I was working on back-end of existing ASP .NET MVC project for some time and all of it was building splendidly.

But now as time came for some front-end, as soon as I open (just open) one of the views it all starts glowing red and the project doesn't build anymore with numerous errors as:

CS0246 The type or namespace name 'System' could not be found (are you missing a using directive or an assembly reference?)

CS8023 Feature 'lambda expression' is not available in C# 2. Please use language version 3 or greater.

CS0012 The type 'WebViewPage<>' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Web.Mvc, Version=5.2.3.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.

I have triple checked I have all the references. How could I possibly resolve the issue?

Have you tried Cleaning your Solution? Build > Clean Solution. Then try and build. – Jamie Rees Jul 19 '16 at 15:44

Likely there is a reference in the web.config file that is in the Views folder and it conflicts with the version of the System.Web.Mvc assembly that is referenced. – Glenn Ferrie Jul 19 '16 at 15:44
@JamieR Sure, it works if none of the views are opned. – Antonio Black Jul 19 '16 at 15:47
@GlennFerrie I have no web.config in the View folder. – Antonio Black Jul 19 '16 at 15:48

@AntonioBlack, not having a web.config in the view folder might be the problem. http://stackoverflow.com/questions/23509617/why-does-net-generate-two-web-config-files-in-an-mvc-asp-net-application – Jeff Siver Jul 19 '16 at 15:51
