Entity Framework: Anti-Patterns To Avoid In N-Tier Applications

Microsoft ADO.Net team released (this month June 2009) a set of features that build on top of Entity Framework 4.0 Beta 1
The features included in this CTP are :

1.Templates for Self-Tracking Entities (N-Tier support)
2.Templates for POCO (Plain Old CLR Objects) Entities
3.Code-Only Programming Model that allows you to write Entity Data Model based applications without requiring external artifacts

While working with Entity Framework v1 during KiGG implementation of Entity Framework repositories, I decided to test KiGG for partial trust environment. Particularly Medium Trust support. Will not go through whether KiGG currently support medium trust or not in it current or upcoming version, but I will go through one of the reasons why KiGG currently might not support medium trust. It is because MY implementation of Entity Framework. Note that I am saying MY, because Entity Framework application can run on medium trust.

I'll explain in this article why memory leaks exist in .NET and how to avoid them. Don't worry, I won't focus here on the inner workings of the garbage collector and other advanced characteristics of memory and resources management in .NET.

It's important to understand leaks and how to avoid them, especially since they are not the kind of things that is easy to detect automatically. Unit tests won't help here. And when your application crashes in production, you'll be in a rush looking for solutions. So, relax and take the time to learn more about this subject before it's too late.

Multicore processors are now ubiquitous on mainstream desktop computers, but applications that use their full potential are still difficult to write. Version 4 of the .NET Framework will deliver several tools that programmers can employ to make this task easier. This article explores the use of one of those tools: Parallel LINQ (PLINQ).Igor OstrovskyMSDN Magazine December 2009
