Schema specified is not valid - Exception

Question

Schema specified is not valid. Errors: (0,0) : error 0004: Could not load file or assembly 'JIMSDAL, Version=6.0.5126.47, Culture=neutral, PublicKeyToken=9054b539c49e6e2e' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Why I get this exception, I checked every dependent project of JIMSDAL and they are referencing the correct updated version 6.0.1.0.

I also checked with fuslogvw.exe and its not helping. It says

The operation failed.
Bind result: hr = 0x80131040. No description available.

There is no config file with this version too. I even removed the reference of this project and re added. But nothing works. Where am I going wrong?

Answer 1

You are referencing JIMSDAL, Version=6.0.5126.47, but the calling assembly found JIMSDAL, Version=6.0.0.0. I've had this happen in the past when mixing project references with references to a compiled assembly, but there are other ways it can happen. Look for multiple references to JIMSDAL, and make sure they are all pointing to the same thing.

This question (https://stackoverflow.com/questions/5600904/net-dll-dependency-of-same-file) describes a similar problem, you might want to take a look.

Answer 2

That's not much to go by but the FSLogVw output shows the calling assembly to be EF. Are you using and edmx? If so, you may want to open it in XML view (not design view) and see if there are references to your assembly in there. You mentioned you've already checked the .config file, so that rules that out.
