I've build all binaries and tried to reproduce your happy path, but ... can't
My command line was
Injector.exe SampleNetApp.exe NativeDLL.dll NetDLL.dll NetDLL.Injected InjectedMethod ""
this is what I"ve got:

the effect on the running SampleNetApp.exe is that it is hanging - main window got white and does not show the button
do you have any clues what might got wrong?
