Bump Mgmt Base Version

Skill: bump-mgmt-base-version

Bump the base http-client-csharp dependency used by the management-plane generator (http-client-csharp-mgmt). This updates both the npm emitter dependency and the NuGet generator dependency, then rebuilds and regenerates test projects.

When Invoked

Trigger phrases: "bump mgmt base version", "update http-client-csharp in mgmt", "bump generator version", "update mgmt dependency".

Instructions

1. Determine the target version

Read the latest version of @azure-typespec/http-client-csharp from:

eng/azure-typespec-http-client-csharp-emitter-package.json

Look at the dependencies["@azure-typespec/http-client-csharp"] value. This is the target version.

2. Identify current versions

Check the current versions in these two files:

| File | Field | Purpose |

|------|-------|---------|

| eng/packages/http-client-csharp-mgmt/package.json | dependencies["@azure-typespec/http-client-csharp"] | Emitter npm dependency |

| eng/centralpackagemanagement/Directory.Generation.Packages.props | <AzureGeneratorVersion> | Generator NuGet dependency (used by Azure.Generator.Management.csproj via <PackageReference Include="Azure.Generator" />) |

If both already match the target version, no update is needed — inform the user and stop.

3. Update version references

Update both files to the target version:

• eng/packages/http-client-csharp-mgmt/package.json: Change the @azure-typespec/http-client-csharp version in dependencies.
• eng/centralpackagemanagement/Directory.Generation.Packages.props: Change the <AzureGeneratorVersion> value.

4. Run npm install

cd eng/packages/http-client-csharp-mgmt
npm install

This updates package-lock.json to resolve the new dependency version.

5. Build the emitter

cd eng/packages/http-client-csharp-mgmt
npm run build:emitter

If TypeScript compilation fails, examine the errors — they likely indicate breaking API changes in the base @azure-typespec/http-client-csharp package. Fix the emitter source code under eng/packages/http-client-csharp-mgmt/emitter/ accordingly.

6. Lint and format the emitter

cd eng/packages/http-client-csharp-mgmt
npm run lint
npm run prettier

If lint or prettier checks fail, fix with:

npm run lint:fix
npm run prettier:fix

These checks are required to pass CI. Always run them after any emitter code changes.

7. Build the generator

cd eng/packages/http-client-csharp-mgmt
npm run build:generator

This runs dotnet build ./generator. The Azure.Generator.Management project references the Azure.Generator NuGet package, whose version is controlled by AzureGeneratorVersion in eng/centralpackagemanagement/Directory.Generation.Packages.props.

If C# compilation fails, examine the errors — they likely indicate breaking API changes in the Azure.Generator package. Fix the generator source code under eng/packages/http-client-csharp-mgmt/generator/Azure.Generator.Management/ accordingly.

8. Regenerate test projects

pwsh eng/packages/http-client-csharp-mgmt/eng/scripts/Generate.ps1

This script:

• Rebuilds the emitter and generator (via Refresh-Mgmt-Build)
• Regenerates the Mgmt-TypeSpec test project under generator/TestProjects/Local/Mgmt-TypeSpec/
• Builds the regenerated test project to verify correctness

If regeneration produces file changes, they must be included in the commit.

9. Refresh the Emitter Version Dashboard

pwsh doc/GeneratorVersions/Emitter_Version_Dashboard.ps1

This regenerates doc/GeneratorVersions/Emitter_Version_Dashboard.md so the documented dependency chain matches the updated package.json versions. The updated dashboard file must be included in the commit.

10. Verify

• Run git status to see all modified files
• Ensure package.json, package-lock.json, Directory.Generation.Packages.props, Emitter_Version_Dashboard.md, and any regenerated test project files are included
• All changes should be committed together
