Xaml Hot Reload support

## Issue Description ##

I'm a WPF developer, I use pure MVVM architecture so I only use objects and DataTemplates, So I **don't** need the designer and drag&drop features of WPF. I only use XAML code and I use **hot reload** feature in Visual Studio while debugging to see the changes I make in the UI.
I'm a fan of VSCode and I use it for back-end development. I tried to load WPF project in VSCode (since I only need the code editor), and it worked perfectly, the syntax highlighting and suggestion is awesome, but unfortunately when I run debugging I can't see changes that I make immediately in the UI, I need to restart the application to see my changes.
I don't know if Hot Reloading is supported, If it's supported how to enable it?
And if it is not supported this would be a feature request.

N.B. I already tried **Watch** feature but it's not what I'm looking for, "Watch" restart the whole application after every change in code, I just need to refresh the UI without restart.

And thank you all for your great job

## Steps to Reproduce ##

Open WPF project -> Run Start Debugging -> Change XAML code & save.

## Expected Behavior ##

In Visual Studio Community you can change XAML code while debugging WPF application, and see your changes immediately in the UI.

## Actual Behavior ##

In VSCode when I make changes in XAML while debugging, nothing changes in the UI so I need to restart my WPF application to see my changes
