Configuration for trimmed exe including SqlClient

[jods4]

I understand MS.Data.SqlClient does not support trimming yet.
Could the team share a build configuration that works in .NET 8.0 to include SqlClient untrimmed into an exe that is otherwise trimmed?

My goal is to publish a CLI tool that is self-contained -- and obviously trimmed for size.

Since I updated to latest MS.Data.SqlClient and .NET 8.0, no configuration I tried to exclude SqlClient from trimming works.
The only setup that works is completely disabling trimming, and insead of being ~30Mo the self-contained executable is ~180Mo now. That's terrible for a CLI tool.

Most things I tried usually end up in a TypeLoadException with "Unable to load DLL 'Microsoft.Data.SqlClient.SNI.dll'".

Thanks! This project is interesting to remove bits that shouldn't be there in the first place, but that's not really my question.

I'm ok (for now) with including all of MS.Data.SqlClient in my application, without any kind of trimming for this lib.

I'd like to still be able to use the dotnet trimming feature for the rest of my app.

There are documented options here:
https://learn.microsoft.com/en-us/dotnet/core/deploying/trimming/trimming-options?pivots=dotnet-8-0

And I've tried to go back to the previous default of partial for TrimMode, I've tried rooting MS.Data.SqlClient with TrimmerRootAssembly but it didn't work.

I'd like an example of a csproj configuration where .net 8 trimming works in a project using SqlClient (understanding that SqlClient itself can't be trimmed, but the rest should).
