title: How to install .Net Framework 2.0 without harming 3.5 and 4.0 already installed?
body: <p>I've got quite a complex .Net 2.0 project to build (with VS 2010) which does not build without 2.0 version of System.ServiceModel.dll and does not run if compiled with .Framework 4.0. Can I install Net Framework 2.0 safely after 3.5 and 4.0? Or where can I download an old System.ServiceModel .dll assembly?</p>
