Spent the weekend going through the .NET 10 release notes properly instead of just skimming the changelog, and a few things actually made me stop and re-read twice. First, it's an LTS release. After years of upgrading projects every time a new major dropped, having 3 years of support on this one is honestly a relief, less pressure to jump immediately, more time to plan the migration properly. Performance wise, the JIT and GC work is the part that impressed me the most. Nothing flashy to show off in a demo, but real gains in throughput and memory behavior under load, the kind of improvements you only notice when you're running something in production at scale and your server bill or your response times quietly get better. On the language side, C# 14 finally gave us the field keyword as stable, no more manually declaring a private backing field just to add a bit of logic in a property getter/setter. Small thing, but it removes so much boilerplate I've written a thousand times. Extension members are the other one I keep coming back to. Being able to extend a type with properties and static members, not just methods, opens up patterns that used to need awkward workarounds. Still going through the rest, but between the LTS support window and these runtime/language improvements, this feels like one of the more substantial releases in a while, not just a version bump.
