If you're using EF 4.4.0.0 then the assemblies aren't in the bin folder, we can't tell you why, ensure you are referencing them correctly.

If you're using EF but a different version then something in your project is using that version. Either find out what and fix it, or (especially if it's not your code that is referencing it) add a version redirect and redirect 4.4.0.0 to the version you are using.

hi,

First: you should not remove the version.

Do you use NUGET to add EF to your project? have you updated EF recently? may be the EF version is updated and some where in your project the old vesion is addressed in your configs
