Hi JB, I have logging code in MethodWeaver.dll. This dll has class Lgoger and method Logtext.
Using Mono Cecil I have injected code Logger.LogText() into another exe as external CustomerApp.exe. When running code getting error like "access to method Logger.LogText() failed." It seems MethodWeaver.dll should be added as external assembly reference into CustomerApp.exe. Can you please help? Thank you!
