【问题描述】：

I am using visual studio with sql server, i am in a middle of a practice and faced a major issue. The issue was in the first place, when i was creating a product table , by mistake i mistyped as a categoryId ctegoryId, and later i recorrected it by thinking its over.

And now I am almost done with the identity scaffolding when updating my database, I am facing such an error. and I\'ve tried all ways to update it by myself but failed. I need an expert guidance so I can continue my path till the end.

I do appreciate any solution from your side.

Thanks indeed [Migration error \"Each Table must be unique\"](https://i.stack.imgur.com/tB3iT.png)

Include your product class here in your question instead of screenshot.
What if you run this command Add-Migration -IgnoreChanges and then run Update-Database
