Dependencies not loading or partially loading

Question

I am trying to work with the MS Lync UCMA 4.0 sdk and just switched to using Visual Studio 2012 (becuase .NET 4.5 Framework is required). I can't figure out what is going on here, I've set the Target CPU to x64 and the Target Framework to .Net Framework 4.5 because I was getting the error:

"Could not load file or assembly 'SIPEPS, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified."

Now that I've made these changes I get the below error.

Server Error in '/' Application.

WRN: Partial binding information was supplied for an assembly:
WRN: Assembly Name: Azure | Domain ID: 2
WRN: A partial bind occurs when only part of the assembly display name is provided.

Answer 1

I had a very similar problem. I found the problem was that it couldn't find the dependency, and I was able to find out which one by using a dependency walker. Link

You can open your .exe here, and it'll point out what you're missing in your project. For me it was the Microsoft C++ redist.

Answer 2

I had a similar issue after I copied my test code from my local machine to the trusted application server. I had to remove the Microsoft.Rtc.Collaboration dll reference from the project and browsed it in the application server and re-linked it.
