Which .Net wrapper are you interested in?
I have tested the .Net wrappers only on Windows. For Android and iOS it is necessary to compile the library and make the wrapper to load/use it.
Some of the wrappers use the system SQLite library and we can just make it use the modified one, containing LiteSync. Others, like System.Data.SQLite, include the pre-compiled library but only for Windows (32 and 64 bits).
I will need the help of some .NET or Xamarin developer to create the binaries for Android and iOS.
To check if the wrapper contains LiteSync we can run the "PRAGMA sync_status" command. It will return a JSON document if LiteSync is present and an empty response if not present.
