Improve experience for data binding and graphical interfaces

[ajcvickers]

EF Core is designed to work well with data binding scenarios, such as when used with Windows Forms or .NET MAUI. However, connecting the dots between these technologies is not always easy. For EF7, we plan to improve the experience with both work in EF Core and in Visual Studio to make it easier to connect the dots.

Hi @bricelam, I'm wondering whether or not there are any thoughts yet as to how you might accomplish this from a high level?

This is something I need now and it would be great to try and align what I'm implementing with what you're building. Is it just going to be a case of the proxy exposing INotifyPropertyChanged?

The primary work for this issue is to re-enable the Visual Studio tooling to work in more-or-less the same way it used to on .NET Framework.

Our WPF tutorial provides good guidance for databinding in XAML-based frameworks. We'll probably use that as the foundation for thinking about data binding in MAUI and WinUI. See also dotnet/EntityFramework.Docs#2541

Update: verified that WinForms and MAUI work well now. Walkthrough for WinForms has been completed. MAUI demo created and presented; convert to walkthrough tracked by dotnet/EntityFramework.Docs#3984
