         the resulting compilation constant will be a valid C# conditional compilation symbol.  As the set
         of characters that aren't allowed is essentially open-ended, there's probably not a good way to
         fully sanitize the Configuration in MSBuild evaluation.  If the resulting string still isn't a
         valid conditional combilation symbol, then the compiler will generate the following error and
         the define will be ignored:
            warning MSB3052: The parameter to the compiler is invalid, '/define:0BAD_DEFINE' will be ignored.
