I tried to import the updates for this module to test but wasn't able to.

Steps:

1. Clone repo and checkout this branch
2. Build project using "msbuild build.proj"
3. Import-Module C:\projects\azure-powershell\artifacts\Debug\Az.HealthcareApis\HealthcareApis.Autorest\Az.HealthcareApis.psm1
4. "New-AzHealthcareDicomService -Name julietestdsjs -ResourceGroupName julie-test-ps -WorkspaceName julietestwsjs -SubscriptionId c92938d4-52af-4699-9011-d8070f593db5 -EnableSystemAssignedIdentity" -> gets error "A parameter cannot be found that matches parameter name 'EnableSystemAssignedIdentity'."

Is there something I'm doing wrong, or are the changes for this PR not ready yet?

[Copilot]

The CSV file lacks a header comment explaining its purpose and structure. Consider adding a comment block at the top explaining what this file contains and how it's used in the build process.

[Copilot]

The generation date appears to be inconsistent with the PR metadata which indicates this is from August 2025. This might indicate the file was generated at a different time or the date format needs verification.

Thanks, it is working after the latest changes.

Tested for dicom service

• Create w/ -EnableSystemAssignedIdentity
• Update w/ -EnableSystemAssignedIdentity, $False to disable
• Update w/ -UserAssignedIdentity
• (after enabling private endpoint on the portal) Get dicom, validated private endpoint connections are correct

verified new JsonFilePath option of New-AzHealthcareApisWorkspace with Julie's help.
The rest of the changes look fine for Workspace CRUD documentation as well

[PTaladay]

Verified Fhir service creation and updates are working as expected.
