From the docs:
7. The generated project does not depend on
ASP.NET MVC being
installed on the development machine. While this is good for
compatibility with multiple versions of MVC, the drawback is that
ASP.NET MVC item templates are not available within Visual Studio by
default. If you have
ASP.NET MVC installed and you’d like to have the
item templates available, do the following:
a. Using Windows Explorer, browse to the generated project and
open <YOUR PROJECT>.Web.csproj with Notepad.
b. Insert the following immediately after the opening
<ProjectTypeGuids> tag, and before the other GUIDs: “{603c0e0b-
db56-11dc-be95-000d561079b0};”
c. Save and close the csproj file; you’ll be prompted to reload it
in VS.
