.NET release support and upgrade planning
Use current SDK, runtime and lifecycle data to choose a supported release channel, plan upgrades and verify what your build agents should install.
Default for most production apps
Choose an active LTS channel when you value a longer support window and a predictable major-version cadence.
When an STS channel fits
Choose supported STS only when your team can plan the next major upgrade on its shorter lifecycle and needs the newer platform features.
Before adopting a preview
Validate CI images, package compatibility, deployment targets and a rollback plan. Preview status is not a production-support promise.
Channels to evaluate now
Start with the release type and support window, then open the channel page for exact SDK and runtime values.

Upgrade planning checklist
- 1. Pin the SDK deliberately. Use global.json when your solution or CI must use a specific SDK feature band.
- 2. Update CI and local tooling together. Compare dotnet --info output from a build agent and a developer machine.
- 3. Restore and test every target. Framework and package resolution can differ across multi-targeted projects.
- 4. Schedule before end of support. Track the published EOL date as a delivery constraint, not as a last-minute upgrade task.
