Efcore: EF Core platforms experience

[ajcvickers]

This an "epic" issue for the theme of improving the EF Core experience in various app models. Specific pieces of work will be tracked by linked issues.

---

We have good guidance for using EF Core in traditional MVC-like web applications. Guidance for other platforms and application models is either missing or out-of-date. For EF Core 5.0 we plan to investigate, improve, and document the experience of using EF Core with:

• Blazor
• Xamarin, including using the AOT/linker story
• WinForms/WPF/WinUI and possibly other U.I. frameworks

As with is likely to be many small improvements in EF Core, together with guidance and longer-term collaborations with other teams to improve end-to-end experiences that go beyond just EF.

Specific areas we plan to look at are:

• Deployment, including the experience for using EF tooling such as for Migrations
• Application models, including Xamarin and Blazor, and probably others
• SQLite experiences, including the spatial experience and table rebuilds
• AOT and linking experiences
• Diagnostics integration, including perf counters

WinForms/WPF/WinUI and possibly other U.I. frameworks

Does this include UWP?
