How about this:

Look for methods that calls "<type> <type>.Parse(string s)"
and warn if "bool TryParse(string s, out <type>)" exists - maybe with an higher
severity if the code is not inside a try/[catch|finally] block.

That way it won't be limited to the BCL types (a moving target with 4.0 coming

Another (design this time) rule could be to implement TryParse alternative when
a Parse method is found.
