Показать описание
In this episode, Fritz begins accessing data using Entity Framework Core. We learn about create, read, update, and delete interactions with relational databases as well as interacting with one-to-many and many-to-many relationships in our database.

Questions:
00:21:57 What extensions are you using in Visual Studio Code for C#?
00:41:54 When would you go for a code-first vs database-first approach?
00:46:01 How do you sync the database schema to your classes if there is a change in the database?
00:47:45 Database First approach with EntityFramework Core just generates the classes?
01:06:12 What is AsNoTracking ?
01:12:07 Can you implement IPropertyChanged on the class Entity Framework returns?
01:36:06 What is the difference between DbSet and IEnumerable?
01:52:03 What are your thoughts on using the repository pattern in conjunction with EF Core?

So good to hear you don't have to create the join table model for many-to-many relationships anymore.

When Im trying to use GetPosts(db), AddPost(db) etc. I get unhandled exception „SQLite Error 1: 'no such table: Posts'.”) Even though I did everything step by step like in the video and when I use DB Browser I can see the Posts table
Could someone help me with that?
