Correct way to implement C# console application?

Question

What is the correct way to implement and architect a command line tool as a C# console application?

Concerns to address include proper parsing of command line variab

Answer 1

As for command line arguments, you'll find various schemes, but I've always been a fan of

app.exe "self-explanatory arg" /noArgumentSwitch /argumentSwitch="argument"

As for the return code, you can change the signature of your Main() function to return an int rather than void. This will allow you to return a code to the calling process, if necessary.

As for the error stream, I've never personally used it, and I don't think that it should come at the expense of outputting error information in the standard output stream. It's probably better used for specific error debugging information.
