export function in generated lib

[szhaomsft]

I saw a lot of function of dotnet are exported in static libs

is this by design?

We export these methods because of it was an easy thing to do, and it allowed us to experiment with splitting the compilation into multiple units.

I agree that it would be nice to have an option to keep these methods private if the library is compiled as a single native module file.

As a workaround you could create version script manually and pass it to linker useing CustomLinkerArg option in .csproj

  <ItemGroup>
    <CustomLinkerArg Include="-Wl,--version-script=$(ProjectDir)exports.map" />
  </ItemGroup>

Actulay version-script generation was added in PR #5154, but now there is no such logic

Majority of the exports listed above are gone now thanks to recent objectwriter changes. Let's use #7340 to continue the discussion on this.
