I have an ASP.NET / C# solution in VS2010. The Target Framework property for each project is set to .NET Framework 3.5, however:

When I debug the ASP.NET site, using the built in ASP.NET Development Server, the properties pane of the server show we’re running in ASP.NET Version: 2.0.50727.4955.

Are there any other Project / Solution settings I should be updating?

Thanks for any help.

Chris.

    The .NET Framework 3.5 is in fact an extension to .NET 2.0, so this is probably correct.

    What I mean is that the .NET 3.0 and .NET 3.5 classes are merely extensions to .NET 2.0, so the main classes are all still version 2.0.

    Go here to see what I mean: %SYSTEMROOT%\Microsoft.NET\Framework

    The v3.0 and v3.5 directories don’t contain much, just the new stuff (eg v3.0 just contains WPF, WCF, WWF stuff).
