I want to add a DLL reference to my project but I'm getting this error:

"x.dll could not be added. Please make sure that the file is accessible, and that is a valid assembly or COM component."

I've been searching on google but the suggestions that I've found couldn't solve the problem.
Any ideas or suggestions?

OK, and is it a valid .NET assembly or not?

can you explain how you are adding the DLL? That might give us more pointers for cause of error.

I can't be sure but is sounds like you may be trying to reference an unmanaged assembly? If so, try this: Using Unmanaged C++ Libraries (DLLs) in .NET Applications[^].
