Convert C# console app into a UWP app (C# SignalR websocket, livestream of data)

I am building a UWP app using C# to visualise data from a stock market exchange. A stream of data is pushed by the exchange in real time using SignalR (websocket). Therefore this is NOT an API. I have a working code that runs correctly on a console application. The console app returns a stream of json strings on the console window. I will provide a .zip file with the Visual Studio solution of the working console app. The scope of the work is to convert the console app into a UWP app. The UWP consist of a single page with a textbox. The texbox shows the stream of json strings in real time. Note: there is no need to deserialise the json string at this stage.
