So, I know there have been a lot of questions similar to this, but I've poured through many answers over the past day and nothing has helped.
I'm developing a WPF application that is referencing a bunch of external DLLs. There is one DLL in particular, called DefinitionInterpreter, which has proven to cause trouble. In every project I reference it in, it is stubborn and chooses not to work. I was able to get it to work in my unit test suite, however, I cannot, try as I may, get it to work in my WPF application.
I have tried GAC, cleaning my project, adding it and removing it, restarting, checking the version, checking the dependencies, and nothing works.
I keep getting the same exception:
Could not load file or assembly 'DefinitionInterpreter, Version=3.6.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
I have tried opening the DLL in ildasm.exe and it didn't show anything unusual. It's only dependencies are System.Xml, System.Core, and mscorlib.
When I check the manifest, it verifies that the version is 3.6.0.0
The thing that really gets me is that it works in one of my projects, but I can't get it to work in another, even though they are referencing the same DLL (same path and everything).
Any suggestions? I am using .NET 4.0 (it is a project requirement that it is 4.0) and have tried both x86 and x64.
Edit:
After viewing Fusion Log details, I get this as output:
*** Assembly Binder Log Entry (7/18/2013 @ 7:07:42 PM) ***

The reference in my CSProj is as follows:
<Reference Include="DefinitionInterpreter, Version=3.6.0.0, Culture=neutral, PublicKeyToken=75a99a2a5bcd4c96, processorArchitecture=MSIL">
<SpecificVersion>False</SpecificVersion>
<HintPath>..\..\..\..\DefinitionInterpreter.dll</HintPath>
<Private>True</Private>
</Reference>
When I perform the command sn -T DefinitionInterpreter.dll I get 75a99a2a5bcd4c96. I'm honestly at a loss how at runtime it thinks the public key token is null and why there is a mismatch.
