Description

Proposal: Support authoring unsealed types

Rationale

Currently WinRT only allows authoring sealed types. Adding unsealed type support will help adopters such as Windows Community Toolkit, Notifications component, and those who use inheritance. Authors otherwise may use class libraries to work around limitations with sealed classes.

Research direction

The proposal does not identify files, tests, or entry points, so begin by mapping how CsWinRT currently authorizes sealed WinRT types. Define the requirements for authoring unsealed types and verify that inheritance scenarios for the Windows Community Toolkit and Notifications component are supported without the stated class-library workaround.
