Scott Hanselman has a very nice post about combining and moving ScriptResource.axd to static scripts. It’ll be great if the WebResource.axd scripts will also be put in a single file and even hosted on a CDN as Scott shows!
David Ebbo continues his experiments with T4 template. He shows the option of modifying the generated code directly using the Code Model API. He uploaded a first improved version and continued with another great release.
Scott does an excellent job in promoting David’s work on MVC T4 templates.
P&P Guidance announces that EL 5.0 will focus on IoC containers for configuration offering the possibility to use other containers such as NInject, Castle Windsor or AutoFac. Check also Grigori’s announcement about the completion of the refactoring.
