We have an old ASP.NET MVC 3 Web Application, building in VS2010, that fails to compile, since last week\'s security update.
The problem is that the reference to Sys
The sample mvcmusicstore.codeplex.com opened in vs2015 missed some references, one of them System.web.mvc.
The fix for this was to remove it from the references and to add a reference: choose Extentions under Assemblies, there you can find and add System.Web.Mvc.
(The other assemblies I added with the nuget packages.)
