Expression of type 'System.Web.Mvc.MvcWebRazorHostFactory' cannot be used for return type 'System.Web.WebPages.Razor.WebRazorHostFactory'

Question

I am getting this error when I try to run a project that I took over.

I assume I have a problem in my web.config, but I don\'t know what to look for.

Answer 1

I got the same error. What worked for me: Right-click on your project and select Manage NuGet Packages. Install Microsoft ASP.NET Razor. Rebuild the project.
