The type or namespace name 'Mvc' does not exist

Solution 1:

The source of your error may be that you do not have a reference to the MVC framework library. A simple solution is to add this reference trough Nuget. The MVC library will be installed in your bin directory and, if needed, all the references will be added to your project.

Either browse for the MVC package (Tools -> Nuget Package Manager -> Manage Nuget Packages for Solution) or install it using the Nuget console (Tools -> Nuget Package Manager -> Package Manager Console) by entering Install-Package Microsoft.AspNet.Mvc. You can find additional information on the official Nuget page for AspNet.Mvc.

Solution 2:

My solution was to simply open up the nuget package manager console and run the command update-package -reinstall Microsoft.AspNet.Mvc

Solution 3:

Sometimes the package version conflict becomes an issue where if you have the MVC package installed then it shows the namespace error.

Here is how I solved it:

  • Open Package Manager Console (Tools > NuGet Package Manager > Package Manager Console)
  • Type uninstall-package Microsoft.AspNet.Mvc
  • Type install-package Microsoft.AspNet.Mvc

So this will give your package a fresh start, you will have all new MVC references and no errors.
