Description

I'd like to start a discussion around which trimming and AOT-related warnings we should enforce as build errors by default.

When targeting Native AOT or enabling trimming, there are several warning categories—particularly ILxxxx, WMCxxxx, and CsWinRTxxxx—that indicate potential runtime issues (e.g. unsafe reflection, dynamic access, unsupported marshalling, or trimming-incompatible patterns).

⚠️ Candidate Warnings

The following warnings should be enforced as errors:
WMC1500, WMC1510, CsWinRT1028.

However, I'm uncertain about the ILXXXX warnings, as there are too many of them (~40), and it's unclear whether we should include all of them.

IL2000;IL2001;IL2002;IL2003;...;IL2123;
IL3000;...;IL3057;

Research direction

Start with the warning categories and candidate list in issue #1992, focusing on WMC1500, WMC1510, CsWinRT1028, and the IL2000–IL3057 ranges. Determine which warnings should be enforced as build errors for trimming and Native AOT, then document the agreed policy; no file or test entry point is named in the issue.
