I have no idea about most .NET developers. At my current job (a public software company in US with thousands of employees) it's up to engineers to decide when to upgrade. We upgraded our main monolith app to .NET 10 in the first week.
I've been using .Net since late 2001 (ASP+) including in govt and banking and rarely have had issues getting timely updates for my local development environment, and in the past decade it's become more likely that the dev team controls the CI/CD environment and often the deployment server(s).... Though I prefer containerized apps over bare metal deployments.
