If .NET 3.5 SP1 is missing, can I install 4 directly?

Question

When I need functions from .NET 3.5 SP1 on a system without it, can I install .NET 4, or do I need to install .NET 3.5 SP1 as well?

Answer 1

.NET 4.0 is not related to .NET 3.5 (the .NET 2.0 runtime). It has its own runtime, .NET 4.0 is completely separate from .NET 3.5 and lower versions of .NET.

Thus, you can install .NET 4.0 without fear that you are missing .NET 3.5 SP1. But keep in mind that some applications may require .NET 3.5 SP1. In any case, there should be no problem installing .NET 3.5 SP1 later.
