I'm starting to develop in ASP.NET again and I ran into a small error within Visual Studio. My .cshtml files show errors when using a few razor functions. For example "The name 'ViewBag' does not exist in the current context". Here is a picture: http://puu.sh/gT6yg/4b44319fa7.png
I am using a demo project. You can find the project here: https://github.com/Wintellect/Angular-MVC-Cookbook/tree/master/BasicProject
I have looked through several other threads and most suggest to update the web.config file(s). These 2 config files are already present and since it's a pretty popular demo I assume it has all the required configuration in it. I have of course looked through these config files and they do indeed include the suggested solutions.
I had this issue despite having all the correct configuration.
It turned out to be some bad files in the Component Cache, preventing the Razor views from recognising ViewBag, Model, and HtmlHelpers. Deleting these files solved the problem (good versions of these files were created next time I opened Visual Studio).
The files are located here:
Delete all four files:
I have subsequently seen the same issue on several other developer machines and this fix quickly solves it.
