Azure integration is not that great actually. For example .NET 5 support for Azure Functions is a huge breaking change with random issues, missing features and terrible IDE support (you have to launch it through CLI and attach to a PID printed out by the host process to debug a function, you could just debug 3.1 functions) - it's beta quality.

I find this a common theme with Azure support and .NET

What does it mean "the integration is tight"? Are we talking about good Azure libraries, or is there some runtime integration (e.g., a .Net orchestrator i.e., Kubernetes but for .Net applications rather than containers)? Or does it just mean that Azure is better than other clouds at running .Net because it's a first-class citizen where it's usually second-tier on AWS/GCP?

Alternative take, the Azure documentation is shit if you are not using dot net... but pretty good if that's your toolchain.
