Beware new formatted debug output
The new formatted API for .NET4:
Debug.WriteLine(stringFormat, intValue);
works as expected but may lead to a false sense of security that:
Debug.WriteLine(stringFormat, stringValue);
will also work but this instead calls one of the legacy overloads instead.
To work around this issue, cast the stringValue argument to an object or ensure there are at least two format arguments, adding e.g. null if necessary.
