Windows Admin Center version 2211 is now in Public Preview!

Tang_Tianfeng The most up-to-date material is in the Developer Guide extension in the product itself, where there should be sample code for many of the angular components, among other things. If there is not sample code for the component you are looking to use, or you have any other questions pertaining to extension development, please reach out to the WAC team at wacextensionrequest@microsoft.com and we can assist you. 

Taomyn_352 Updates shouldn't cause this. Could you please file an issue on https://aka.ms/wacfeedback

Karl-WE WAC doesn't have a dedicated session but it's going to be featured in different ways around Ignite. I would recommend watching this session for an announcement 😉 Increase your business agility and resilience with the latest Azure infrastructure solutions (microsoft.com)

Sam_T We really, sincerely appreciate the feedback here. I want to start by assuring everyone that we continue to value and invest in Windows Admin Center every day and with every build that we create. I empathize with these concerns, and we are truly working hard to make Windows Admin Center an excellent tool to manage Windows Server and Azure Stack HCI. For full transparency, instead of addressing direct bugs at this time, we are working to address this from the bottom-up - i.e. answering the question "what is causing all these bugs to appear in the first place?". We're actively working on a thorough UI automated testing pipeline to prevent further bugs from being introduced. Once this is available, we'll systematically work through bugs and be sure that we are not introducing additional bugs in the process. Yes, progress seems slow right now, but we're working on some long-term investments that will make new features in WAC much easier to release, without introducing regressions.
