Replace obsolete ITemplate.MasterTemplateAlias with LayoutTemplateAlias - #1003
Merged
Conversation
MasterTemplateAlias is obsolete in Umbraco 18 (CS0618, scheduled for removal in Umbraco 20) and is a pure rename forwarding to LayoutTemplateAlias, so this swaps all call sites over to clear the build warnings. No behavioural changes. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

What
Replaces all uses of
ITemplate.MasterTemplateAlias/ITemplateContentParserService.MasterTemplateAlias(...)with their non-obsolete equivalent,LayoutTemplateAlias.Why
Both members are marked obsolete in Umbraco 18 (
CS0618), scheduled for removal in Umbraco 20, and were producing build warnings.How
Confirmed via the decompiled
Umbraco.Cms.Coresource thatMasterTemplateAliasis a pure rename — a default-interface-member / property that simply forwards toLayoutTemplateAliaswith identical type, nullability, and semantics. All uses here were read-only (getters / method calls), so the swap is a direct drop-in replacement.Files touched
uSync.Core/Serialization/Serializers/TemplateSerializer.cs—item.MasterTemplateAlias→item.LayoutTemplateAlias(export, level calculation, parent lookup).uSync.BackOffice/SyncHandlers/Handlers/TemplateHandler.cs—_templateContentParserService.MasterTemplateAlias(...)→.LayoutTemplateAlias(...).uSync.AutoTemplates/TemplateWatcher.cs—template.MasterTemplateAlias→template.LayoutTemplateAlias.Notes for reviewers
MasterTemplateAliasCS0618warnings are gone.CS0618warnings remain (HtmlLocalLinkParserlegacy methods inSyncLocalLinkProcessor.cs, andISyncActionService.UnpackImportFromStreaminuSyncManagementService.cs) — intentionally out of scope for this change.🤖 Generated with Claude Code
