No i mean that there are bugs present in .NET 4.0 that are fixed in 4.5 yet i can't use 4.5 to resolve those issues because my clients (infact several clients') production environments are on Server 2003. My comment specifically pertains to ASP.NET websites/applications and has nothing to do with debugging.James commented
This is also an issue for ASP.NET websites running on Windows Server 2003. Yes, we all know users should now be running Server 2008 however in the real world budgetary and time constraints mean this isn't possible, particularly for large enteprise level customers or government departments.
