Hello,
Sorry, if it is not a real issue, but it would be great to see some UWP love with Cognitive Services. I have seen the UWP feedback back in 2017 in UserVoice https://cognitive.uservoice.com/forums/430321-bing-speech-api/suggestions/18440209-support-for-windows-10-uwp-in-bing-speech and it was marked Under Consideration. I believe UWP is something important to support.
Thank you
