VB.net Axes.AngleAxis constructor problem

Hi,
I have a problem with Oxyplot using it in VB.NET.
I'm trying to plot a polar plot, so I have to define an AngleAxis and a MagnitudeAxis.
But doing it, I have the following build errors :
Erreur 2 '.ctor' est ambigu, car plusieurs genres de membres portant ce nom existent dans class 'OxyPlot.Axes.AngleAxis'
Erreur 3 '.ctor' est ambigu, car plusieurs genres de membres portant ce nom existent dans class 'OxyPlot.Axes.MagnitudeAxis'

I've found a similar discussion in the forum, but the solution seems to be to rebuild Oxyplot after having suppressed a line in the constructor file (*.cs). But the problem I have is that I use oxyplot as a built .dll, I don't have the source and I can't use the Nuget package since my development workstation isn't connected to the internet. So is there a way to get the last version of Oxyplot as a .dll ? In the same manner that it was with codeplex..

Thank you !

Nicolas
