How do the costs of running the .NET 7 codebase compare with running something open? I like .NET a lot, have worked with it a lot in the past. But when I tried my own startup, I picked node instead and don't really regret it. I'm getting back into .NET these days though at a new job again, and .NET 7 will be interesting to dive into. Still not sure I'd want to be that tightly-coupled to Microsoft subscriptions though. I'd tried getting a couple .NET projects off the ground back in the .NET 5 days or whenever .NET Core first became a thing. It was surprisingly expensive to run things in Azure, and to use tools too. So that played a role in me just picking node for my startup even though I'd have preferred to stick with C# and .NET if I could, so I could become an expert in those tools.
But yeah, it's definitely a huge plus to have access to .NET's massive standard library. The documentation is amazing, too. If the costs to run in Azure and to be tightly-coupled with Microsoft rthat way are reasonable for a lean/small startup or self-funded startup, then I may give it a shot again.
