When i tried to install sql server 2005 express in a windows XP( fresh installation of Windows xp with no .net framework) setup asked to install .net framework 2.0. But i had installed .Net 4.0 extended version and then again tried installing sql server 2005 express. I am shocked to see that it again asked to install .net framework 2.0. So if i have .net 4.0 then is it necessary to install .net 2.0 again? Anyway .net 4.0 is new version than 2.0 then why does it asks for .net 2.0?

Yes, .Net 2.0 is a prerequisite for SQL 2005 Express. So you will need to install it even though you have .Net 4.0. .Net 4.0 has a different CLR version (4.0) than .Net 2.0 (CLR version 2.0).

.Net 2.0, 3.0, 3.5 all were built on top of CLR 2.0, so you might as well install .Net 3.5 SP1 instead of .Net 2.0. SQL 2008 requires .Net 3.5 SP1, so in case you decide to upgraded to SQL 2008 this way you will be covered.

So download and install .Net 3.5 SP1 from here:
