DLL depends another DLL but windows can't find it
I am working on an application where users can develop their own plugins as dll files. They need to put these dll files to a specific path so my application(C++) can load them and run. The problem is, when user develops a dll file depends another dll file and put both files to my dll path, my application can't find second dll file.
Ex:
DllA(C++) depends DllB(C#) my app loads DllA but can't find DllB and fails.
If user puts DllB into application binary path and DllA to specific dll path, I am able to execute plugin. I also tried to put DllB into various directories such as windows or system32 but it again fails. I also tried to add my dll path to PATH environment variable but no effect.
I am already executing SetDLLDirectory function to load DllA in the specific path. Since I've no control over user code, I can't make them to call this function in DllA code also. My question is that how can I force windows to search my specific dll path?
