**Description**

As of v5.2.41727.0928, the Windows desktop SDK contains [IMeetingParticipantsController.AskAllToUnmute](https://github.com/zoom/zoom-sdk-windows/blob/13acb5482b6421dcf42ec9144d390f9db78c0e01/h/meeting_service_components/meeting_participants_ctrl_interface.h#L278). The [C# IMeetingParticipantsControllerDotNetWrap interface](https://github.com/zoom/zoom-c-sharp-wrapper/blob/master/zoom_sdk_c_sharp_wrap/meeting_participants_ctrl_donet_wrap.h#L13) does not contain this method.

Given that calling `IMeetingAudioControllerDotNetWrap.UnMuteAudio(0)` is invalid in SDK 5.x (as far as I know), please could we have a wrapper for the AskAllToUnmute method?

**Which version?**

C# SDK wrapper v5.2.42037.1112.

Hey @jonskeet,

Thanks for using the dev forum!

I will forward this to the team to implement. However, the C# wrapper is not actively managed by Zoom, so a timeline is unknown. However, if you need this interface sooner, you can manually add it to the wrapper. Here is an example of how to do this: [Customized UI C# callback](https://devforum.zoom.us/t/customized-ui-c-callback/7155/3).

Thanks!  
Michael

It’s implemented in the C# version v5.5.12509.0330  
CZoomSDKeDotNetWrap.Instance.GetMeetingServiceWrap().GetMeetingAudioController().UnMuteAudio(0);
