After getting latest in Visual Studio 2015 Community, some of my Razor syntax is showing red Intellisense errors. Items like @Html.TextboxFor() and @Html.CheckboxFor() are throwing the following error:
The type 'Expression<>' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
I have attempted the solutions listed under the following: VS 2015 IntelliSense: Assembly Not Referenced Error, The type 'Expression<>' is defined in an assembly that is not referenced.
Neither one of these issues fixed the problem. Are there any other issues that could be causing this problem?
