Create comprehensive documentation for the .NET MAUI Aspire integration #3071
Description
For .NET 10 we're adding an integration with Aspire. I want to add a comprehensive doc, one page for now, on how to get started.
Start by describing what it is and what people can do with it. What are the benefits or using Aspire with .NET MAUI? You can reference this page: https://learn.microsoft.com/en-us/dotnet/maui/data-cloud/local-web-services?view=net-maui-9.0 because this should become a lot easier for people. In fact, add a reference back from that page to this new docs page as well, but don't change anything else.
From there, describe how people can get started setting this up for their project. People need to add a MAUI service defaults project (dotnet new maui-aspire-servicedefaults) and the app host project and potentially anything for the web services they try to connect. Reference the Aspire docs where applicable.
Suggest good places for screenshots and describe what those should show.
Make sure to note that the functionality is in preview. Integration in Visual Studio 2026 is coming but not completely available yet.
Have a look at the sample code for that here: https://github.com/dotnet/aspire/tree/main/playground/AspireWithMaui this has the public API to be used. Also look at dotnet/aspire#12402 and lets make sure to include iOS and Android in this and make special note of the Dev Tunnels integration there.
Remember to update the TOC and put it in a place where it makes sense.
