Note: We're backporting this to 10.0/9.0 in aspnetcore. I assume you'll want to backport this too. |

Description
Adds
fetchTags: falseto all 11checkout:steps across 9 Azure Pipelines YAML files ineng/pipelines/. This prevents unnecessary Git tag fetching during repository checkout, optimizing CI pipeline initialization time.Customer Impact
None. Internal CI optimization only.
Regression
No. This is a performance optimization, not a bug fix.
Testing
YAML syntax validated. No functional changes to build or test processes.
Risk
Low. The
fetchTags: falseparameter only affects what Git metadata is fetched during checkout. Build and test logic remain unchanged. Tags are not required for any existing pipeline functionality.Original prompt
