> Subpar tooling outside of Windows (I'm looking at you C# Dev Kit)
JetBrains Rider is excellent and runs on Windows, Mac and Linux. It has a few Windows only features but nothing important for me, it's the best IDE for C#/.NET you can get on non-Windows platforms imo. And it's free for non commercial use.
I've worked with .NET for over 10 years and we built our startup on top of it. Here are my thoughts: Pros:
* Stability
* Very decent standard library
* Good balance between productivity and robustness
* Great package management
* Extremely easy to upgrade, so essentially free goodies (performance) every year or so
Cons:
* Very MSFT dominated (obviously)
* Subpar tooling outside of Windows (I'm looking at you C# Dev Kit)
* C# has way to many features, it feels bloated
* Culturally, it feels like .NET devs are less "passionate" about their work
* The freaking stigma of being a .NET dev: you will never be as cool as the guys who work with Node/Python/whatever
Edit: Also I'd like to add EFCore as one of the pros of the ecosystem. Hands down the best ORM. Others don't come close.
