As a followup to the post of "malovicn":

The easiest way to prevent the FileNotFoundException is to add the t4 template by right clicking on the background of the entity designer and choose "Add Code Generation Item". If you add the t4 template by using "Add new Item" on your project, you will get the FileNotFoundException.

I think I'll stick to NHibernate...

Danny,

make sure that the line containing inputFile = ... contains a valid path to your edmx file (most probably your issue)

This doesn't work; I get the following error:

Ahh - looks like the team replaced the file online as they said they would.

And hooray. I found the EntityFrameworkTemplateFileManager difference right away but spent a lot of time trying to figure out how to deal with the WriteFiles and finally gave up. I even asked the team but got no reply. THat's why I went back to the original template. Glad you figured it out. I'll update my blog post with a pointer.
