[Spec, TODO] Define work for Forms/Device/Platform/Application

[PureWeen]

Define Application for MAUI

• Consolidate the xplat application and the native applications into a single class
• Create a better application concept for android that doesn't tie application to the activity
• Multi Window considerations
• How does this tie into [Spec] Microsoft.Extensions.Hosting and/or Microsoft.Extensions.DependencyInjection #24
• How can we expose platform level events? OnNewIntent etc...

Just noticed that we may need some features from the Activity (such as the bundle and Intent) to get data...

I'm glad to see Multi-Window in the list. I was surprised by the many gotchas for that scenario in X.F.
And the main culprit was Device.BeginInvokeOnMainThread(). Ideally, we should remove it, but even if we keep it, it must never be used inside X.F/MAUI. The proper pattern is to always pass the IDispatcher.

I found this issue by looking for existing issues for multiple window support before creating one. Thanks for calling it out!

I am an F# developer and have been investigating Fabulous for a desktop application, but since it is built upon Xamarin Forms, it does not support multiple windows, so it's basically unusable for desktop applications.

Would it be better to separate out multiple window support into its own issue? I think that is an absolute must have if .NET MAUI is intended to support desktop applications.

@bmitc i have found having tabs is an ideal way to do a modern MDI interface infact 10 years ago I built a WPF app where I used tabs to open items the users clicked on and it worked very well - much like a browser does...

Tabs are not an acceptable replacement for multiple windows for many applications.

I'd like to ask what consideration are there made for windows parity? As someone who depends on third party software that has us using DDE dynamic data exchange on Windows, which requires a WinForm application to be running. I would still like to get some of the benefits of building on Linux but target Windows.

We recently taken https://github.com/Specshell/specshell.software.ndde and made it work on net5.0-windows which is great but would be great for all our downstream application which are in private repos to be able to build on Linux machines on GitHub actions.

Mostly handled by #1965 and the rest by other various PR's and issues/specs

@Redth Do you know where the multiple windows feature is being tracked?
