For those Devs who are using Rider, and are not part of the JetBrains AI Assistant early access program, I highly recommend the Codeium plug in for JetBrains IDEs; it's free for individual developers, but I have no idea what it costs for teams (they keep that quiet, which I dislike intensely). The plus side of the Teams version is that it can be self-hosted, so no sending code outside your network.
It has far better IDE integration than the current CoPilot plugin, which I think may have been deprioritised while JetBrains implements their own branded AI Assistant.
