This MSDN article explains this quite clearly:

The version of the .NET Framework that runs the application as follows:

• If the version of the .NET Framework that the application was created against is present on the computer, the application runs in this version.

• .NET Framework <supportedRuntime> , .NET Framework, .

• .NET Framework <supportedRuntime> , .

Answer 3

Starting with Visual Studio 2008, you can target a specific version of .Net Framework - 2.0, 3.0, or 3.5

Until VS2008 its fixed -

VS2005 Goal .Net Framework v2.0

VS2003 Goal .Net Framework v1.1

VS2002 Goal .Net Framework v1.0

If you specify a target, it will require that version of the .NET Framework.

CORRECTION: it will work on the THAT version or higher, compatible.
