What is the exit code for a C # program that throws an exception from the main one?

Question

In a C # program, what is the exit code defined as an exception thrown from main? I know that you can set the exit code in several ways, as described in this excellent answer . But I am very surprised that I can not find the documentation for which the value of the exit code is determined when the exception is thrown from the main one. Is there a standard that defines what the meaning of the exit code will mean in this case, or depends on the operating system (or chance or something else)?
