CLR Inside Out: What's New in the .NET Framework 4 Base Class Library

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.

This one has cropped up a couple of times in my development activities recently, but with just enough of a gap for me to have forgotten the solution and I had to figure it out again.
