How to open MVC 2 or MVC 1 in Visual Studio 2013

Step 1: Right click on the project and click “Edit projectname.csproj”.
Step 2: In the opened file find the tag and from there delete the following GUID:
ASP.NET MVC 2: {F85E285D-A4E0-4152-9332-AB1D724D3325}
This actually works also for ASP.NET MVC 1 projects
ASP.NET MVC 1: {603c0e0b-db56-11dc-be95-000d561079b0}

Step 3: Save the file and reopen the solution in Visual Studio.
