> if your source code is based on newer .NET you have to update to a new version each year
.NET has a really refreshingly sane release life cycle, similar to nodejs:
- There's a new major release every year (in November)
- Even numbers are LTS releases, and get 3 years of support/patches
- Odd numbers get 18 months of support/patches
This means if you target LTS, you have 2 years of support before the next LTS, and a full year overlap where both are supported. If you upgrade every release, you have at least 6 months of overlap
There's very few breaking changes between releases anyway, and it's often in infrastructure stuff (config, startup, project structure) as opposed to actual application code.
