Attempt to resolve native AoT warnings

martincostello · martincostello · commit 26c73febc4cf · 2025-11-24T12:02:17.000Z
Attempt to enable native AoT compatibility by using `[DynamicDependency]` to have the trimmer retain the static methods that are called.

Not yet tested in an actual native AoT application.
