Your project is targeting .NET Framework 2.0 or 3.0. If your project uses assemblies requiring a newer .NET Framework, your project will fail to build. You can change the .NET Framework version by clicking Properties on the project menu and then selecting a new version in the '.NET Framework' dropdown box. (In Visual Basic, this is located on the Compile tab by clicking the 'Advanced Compiler Options...' button.)
