Hi, there are lots of examples of how to encode and get a streaming URL - for example look at the .NET samples here
https://github.com/Azure-Samples/media-services-v3-dotnet
But there is a difference between just progressive downloading an .MP4 file vs. streaming using DASH or HLS protocols. Which is it that you are interested in exactly?
You might want to check this example video showing how to use WebView with HLS for streaming.

Make sure to use the v3 API and examples above though to get the content streams.
