How to fix "Could not load file or assembly WebMatrix.Data"?

Question

ASP.NET

There was a stably working project, a rather simple landing on MVC4, for the sake of experiment I started the project up to MVC5, it didn’t work, it rolled back completely. After that, the project stopped building. With the error
"Failed to load the file or assembly "WebMatrix.Data, Version=2.0.0.0"
The project is completely reversed to the state before the update, but does not work.
Googled, it is recommended to install an additional nuget, I tried it, it did not help. Because WebMatrix.Data in References there is alias global and an exclamation point opposite How to cure, I have already spent 4 hours trying to restore the environment.

Do you need it or not? If not needed, remove the reference. If needed, remove the reference and add via Nuget package management
