Bump Mgmt Base Version

Skill: bump-mgmt-base-version

Bump the base http-client-csharp dependencies used by the management-plane generator (http-client-csharp-mgmt). This updates the Azure and compatible unbranded npm emitter dependencies and the Azure 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 Azure target version.

Determine the unbranded target version required by that exact Azure package version:

npm view "@azure-typespec/http-client-csharp@<azure-target-version>" dependencies --json

Use the returned @typespec/http-client-csharp dependency version. The management emitter imports the unbranded package directly, so its pin must match the Azure package's dependency to avoid loading incompatible copies of the TypeSpec library.

2. Identify current versions

Check the current versions in these two files:

If all three already match their respective target versions, no update is needed — inform the user and stop.

3. Update version references

Update the version references:

1. eng/packages/http-client-csharp-mgmt/package.json:
   • Change @azure-typespec/http-client-csharp in dependencies to the Azure target version.
   • Change @typespec/http-client-csharp in dependencies to the unbranded target version required by the Azure package.
2. eng/centralpackagemanagement/Directory.Generation.Packages.props: Change <AzureGeneratorVersion> to the Azure target version.

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 both base dependencies in package.json match the Azure package's compatible dependency chain
• 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
