Question

System.Diagnostics.Trace, System.Diagnostics.EventLog, and System.Console all seem to be unavailable. Does WinRT include a logging library?

Answer 1

The only thing I was able to find (System.Diagnostics.Debug.WriteLine()):

    //
    // Summary:
    //     Writes a message followed by a line terminator to the trace listeners in
    //     the System.Diagnostics.Debug.Listeners collection.
    //
    // Parameters:
    //   message:
    //     A message to write.
    [Conditional("DEBUG")]
    public static void WriteLine(string message);

It writes to the debug output of the Visual Studio’s output window.
