How do I add and delete data in the crosstab later using Ef Core 6?-CodePudding

I have PostgreSQL database, and three tables in that. These are;

Categories

UploadedFiles

CategoryUploadedFiles (This is my cross table)

When I import this tables to my project with DbFirst method it doesn't create the cross table. (CategoryUploadedFiles) I need to add and remove manually in my cross table but I can't because it doesnt't created.

How can I do it?

CodePudding user response：

You should declare a new class named CategoryUploadedFile and add this class to your DBContext.

Added primary key to my cross table. (Id) So the entity object was imported into the project.

Thank you written answer users to my question.
