Mono has a UNIX console driver, and a Win32 console driver. It's selected at compile time, so on a Windows build, only the Win32 console driver is available.
Several methods in System.Console return bad values if executing in Cygwin (which has a "real" UNIX console, with a tty and everything, not a Win32 console). For example, Console.WindowWidth returns 0, which prevents csharp REPL from running in Mono in Cygwin.
Jo, is that still the case today? If so, could you please come up with a test case, and an expected vs observed behavior. Thank you.
