How do you remove old version of entity framework

Question

Yesterday I posted a question about a issue related to entity framework version after installing MVC 4 on visual studio.

Somehow visual studio is still pointing to the old version of the dll (4.3.1.0) eventhough I manualy set it in my reference to the new one

I tried solution suggested by danielovich gacutil /u "EntityFramework, Version=4.3.1.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"

But it did not find it

No Assemblies Found Matching EntityFramework, Version=4.3.1.0, Culture=neutral, PublicKeyToken=b77a5c561934e089

If I look in my project file I can see: <Reference Include="EntityFramework, Version=4.4.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089, processorArchitecture=MSIL"> <HintPath>..\packages\EntityFramework.5.0.0\lib\net40\EntityFramework.dll</HintPath> </Reference>

Which is the new version I am trying to use. I wonder if the DLL is being referenced from somewhere else.

Answer 1

gacutil /u <fully qualified assembly name> 

Try this:

gacutil /u "EntityFramework, Version=4.3.1.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"

EF 4.+ is not designed to be GAC'ed, it's designed to be bin deployed.
