[build] Fix stabilized SDK workload manifest path#12192
Merged
Conversation
Derive the loose workload manifest folder from NETCoreSdkVersion so stabilized SDK installs use the product feature band rather than the prerelease package version. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> Copilot-Session: c61e4369-db2e-4ce1-894a-cda1324f6f58

Pull request overview
Updates the local workload manifest installation logic to derive the sdk-manifests feature band from the installed SDK version (NETCoreSdkVersion), fixing scenarios where “stabilized” SDK builds keep a prerelease package version that would otherwise point to the wrong manifest directory.
Changes:
- Add
_DetermineLocalSdkFeatureBandtarget to compute the SDK feature band fromNETCoreSdkVersion(including selective prerelease handling). - Update
InstallManifestAndDependenciesto use the computed feature band forlib\sdk-manifests\...lookup. - Add an explicit error when the feature band cannot be determined.
Keep malformed SDK versions empty so the feature-band validation reports a clear error instead of creating an invalid prerelease-only path. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> Copilot-Session: c61e4369-db2e-4ce1-894a-cda1324f6f58

PR #12180 exposed a mismatch in stabilized SDK builds:
MicrosoftNETSdkPackageVersionremained10.0.400-preview.0.26367.110, whiledotnet-installdownloaded an SDK whose actualNETCoreSdkVersionand product directory were10.0.400. The package-derived loose manifest path was thereforesdk-manifests/10.0.400-preview.0, but the installed SDK searchedsdk-manifests/10.0.400, sodotnet workload install android-depscould not discover the Android manifest.Derive the local manifest feature band from
NETCoreSdkVersion, matching the installed SDK'sSdkFeatureBandbehavior: round servicing patches to the X00 band, preserve the first two public prerelease components, and omit dev/ci/rtm prerelease labels. Emit a clear error when the feature band cannot be determined.
