WPF DataGrid on CustomControl

Hi, I need some help in WPF/XAML I have a UserControl for a PaginatesTable where I have a couple of WPF controls inside, TextBox, DataGrid, and some buttons for pagination, the main idea of the UserControl is to be reusable, so basically I have some PaginatedTableViewModel<T> which I initialize on each ViewModel of the Views and then I pass an ObservableCollection into PaginatedTableViewModel<T> to render those Objects But I need an approach to customize the DataGrid columns, Because obviously there are different properties on <T> Probably I want to do something like <PaginatedTable DataContext={Binding PaginatedTableViewModel}> <PaginatedTable.Columns> <!-- Customization of Columns —> </PaginatedTable.Columns> </PaginatedTable> I tried with DependencyProperty but I was not able tu make it reusable

❔ Entity Framework 7 model property as enum is giving conflicts when running migration

I'm trying to create a many to many "pivot" model where it haves 2 fields "GroupId" and "SubscriptionId"

public class GroupSubscription
    {
        public int Id { get; set; }
        public int GroupId { get; set; }
        public SubscriptionType SubscriptionId { get; set; }
        public Group Group { get; set; } = null!;
        public Subscription Subscription { get; set; } = null!;

    }

public class GroupSubscription
    {
        public int Id { get; set; }
        public int GroupId { get; set; }
        public SubscriptionType SubscriptionId { get; set; }
        public Group Group { get; set; } = null!;
        public Subscription Subscription { get; set; } = null!;

    }

I have a SubscriptionType enum:

public enum SubscriptionType
        {
            Basic = 1,
        }

public enum SubscriptionType
        {
            Basic = 1,
        }

When i run the migration it gives me this warnings: "The foreign key property 'GroupSubscription.SubscriptionId1' was created in shadow state because a conflicting property with the simple name 'SubscriptionId' exists in the entity type, but is either not mapped, is already used for another relationship, or is incompatible with the associated primary key type. See https://aka.ms/efcore-relationships for information on mapping relationships in EF Core."
