I have read a lot about async/await being implemented (internally) as a state machine, and would like to know if I can use the VS2012 compiler, while still using Net version 4 as my runtime to use these new features?

I remember that I could do this with several new features of Net 4 while still using Net 3.5 but with the VS2010 compiler.

Thanks,
Martin.

    Right from the Visual Studio Asynchronous programming page:

    http://msdn.microsoft.com/en-us/vstudio/async.aspx

    If your Visual Studio 2012 project needs to target Silverlight 5 or
    .NET Framework 4.0, you can use the Async language support by
    downloading the Async Targeting Pack for Visual Studio 2012. This
    pack is not required for projects targeting .NET Framework 4.5 or .NET
    for Windows apps.

    So yes, you can download the Async Targeting Pack for Visual Studio 2012 and use the async programming features while still targeting .NET Framework 4.
