asp.net mvc 3 - ViewBag.Title error

Question

Working against the current RC2 - the template that is generated Razor views includes:

@{
    ViewBag.Title = "Details1";
    Layout = "/Views/Shared/_Public.cshtml";

}

With a red squiggly under ViewBag.Title and this compiler error:'

Error   4   One or more types required to compile a dynamic expression cannot be found. Are you missing references to Microsoft.CSharp.dll and System.Core.dll? c:Visual Studio 2010ProjectsmyProjViewsWebinarDetails1.cshtml 6   2   TTSTrain.Webinars.WebEntry

But the project builds and functions correctly. Is the error indicative of other problems that should be addressed?

Answer 1

I got the same problem after I removed the targetFramework attribute from the <compilation> element in the Web.config file.

Once I restored it to

<compilation debug="true" targetFramework="4.0">

Everything worked fine again!
