On biulding a project created following the instaructions in the README, I recevie the following warning. The build does succeed, and produces a runable Wasm.

I asked on the .net Discord channel: https://discord.com/channels/143867839282020352/1141126727028985877/1304582707287818314

The first one CSC : warning CS8784: Generator 'VtableIndexStubGenerator' failed to initialize. is used for COM and only used in CI so will not cause any issues.

The second one CSC : warning CS8784: Generator 'LibraryImportGenerator' failed to initialize. Would be an issue if you used custom marshallers or anything with [LibraryImport] in user code.

It maybe that this might be because the versions of the native-aot-llvm compiler are miss matched with the .net version you are using, i.e. the .NET SDK version used is 8 and the native-aot-llvm is build against 9 (or now 10)
