Description

Currently the configured 'frameworkVersion' on 'npanday:compile-maven-plugin:compile' is both the 'targetFramework' and 'toolsVersion'.

But since .NET 3.5, there is support for socalled "Multi-targeting" in Visual Studio: In other words, target old CLR versions with newer tools.

Since .NET 3.5 is just a new C# compiler + System.Core.dll, this can still target CLR 2.0.

Also .NET 4 Co/Contravariance-Support and NamedParameters can be targeted to CLR 2.0.
