I've been trying to discuss this with someone from the LightSteamer technical department but it seems the technical support e-mail links directly to the sales team.
Currently there are 4 DotNet clients for LightStreamer.
- DotNetClient_N2 (Compiled with .NET version 3.5)
- DotNetClient_WinRT (Compiled with .NET version 4.6)
- WindowsPhoneClient (Compiled with .NET version 4.6)
- Silverlight (Compiled with .NET version 4.6)
None of these are compatible with Xamarin out of the box. Unfortunately because I don't have access to the source code I can't adapt any of them and recompile them as a PCL.
If someone from LightStreamer could port one of these to .NET version 4.5 in a PCL compatible format that would be ideal. I'm not sure if I have the technical expertise to implement my own generic HTTP solution.
