问题 My first question here, I hope someone can help me out. I'm new to developing ASP.Net applications and have recently completed a small project based around racing drivers, teams etc which works fine locally but not when I've deployed it to Azure.

问题 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. 回答1: I got this for ages, all I did was upgrade the nuget packages for Mvc and it fixed it.
