If I have different .NET frameworks installed on my machine (i.e. 1.1, 2.0. 3.0, 3.5), is it possible for VS2005 to select with which framework to create / compile an application (Winform/Webform)?

            No, you need to use VS2008 to do that.
Even then you can only choose between 2.0, 3.0 and 3.5.

            No this is not possible in Visual Studio 2005. Visual Studio 2008 supports a version of multi-targeting which allows you to target either the 2.0, 3.0 or 3.5 framework. It does not however allow you to target 1.0
ScottGu did a lengthy blog post on this subject that you may find worth a read:

            In VS 2008, you can select a target framework (by right clicking onthe solution) but not from VS 2005.

            Only the 2.0 CLR based (that is 2.0, 3.0, 3.5, 3.5SP1) targetting is allowed unfortunately.
