The development tooling is great for small projects and breaks down a little as project size grows, while the automation and deployment tooling is middling-to-bad in my experience. The parent post is right about NuGet and MSBuild both being pretty ponderous compared to the myriad of package management and build solutions for various frameworks in the OSS world, and deployment for wider-scale systems is falling behind the K8s/containerized state of the art as well.
