I know that the MS Validation Application Block can be used with ASP.NET MVC but I'm not sure if I should. It looks like it hasn't been updated since 2007 - which is probably fine - I'm just being extra cautious before adopting something new into my app that i haven't used before.
Is there any reason not to - or what does it do for me that is so great - or is there somethin upcoming I should wait for?
