I'm trying to decompile the windows photo viewer DLL files to try to tweak them, such as editing speed etc. Since this wasn't possible in the registry.When opening the files in a program such as ILSpy or dotPeek, I get a message that looks like this: This file does not contain a managed assembly.I'm rather new to reverse engineering things so could anyone tell me what I'm doing wrong here since the programs say it's a .NET Framework 4.5 application.
