I am working in UWP and I can't use the HttpListener
class from the System API. Is there a new feature in the Windows API?
is there a new feauture in the Windows API?
Not all .NET APIs are supported in UWP app. You could check .NET for UWP apps to see all supported .NET APIs in UWP.
In your case, you should be looking at: StreamSocketListener in Windows.Networking.Sockets Namespace. You could use StreamSocketListener to make a similar httplistener by yourself.
