It's not. Base C# extension for VS Code is free and MIT[0], the closed component, that is a debugger, is free as well. There is an open-source alternative too, and what effectively all debugger implementations do is integrate with debugger API provided by .NET itself, which any new tool can hook into. At the same time, Rider uses its own homegrown debugger, that works even better and has nice time-travel capability.

In any case, I assume none of this has any use to you and the reply is posted simply as bad faith engagement, as it continues to happen whenever a piece of software that uses .NET is mentioned, because usually very few people within community have/take issue with the current (rich) tooling options.
Note how many comments here and in similar submissions completely ignore the topic at hand and instead try to criticize the points that their authors assume are an issue with .NET itself.
jdb is part of OpenJDK, and doesn't try to implement any such restrictions. Neither does gdb, for that matter.
But there is also a cultural difference. .NET libraries (including the standard library) are notoriously poor at implementing useful .ToString() overrides, because it's all designed to assume that you will use a debugger.
For comparison, Scala and Rust have cultures that emphasize printf-friendliness, and I rarely have to reach for a debugger at all. The difference it makes for my sanity is immense (as someone who wasted years on the shitshow that is .NET).
I spent way too long trying to get netcoredbg to work, and couldn't get it to do much of anything. Maybe it's less of a shitshow now? Given that your original reply wasn't "yeah nobody uses the MS debugger anyway", I somehow doubt it.

I mostly get annoyed when I see bad faith arguments that old problems are irrelevant because they're old, even if the problem has never actually been addressed.

I was able to successfully debug simple async code with it after installing the vsix, disabling the official one and restarting VS Code without changing any other settings.
So, for the trivial case it works. Submitted issues do indicate further compatibility problems like not supporting "Debug.Write*" methods (just use a logger or Console.Write* I guess?) or instability when bridging this extension to something that isn't VS Code.

This is the first time I hear someone tout print-based debugging as an advantage. The approach F# takes with printfn "%A" might be more to your taste. Otherwise, DebuggerDisplay and DebuggerTypeProxy are there for a reason, and I don't understand the case for not using a debugger. But if you really want to, there are many ways to make the output pretty. Making a simple '.Print()' extension method that will do indented JsonSerializer.Serialize is already a start. Records also come with default ToString implementation.
