Cannot add view to ASP.NET MVC 5 project

I'm trying to add a view to an ASP.NET MVC 5 project in Visual Studio 2013, but the Add button is greyed out.


I got this for ages, all I did was upgrade the nuget packages for Mvc and it fixed it. I suspect that I had a mismatch of versions in the solution.

Update-Package Microsoft.AspNet.Mvc -Version 5.2.3

The version part is optional, but it should mean that all projects get the same version.

Different from the OP issue (as I'm on VS2017) but in case anyone else comes to this question when they've made the same (basic) error as me...

It took me a few minutes to realise that if you type in a new Model class (as seen below) then this is not what the UI wants; it requires you to select an existing Model from the dropdown. Once I created the model and then selected it 'Add' was enabled.

You should create a controller first, then it will create a View folder automatically. Try to right click that file then click create new view. Also Copy might be a specific name, you may need to change that name.
