Entity Framework Core + Blazor - Tutorial for Beginners

If you're a c# developer and you've not used it yet, you've probably heard of Entity Framework.

Entity Framework is an industry standard Object-Relational Mapping Framework for .NET that allows you interact with SQL through classes in C#, instead of directly executing queries against a database.

In this video, I take you through the basics of how EF can be used, with an example of it's implementation in Blazor.

[torrvic]

Thank you so much sir! That was a short and sweet video explaining some very important concepts. Honestly before this video I didn’t understood what was the point of using of Services . And now I understood that this is for data access and not to do it directly.

Great video! Really well explained and easy to follow.
I had a hard time understanding videos from others creators because they skip explaining the boilerplate stuff. I love the you take your time building each file instead of scaffolding everything.

Thanks for the video, i like how you can see the SQL query in the output window. Would be nice if you showed how to CRUD or atleast create with the order model since its a foreign key

Thx Nick. This is useful as a beginner. One question about the CustomerService method AddCustomer. We could also do it as async and call it AddCustomerAsync, correct ? Of course, the method signature would change to public async Action<IActionResult> AddCustomerAsync(), correct ? As a newbie, I am trying to understand when to use async/await and when not to.
