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
I agree, the functions story with .NET 5 is a right pain in the arse at the moment. I understand why it's happened, but I want my .NET 5 durable functions!
Azure functions are one small part of Azure. Im talking about Azure Dev ops for example which is deeply integrated in the tooling. Including source control/product backlogs/pipelines/testing etc.
