Description

Fix #18207

Az.props doesn't need to be synced because in CI it is copied from main branch. See

azure-powershell/tools/PrepareAutorestModule.ps1

Line 79 in 175bb06

Copy-Item "$PSScriptRoot\..\src\*.props" $TmpFolder

I added a prop file named Az.Post.props in previous release. I'm wondering whether it should be added into the sync list as well.

@BethanyZhou yes, if that file is necessary for building the module on main branch, it needs to be synced to generation branch.

Seems like Az.Post.props is same with Az.props. It Will be copied from main branch. No need to add it in sync list.
