How to resolve @ViewBag, HtmlHelper and Linq errors on compile with Visual Studio and MVC 5.2
So I have this code and the screen shot displays the only 3 errors left out of 13.
I've updated VS and MVC to 5.2.
Here is the controller for ViewBag or where it exists in the code:
I need to find a solution for resolving this. I've scoured the web and Stackoverflow to see about fixing this issue but I cannot. I'm new to .NET and C# but as you've seen in previous threads, I'm more Typescipt and Angular 7 which, actually, helps me to understand the code structure. Funny how the code globally, is all coming back together, hmm?
So, if anyone has any thoughts or needs more info, please do not hesitate to ask and I'll gladly post more examples.

UPDATE:
Fantastic Suggestion...
Here's what worked.
Exit Visual Studio Delete all non-project files (bin, obj. .vs, _ReSharper.Caches folders, *.suo files, ...) Start VS and rebuild That fixed it for me.
Then I got the webpages:Version" value="2.0.0.0" was incorrect and bin had 3.0.0.0
I changed the 2.0.0.0 to below and POOF!!!
The application lit up like a Christmas tree!!!
THANK YOU! <--- YOU SHOULD leave this because I mean it and I got the help from the int'l community when a local friend simply ignored me. This is what SO is all about.
<add key="webpages:Version" value="3.0.0.0" />
Solution
Your Razor view should start with imports of namespaces you're using. In this case that would be:
@using System.Linq
However, the ViewBag property and HtmlHelper extensions should be accessible by default. Which they don't seem to be. Which leads me to believe something is not configured properly.
As to how to fix that, this SO question might be of help:
