Entity Framework Code First (2021, DotNet Core or DotNet 5)

Показать описание

Entity Framework Code First from scratch - build a new project and create data classes, then generate the database from your models using Entity Framework (Code First). This video also shows you then how to query the database using EF after you have generated the schema, and up to apply migrations to update/scaffold the database. Examples are in SQL server but could be applied to other similar databases like MySQL.

As someone coming from Dapper, this saves so much time and works like magic!

Great job! I was looking for a great guide on this topic and here it is. 🦍

Good presentation. Everything was clear. Here are my questions. 1. How do you use the data annotation to display error messages in a production environment especially the required attribute. 2. Is dependency injection supported in console or window application when using entity framework core in these environments.

Source code is here at this github link, but I advise watching the video first as it will explain the where/why and how to generate the generated portions..:

It's insane how much extra work you have to do for codefirst development. I'm baffled that anyone thinks this is a good idea.

Hello. I am using Mac with M1 chip. I tried command ' dotnet ef database update ' but I got this error:

LocalDB is not supported on this platform.

Do you know what is the problem?

Thank you so much!

This keeps happening where the comments show up in my email but don't make it to the channel. Perhaps your comments are being flagged? Responding to @Mitesh M If you have a local connection from your pc to sql express, then you can setup either sql server authentication or you can setup windows active directory authentication. If you use the default ad connection we can use 'trusted connection', and so your connectionstring may be similiar to this: Trusted_Connection=True;" and don't use the double backslash (just one backslash) if you are referring to the EF console command to generate scaffolding or models, etc. use the double if its in appsettings.json. Hope that helps you and/or someone else and hopefully your comments start showing up!

Thanks for your video, but Entity Framework is totally removed from our system, it's just too messy and difficult to maintain for all developers. It could work in a very small system but not the enterprise level! Not sure what Microsoft was thinking when they implemented this!

Wait a minute. Before you scaffolded and performed a database update, the database itself already exist, you only added the tables to it. Right?
