Large Model Problems Continue to Plague Entity Framework, NHibernate
Entity Framework continues to have performance problems when using larger EDMX models to generate classes. “If the EDMX only has one entity type materialization takes 840 ms […] but when the EDMX contains a richer model, for example one with 67 entity types and 92 associations, the same test takes 7246 ms to complete”.

Actors Made Easy with C# and TPL DataFlow
For some design problems actors can make all the difference. An Actor is an independent entity that can respond to and send messages. In a way it is like its own little program running inside another process. But building actors in languages that don’t natively support them can be difficult, but Johan Olsson found a way to simplify the process using TPL DataFlow.

An Interview with Greg Finzer of Compare .NET Objects
Writing code to compare objects can be tedious, especially when dealing with large objects or deep graphs. And when the classes change errors often slip in. One way to reduce the potential for error is to rely on a library such as Greg Finzer’s Compare .NET Objects. This library offer reasonable performance for up to 10,000 objects.

Introducing Rodney Viana’s WinDbg Extension for .NET Debugging
When a .NET application fails in production the developer is often left with just a memory dump. Since Visual Studio cannot handle dumps, you have to instead look at a tool called WinDbg. Though powerful, these can be difficult to use so developers occasionally create their own extensions. Once such developer is Rodney Viana, who has just released netext 1.6.1 as an open source project.

Implementing With Domain-Driven Design from the Ground Up
The domain describes your business and in Domain Driven Design, (DDD), the domain is the most important ingredient of the application, Andras Nemes explains when starting a series of blog posts on building a web service based on Domain-Driven Design principles. His goal is not to cover all details and aspects of DDD, his ambition though is that also developers completely new to DDD can benefit.

Enterprise Developers Stuck on .NET 4.0
Whenever a new version of the CLR is released, such as .NET 2.0 and 4.0, developers are understandably reluctant to upgrade. CLR updates bring subtle changes to the runtime behavior that can break pre-existing code. But when it comes to .NET 4.5’s library-only release, the problem comes down to operating systems.
