  • Where is single page application template in visual studio 2012, its gone?

      --- Hi, Alberto, Please visit for detailed information, basically, An official release of ASP.NET SPA won’t be ready in time to ship with the final ASP.NET MVC 4 release. You can find the source code for ASP.NET SPA and follow the development effort on the ASP.NET  CodePlex site.  -- Xinyang Qiu Web Platform and Tools team

  • I tried to used the inbuilt Javascript Console in Visual Studio 2012 on a Windows 7 machine with IE9. But it gives me an error saying "The installed version of Internet Explorer does not support the browse diagnostics windows.". I get the same error with the DOM Explorer too. Any solutions on how to fix it ?

  • Hi, Manoj,

    JavaScript console and DOM explorer on VS2012 only works with IE10, so you can get it work on windows 8 or download an IE10 pre-release version for Windows 7.  It's the same as IE10, just that you can do the same work in VS as well as in IE10's F19.

    For win7/IE9, you can just use IE9's F12 functionality.
