title: How do I determine whether ASP.NET 3.5 is installed on Windows Server 2008 r2
body: <p>I hate to ask a question that seems like it should be easy to find the answer to on the web, however I am unable to find a straightforward answer anywhere as to how to check what version of ASP.NET is installed on my Windows Server 2008 r2. Any help with this would be much appreciated. Kind regards, Jon</p>
