How do I correctly share the information between different pages in the PCL? Every page contains a few editors/textboxes and I need to save those information to an xml file. I've created a serializable class in PCL with a few objects to save the information that is typed in in the textboxes but I don't know where to call my implementation in which the file is created? Should I put it in App.cs or where exactly?
Another problem is that in PCL System.IO.FileStream is not supported. I need the app to run on UWP (Windows Mobile 10) and I don't get how I can access the System.IO.FileStream in the UWP specific class (where System.IO.FileStream is supported) and somehow bind it with the serializable class in PCL so I can use System.IO.FileStream?
I'm so confused and can't find any easy explanation, please help me.
