System.ServiceModel disappear
<p>After installing .Net Framework 4.0 it seems like I cannot find System.ServiceModel in .Net tab through "Add Reference..." by using VS2008. But you can see it and add it in VS2010 version.</p>

<p>Can someone tell me why, and how I can have both version, and still can use it in VS2008?</p>

<p>Thanks</p>
