Referencing a C# library from a 3-rd party application fails. Manifest doesn't help

Question

Hi,

I've been struggling with this problem for a long time now.  I've got a C# library, that uses another .NET libraries, which use unmanaged libraries.  My C# library needs to be built to a directory, where all those other libraries are built to - because of reference issues. 

A 3rd party application (EXE) attempts to load my C# library. But, it loads it from within its own base directory - which is, obviously, not appropriate and is not working.  I have no control over how that app is loading it. Maybe, the only way too fix it is to use a manifest or a config file for my library - but it doesn't work, either. 

Does anyone have any suggestions? Would be much appreciated!
