Entity Framework Core Tracking Issue: “The instance of entity type ‘Product’ cannot be tracked”
I’m encountering a tracking issue in Entity Framework Core while trying to create multiple Product
entities in my ASP.NET Core application. The error message I’m getting is:
System.InvalidOperationException: The instance of entity type ‘Product’ cannot be tracked because another instance with the key value ‘{Brand: hteye, Style: wqefwef, ColorName: Red}’ is already being tracked. When attaching existing entities, ensure that only one entity instance with a given key value is attached.
