@ankushbindlish2 This looks good. The next step is to ensure that updating the packages in the powershell repo causes no issues. To do this you would (1) generate a digned build using the ps-common-sign Jenkins job; (2) Create a PR that puts the packages in toold\LocalFeed and updates the reeferences.; (3) Once this passes we will merge this ps-common PR, push a new set of common packages to nuget, and update the powershell pr to use the newly published common packages

Now that this PR is ready, we can do this [later this week], but you would need to update your module to actually use the new generated classes.

(1) generate a signed build using the ps-common-sign Jenkins job;

Jenkins job for this change : https://azuresdkci.westus2.cloudapp.azure.com/view/PowerShell/job/ps-common-sign/ yields https://azuresdkci.westus2.cloudapp.azure.com/view/PowerShell/job/ps-common-sign/317/
Az.StorageSync package for INT : https://azuresdkci.westus2.cloudapp.azure.com/view/PowerShell-Private/job/AzPsPri-Sign/58

(2) Create a PR that puts the packages in toold\LocalFeed and updates the references.;

• I had merged the changes in private branch to verify against INT environment. https://github.com/Azure/azure-powershell-pr/pull/437
• I presume toold is \tools\LocalFeed folder.
• Pull Request in Azure-powershell for referring localfeeds folder GraphRbac library Update Microsoft.Azure.Graph.RBAC library in local feeds folder azure-powershell#8893
• I will create another StorageSync PR referring this new library with re-recorded tests in Azure-Powershell repo.
