Gmap.NET MacOS crash while initializing #148

Open iglaweb opened 2 years ago

iglaweb commented 2 years ago

MacOS Catalina 10.15.7. Attempted launching in Visual Studio and JB Rider – same outcome.

Exception is thrown on line this.mapMain = new GMap.NET.WindowsForms.GMapControl();

As far as I see, GMap control crashed in FastResourceLock.cs, CreateSemaphore and invokes native methods placed in kernel32.dll (see here). This dll library does not exist in MacOS. Seems, GMap did not add an implementation specific for MacOS and that's why it throws exception and works seamlessly on Windows.

I don't think GMap.NET.WindowsForms was ever intended to work cross-platform, but even the core package doesn't work cross-platform anymore (see the issue created before yours).
