I retyped the your demo sample in VB.Net and it builds okay with .Net-Runtime = Microsoft on my Win7-PC. Trying to test the debugging, I changed the .Net-Runtime to Mono (latest version, Mono 3.3.0 installed in C:\Program Files (x86)\Mono3.2.3) and got the error message:
Error building target GetReferenceAssemblyPaths: UNC paths should be of the form \\server\share.
This error also occurs when I build a new emtpy project from scratch!!
This seems to be a known bug
but I can not find any solution in the web so far.
Older versions of Xamarin are not available (“older versions are only shown for customers who have purchased them”) https:
Do you know about the problem? Any idea to get around it?
My idea was to use VisualStudio for editing and then download the solution from SVN into Xamarin for debugging.
