I'm trying to run the solution with visual studio 2013
but I'm having an error when tying to open (WebUI)

it keeps saying that I have a missing project subtype

and this is written in my migration report
Survey.sln: Visual Studio needs to make non-functional changes to this project in order to enable the project to open in Visual Studio 2013, Visual Studio 2012, and Visual Studio 2010 SP1 without impacting project behavior.
