Allow for IIS Express 64 bit to run from Visual Studio 2012

Right now when you have a 64 bit Web project in Visual Studio 2012 it will always launch the iis express 32 bit version. Can we make Visual studio smarter depending on the platform on what iis express to load. Or at least allow for us to change that path inside the csproj file?

        Well, I came across this issue while uploading the file as large as 150MB. @dadvav suggestion works for me. I am glad I don't have to go through the scary registry.

        "This has been fixed in Visual Studio 2013"
        Are you sure?
        I still have problems.
        Why don't you add a manual setting for this also?

        This is completed-ish. Although IIS Express can run in 64-bit mode, the most clear way to get it to do so in VS2013 is to set a Registry key so it always does, which isn't really in the spirit of what people were asking for. They wanted something responsive to the settings on a Project in Visual Studio. They got something really buried, with a system-wide switch.

        I also have this problem in VS 2013. Setting the reg key as described below for VS 2013 made it work.

        You can configure Visual Studio 2012 to use IIS Express 64-bit by setting the following registry key:

        reg add HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\11.0\WebProjects /v Use64BitIISExpress /t REG_DWORD /d 1

        However, this feature is not supported and has not been fully tested by Microsoft. Improved support for IIS Express 64-bit is under consideration for the next release of Visual Studio.
