I have a computer with XP Pro, and want it to work with NET Framework 2.0 and later. However I’m unsure what to actually install..
Looking at this page for NET 2.0: http://msdn.microsoft.com/en-us/netframework/aa731542.aspx
Do I need to download both the redistributable version, and ALSO the 2.0 SP2 package?
Also the same question valid for 3.5 download from here: http://msdn.microsoft.com/en-us/netframework/cc378097.aspx
If I later find out I need NET 1.1, will that be ok to install after all the later NET Frameworks?
You only need to install .NET 3.5 any application written for another lower version will work.
You don’t need to install .net 2.0 or 1.1 later.
Generally if you install .NET 4.0 you should be able to run any proram written for a lower version. However there might be problems and this might not always be true in the case of .net 4.0. Check this out for details.
