Here are my open source projects hosted on CodePlex:
Entity Framework Interface Generator
This project contains customized T4 templates which can generate interfaces and attributes for the DbContext class and entity classes.
Entity Framework 5.0 View Generator
It contains a single T4 file which is a clone of ASP.NET Web Forms Application Using Entity Framework 4.0 Database First. The T4 template also contains fixes to work with .NET 4.5 regarding the following error: Argument 'xmlReaders' is not valid.
This project has one class Uri.cs which allows combining multiple parts to make a safe (encoded) Uri.
I extracted the setup file and uploaded it to this project for easy access.
