The CI build for develop is attached to every workflow run as OpenDBDiff-WinFormsGUI-* and OpenDBDiff-CLI-* artifacts (keep a run's download for 14 days).

Open DBDiff can synchronize

• Tables (including Table Options like vardecimal, text in row, etc.)
• Columns (including Computed Columns, XML options, Identities, etc.)
• Constraints
• Indexes (and XML Indexes)
• XML Schemas
• Table Types
• User Data Types (UDT)
• CLR Objects (Assemblies, CLR-UDT, CLR-Store Procedure, CLR-Triggers)
• Triggers (including DDL Triggers)
• Synonyms
• Schemas
• File groups
• Views
• Functions
• Store Procedures
• Partition Functions/Schemes
• Users
• Roles

dotnet build -c Release
dotnet test  -c Release

The test project targets net48 and net10.0, so the suite runs on Windows (both legs) and on Linux (net10.0). The WinForms projects are Windows-only; the schema libraries and the net10.0 CLI build on either platform. dotnet build needs the .NET 10 SDK.

1. Bump <Version> in Directory.Build.props on develop, so local builds agree with the release.
2. Tag that commit: git tag v0.14.0 && git push origin v0.14.0.
3. The release workflow builds, tests, packages OpenDBDiff_<version>.zip and OpenDBDiff.CLI_<version>.zip with a SHA256SUMS.txt, attests their build provenance, and opens a draft GitHub release with generated notes.
4. Review the notes and publish the draft.

The tag wins over Directory.Build.props: the workflow passes -p:Version=<tag>, which is what ends up in every assembly. To rehearse without tagging, run the release workflow manually with the dry run input - it builds and packages the artifacts but publishes nothing.
