When I create a new web project with Visual Studio, I only see the templates in the picture below:
The MVC one is missing and so I can only create empty projects.>
For me, I saw none of the MVC templates (except the bottom two), after installing Update 3 which installed all the Core stuff.
Solution
I downloaded most recent core preview...
It prompted me for "repair" and after it was done, bringing up VS indicated it was "Installing Templates" and they appeared!
Warning
Update 3 is a game changer in that the "preferred" way of doing things is to use dotnetcore. For example a console application now uses the new file stucture, other projects such as a Test Project still use the same folder structure as before. But MVC has changed. I'm not even sure what other "Web Developer Tools" work with dotnetcore right now.
