Using a non-plugin DLL

[gegy1000]

I am working on a plugin that requires a DLL (C), completely unrelated to Unity or KSP. With this, I need to call certain functions through PInvoke, so I have put this DLL in the same directory as my plugin. However, when KSP starts up, it tries to load this DLL as a plugin, which it is not, and prints this error into the log:

System.BadImageFormatException: Format of the executable (.exe) or library (.dll) is invalid.
  at Mono.Cecil.PE.ImageReader.ReadOptionalHeaders (System.UInt16& subsystem, System.UInt16& dll_characteristics) [0x00000] in <filename unknown>:0

How can I prevent this DLL from being loaded as a plugin?

Thanks.

The only way to do that would be to change the file extension of the dll and using the new one in the DllImport attribute. But it is safe to ignore the error message in the log, KSP won't try to mess with the native DLL. (Principia is the best example)

Thanks, I changed the extension and it works great!
