Could not load file or assembly 'MySql.Data.Entity,...

  1. I am getting the error "Could not load file or assembly 'MySql.Data.Entity, Version=6.6.5.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference."

    I wrote a little web app using visual studio web developer 2010 express. I have used the .net package manager to include the 6.6.5 MySql.Data & MySql.Web and 6.6.4 MySql.Data.Entity dll's. Configured and ran locally. What values do I need in my web.config to make it work? Or is there something magically broken with those versions, in that case what version do I need?

    Code:

  2. Ok... It turns out it was Microsoft screwing up the concept of package managers. Once selected the 6.6.5 version of MySql.Data.Entity.dll off my hard drive it works.
