In a C# application I'm Loading 2 DLLs provided by user during runtime (not a pre-difined reference) Let it be A.dll, B.dll. 
A.dll is referencing B.dll, but they are supplied separately.
When I try to access a method from A.dll, with a parameter of type that is declared in B.dll, I get an:

> 
> "Could not load file or assembly 'B, Version=1.0.0.0, Culture=neutral,
>  PublicKeyToken=null' or one of its dependencies. The system cannot
>  find the file specified.".
> 
>

error, although both DLLs were loaded. Even calling `MethodInfo.GetParameters()` will throw the exception.

Tried to Load both DLLs with different methods:

```
Assembly.Load(<Path>) 
Assembly.LoadFile(<Path>) 
Assembly.LoadFrom(<Path>)

```

I set the reference in project A to B.dll as "Copy Local = false".

Any usage of types and method from A or B which does not involve the connection described above seems to work fine. 

I made sure both assembly were loaded with 
 `AppDomain.CurrentDomain.GetAssemblies()` 
(they both are).

I have to presume I don't have developer access to A.dll and B.dll projects (provided by users), but for testing purpose I can try to change stuff in them as well.
