I hear that breaking things is the best way to learn new concepts.

Anyhu, while working with SQLServerCompact, I had this issue
Could not load file or assembly 'System.Data.SqlServerCe.Entity, Version=4.0.0.1, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference.

I wasnt sure what the issue exactly was and then realized that there was a dependency line in my web.config refereing to this assembly

 

       

       

     

I removed this dependent assembly and my scaffolded control works likea charm now..
