Answer 1

Something is messed up with my overall project. I created a new project and copied the important items over and it all works now. I am not sure at all what is wrong with my original project.

Answer 2

First sorry for my terrible English. In my case, I use the MVC5 in Visual Studio Community 2015 and I solved the problem this way:

First I delete the cache of Visual Studio and NuGet cache:

• Visual studio - go to %LocalAppData% \Microsoft\WebsiteCache and delete all folder.
• Nuget - here

After I use the package manager console to remove PagedList.MVC, then remove PagedList and then re-install them again like so:

• uninstall-package PagedList.mvc
• uninstall-package PagedList
• install-package PagedList
• install-package PagedList.mvc

I holpe that help

Answer 3

I needed to add the namespace to the Views web.config file.

Details are in this SO post:

I then needed to close/re-open Visual Studio 2010 in order for it to recognize. Compiling the project didn't help (the web.config might only be read once upon project load).
