How to make DataGrid.DataContext binding without freezing UI thread (C# WPF .NET 4.5)?

Question

.NET

Greetings to all, maybe someone has encountered such a problem, because I can’t solve it =( I did
everything according to the instructions: https://metanit.com/sharp/wpf/21.1.php
I do not bind data to a ListBox, as in the example, and to the DataGrid:

DataGridMark.DataContext = db.AccountsMark.Local.ToBindingList();

And at this moment I have a UI freeze.
And with further changes, like:

db.AccountsMark.Add(acc);
await db.SaveChangesAsync();

I get UI freeze too.
As I understand it, this is due to the fact that the binding is not done asynchronously.
Question:
How to bind asynchronously, or what to do so that there are no UI freezes when changes occur in db.AccountsMark

I recommend reading about MVVM, then you will understand how to make bindings correctly.
