Installing and Using the Entity Framework Core CLI Tool (dotnet-ef)

The command:

dotnet tool install --global dotnet-ef

installs the Entity Framework Core (EF Core) command-line tool globally on your computer.

It allows you to manage Entity Framework Core databases directly from your terminal.

Command	Purpose
`dotnet ef migrations add InitialCreate`	Create a database migration
`dotnet ef database update`	Apply migrations to the database
`dotnet ef migrations list`	List existing migrations
`dotnet ef dbcontext scaffold`	Generate models from an existing database

If your .NET Web API uses Entity Framework Core:

dotnet ef migrations add CreateUsersTable
dotnet ef database update

This creates a migration and updates your database schema.
