Is there a way to edit your code in order to address a different issue in a dll?

I am trying to compile an old Xamarin project on a real device. Unfortunately the project uses an old library (ShinobiCharts.dll) that is not supported anymore by their creators (and it was not opensourced after the end of support).

When I try to compile the project on a device (in the simulator works fine) now I get a new error with the latest Visual Studio for Mac (since we cannot compile it anymore Xamarin Studio for Mac):

Unified/MTOUCH: Error MT4116: Could not register the assembly 'ShinobiCharts': error MT4118: Cannot register two managed types ('ShinobiCharts.SChartSeriesCrosshairTooltipDrawerProtocol, ShinobiCharts' and 'SChartSeriesCrosshairTooltipDrawerProtocol, ShinobiCharts') with the same native name ('SChartSeriesCrosshairTooltipDrawerProtocol'). (MT4116) (ProjectName)

Is there a way to edit your code in order to address a different issue in a dll or a different workaround (some flag that we can pass to the compiler) or tool that works directly on the compiled dll in order to address this issue?
