How do you integrate Entity Framework Core with Web API?

Mid ASP.NET Web API Published: Nov 22, 2025

Quick Answer EF Core integration: install EF Core package + DB provider (EF Core SqlServer, Npgsql). Add DbContext via AddDbContext() with connection string from config. Use Scoped lifetime (one instance per request). Access entities via DbSet. Use async methods (ToListAsync, FirstOrDefaultAsync) for all DB operations. Apply migrations to manage schema changes.

Answer

To integrate EF Core with Web API:

Install EF Core packages such as Microsoft.EntityFrameworkCore and Microsoft.EntityFrameworkCore.SqlServer.
Register your DbContext in Program.cs using AddDbContext.
Inject DbContext via constructor injection in controllers or services.
Use migrations and LINQ for strongly-typed database access.
