    The CorDebugger backend (which is used for Microsoft's .NET runtime, as opposed to the SDB debugger backend which is what is used with the Mono runtime) is known to be broken for 64bit apps.

    The workaround is to install the Mono runtime and set it as the target runtime instead of the Microsoft .NET runtime.

    Another workaround would be for us to ship an /platform:x86 build of xsp with XS on Windows. Not sure how easy it easy to change the bundled xsp exes though.

    I'm having the same problem with a MVC3 web app in Studio 4.0.3.
    How do I switch over to the SDB debugger?

    How do we switch over to the SDB debugger?

    I gave up to dubug aspx with xamarin on Windows 7 64 bits. Never Succeed.
    I stay on VS 2010. Will be a new customer for Xamarin (that i love) when Debugging aspx works. I have the goal to switch gently to linux (Ubuntu), using Mono everywhere i can.
    Hope one day, we will be able to compile for android and ios on Ubuntu

    Keep up the good work.
