MonoDevelop output from a C# code (on a Mac)

Question

I'm using MonoDevelop on a Mac. I wrote a program, I made sure it is correct MonoDevelop has all necessary to build an exe file from it. MonoDevelop says "Build Successful." However, no output appears. When I select "Run", I'm told:

Cannot open assembly '/Users/.../Projects/.../.../bin/Debug/XY.exe': No such file or directory.
The application was terminated by a signal: SIGINT

And, indeed, no exe file has been created. Do you know how to create the exe file?

It seems like many things don't work without Xamarin. This was one of them. Installing Xamarin solved the problem.
