Yes you can do this in Visual Studio and it is called Multi-Targeting.

Scott Guthrie has a great blog-entry on Multi-Targeting Support in Visual Studio.

VS 2008 was the first release of Visual Studio that included multi-targeting support for .NET. What this meant was that you could use VS 2008 to create and edit not only .NET 3.5 projects, but also .NET 3.0 and .NET 2.0 projects as well. This allowed developers to more quickly upgrade and take advantage of new Visual Studio tooling features – without having to necessarily require the newer version of .NET to be installed on the clients and production servers running their applications.
