Blazor Server is a stateful app framework. The app maintains an ongoing connection to the server, and the user's state is held in the server's memory in a circuit. One example of user state is data held in dependency injection (DI) service instances that are scoped to the circuit. The unique application model that Blazor Server provides requires a special approach to use Entity Framework Core.

In this tutorial, you will learn how to configure an OData API, integrate it with Entity Framework Core, and call the API from a server-side Blazor front-end targeting .NET Core 3.1.
