In this video, we will learn how to Seed Initial Data into our PostgreSQL database using Entity Framework Core 10 in a .NET 10 Web API project.
Seeding is a very important technique used to automatically insert sample or default data into the database when the application starts. This is extremely useful in development and testing environments.
🔥 In this lesson, you will learn:
What is Database Seeding in EF Core
Why seeding is useful in real-world projects
How to use UseSeeding() and UseAsyncSeeding() (introduced in EF Core 9+)
How to insert sample data safely without duplication
How to check if data already exists before inserting
How to trigger seeding automatically on application startup
📌 We will implement seeding inside MovieDbContext and insert a sample movie record into the Movies table.
