Our new project has opened. Go to Tools >> NuGet Package Manager, and click “Manage NuGet Packages for Solution”.
Now, the NuGet – Solution window will open. Select "Browse" in NuGet Solution and enter “entity framework core” in the search box. We get many lists after entering the keyword in the search box, the list looks like below screenshot. Locate “Microsoft.EntityFrameworkCore”.
If we are using SQL Server as a database, we can only install “Microsoft.EntityFrameworkCore.SqlServer”.

Entity Framework Uninstall
We can uninstall Entity Framework from our project or our solution very easily. Go to Tools >> “NuGet Package Manager” >> “Manage NuGet Packages for Solution”.
Type “Microsoft.EntityFrameworkCore” in the search box and get lists. We see a green tick mark on items that are already installed in our solutions.
