Entity Framework Scaffolding: The type is not mapped issue

Posted by Judy Alvarez Posted on February 28, 2022March 3, 2022

This was a tricky one. I was just watching Scott Hanselman’s session from MIX 11 “Microsofts Web Stack Of Love” and as always the guys it brilliant. It’s like stand-up mixed with development. Anyway, he talked a bit about MVC Scaffolding and about how awesome it was. I fired up Visual Studio and installed MVCScaffolding via NuGet added some EF Models and boom! This was what I saw.

The type was not mapped. Check that the type has not been explicitly excluded by using the Ignore method or NotMappedAttribute data annotation. Verify that the type was defined as a class, is not primitive, nested or generic, and does not inherit from EntityObject.

Hmm, that was not what I expected. Turns out that I had not installed Entity Framework 4.1 completely. I found this post and I had the same problem. Just download Entity Framework from here and everything should work as expected. Now back to the session!
