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?

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.
