[NativeAOT] How to reduce size of published shared library?

[Symbai]

I was trying out nativeAOT following this guide but I'm using a new empty .NET 5 dll project. The output size were 4.5mb for literally NO code at all.

Then I was trying to add some lines:

<PropertyGroup>
	<IlcDisableReflection>true</IlcDisableReflection>
	<RootAllApplicationAssemblies>false</RootAllApplicationAssemblies>
	<IlcGenerateCompleteTypeMetadata>false</IlcGenerateCompleteTypeMetadata>
	<IlcGenerateStackTraceData>false</IlcGenerateStackTraceData>
	<IlcDisableUnhandledExceptionExperience>true</IlcDisableUnhandledExceptionExperience>
	<IlcOptimizationPreference>Size</IlcOptimizationPreference>
</PropertyGroup>

This reduced the size from 4.5mb to 1mb. But imagine that its an empty project, it's still waaaaay too big. With C++ or Pascal I'm within 100kb area.

Is there more I can do to reduce the size or is it expected to be 10 times larger than other AOT compilers?

Yes, this is what you can get in the ballpark. We do not plan to work on reducing .dlls down to 100kB as part of this experimental project.
