I just downloaded and installed brand new Rider 2017.3 onto Windows 10 and started a new ASP.Net Core MVC project.
The template project it created shows the same error: ViewData, addTagHelper: cannot resolve symbol.
I googled the error and it seems to be a common problem, but no resolution !
Is it worthwhile to continue with Rider ?
I closed the project in order to do other things. Hours later I reopened the project and the symbols were recognized.That may work for you, another work-a-round is to turn off Resharper. When you first create the project you get all of warnings about ViewData and TagHelpers but the project will compile and run without problems.
