Where is the .AddDBContext method?

Question

He said everywhere to call the services.AddDBContext <> method, but it is not recognized inside the ConfigureServices method (IServiceCollection services).
What am I doing wrong?

Answer 1

Microsoft.EntityFrameworkCore.SqlServerfor SQL Server, Microsoft.EntityFrameworkCore.Sqlitefor SQLite, and Microsoft.EntityFrameworkCore.InMemoryfor memory (for testing only).

These are official service providers. There are also third-party providers of PostgreSQL, MySQL, etc. Documentation providers provide a list of available third-party providers here .

(, Oracle MySQL) MySQL.Data.EntityFrameworkCore.Extensions, using MySQL.Data.EntityFrameworkCore.Extensions;
