ASP.NET MVC Core Web Application

I created ASP.NET MVC Core Web application project in Microsoft Visual Studio 2017. I installed Entity Framework from Nuget Packages but when i want to add Entity Framework in my project, it does not appear in the Add New Item dialog box under the data.

 

Please guide me how to add Entity Framework to ASP.NET MVC Core 2.1 Web Application in Microsoft visual Studio 2017. I recently switched to Microsoft Core from .NET Framework.

 

Thanks in advance
