Anything else we should know about your project / environment?

This is a follow-up for #11879

We still need an option to resolve names with C#. We are still not able to write our own name resolver. For our .NET Core application on Windows, we just use c-ares and GRPCLB to resolve the names to the dynamic endpoint. On Android, we can't resolve the name right now at all since we are still not allowed to configure a specific DNS server on the devices in the customers infrastructure.

Are there any news on adding custom name resolvers to C-Core from C#?
