Some or many of these interop methods are not even used. Also, some duplicate system-provided interop, such as all three of the ones defined in Kernel32:
Kernel32.GetLastError -> System.Runtime.InteropServices.Marshal.GetLastSystemError
Kernel32.SetLastError -> System.Runtime.InteropServices.Marshal.SetLastSystemError
IsDebuggerPresent -> System.Diagnostics.Debugger.IsAttached and/or System.Diagnostics.Debugger.IsLogging
Also, the latter 2 have no references, and the former most has only 3 references, all from within comments of User32

I get that perhaps this is meant as just a "placeholder" class for possible future interop methods.

Consider migrating to https://github.com/microsoft/CsWin32 so you don’t have to write the native method headers yourself at all.
