Trying to edit and change target framework in *.csproj file

Question

I have a project which was in asp.net MVC 4.0, Now I updated my project MVC version from 4.0 to 5.2. After this update, I have lost my IntelliSense from all my *.cshtml files, that's OK still I can work without IntelliSense but suddenly I don't know what happened with my project all the *.cshtml files in a project are not opening. Below message is showing when I trying to open the *.cshtml file.

I think there is an issue with my .csproj file, In that file the target framework is still is 4.0

Can anybody suggest do I really need to update .csproj file for open the *.cshtml pages and enable the IntelliSense ?

Thanks in Advance.

Try changing the target framework. If you are using 4.0 try to make it 4.5.
