adding reference to mvc project

Question

i have deleted System.Web.Entity by mistake from my mvc5 project in VS2017,How can ireplace it?

Files you delete in Visual Studio go to Windows recycle bin. Unless you cleared it, your files should still be there. Just restore them and than add them to your project as existing items. You can also drag and drop them through Solution Explorer.

You can use Nugut Packages to install the Microsoft.AspNet.Mvc package, then the System.Web.Mvc .dll will be added into the project's reference.
