Target Framework drop down selection missing other frameworks RRS feed

  • Question

  • I have a successful install of VS2010, however, I can't target any versions of the .net framework other than 4.0 and 4.0 client profile. When I open an existing project that targets other versions of the framework I get a "Project Target Framework Not Installed" error. When I create new projects visual studio only allows the selection of 4.0. I have 1.1, 2.0, 3.0, 3.5 all installed. IIS can run ASP.NET apps build on all of these frameworks on the computer. Visual Studio 2008 (also installed on computer) targets back to 2.0 (as expected).

  • Thank you for Ferry's kindly help.

    Hi Rob,

    As Ferry mentioned, to target other .NET Framework like .NET 2.0, 3.0 and 3.5 in Visual Studio 2010, we need have these .NET Frameworks installed and upgrade .NET Framework 3.5 to SP1 on the machine.

    Some clarification with you:
    What's your OS?

    Since you have installed .NET Framework 2.0, 3.0 and 3.5 on your machine, could you please help me to use Verification Tool to verify .Net Framework 2.0, 3.0 and 3.5?
    If .NET Framework 2.0, 3.0 and 3.5 can be verified successfully, please try to upgrade .NET Framework 3.5 to SP1 by download .NET Framework 3.5 Service Pack 1 or Visual Studio 2008 SP1 which will upgrade both .NET Framework 3.5 and Visual Studio 2008 to SP1.

    Hope this helps! If you have any concern, please feel free to let me know.

  • Hi Rob,

    Thank you for your reply.

    Even you apply Visual Studio 2010 and .NET Framework 3.5 SP1 on WMWare, I think that the steps should be the same. You can try these steps on the virtual machine.

    Please feel free to let us know the result whether it succeed or fail.

    Look forward to your feedback.

  • Given the MS documentation indicates the requirement I'm betting, since I don't have 3.5 SP1 installed that is my problem. Therefore, i'm planning to move forward. Would still like me to run the verifier tool? I can using VMWare snapshot prior to installing 3.5 SP1. If so, would you want the results posted here?

  • Installing .NET 3.5 SP1 did fix the problem. I must admit it very plainly expressed as s dependency in the VS documentation.
