Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
=================================================================
然而，当运行未附加到XS时，应用程序运行完美。知道问题是什么吗？
调用授权时代码崩溃..
try
{
Authorize (value); // I have a breakpoint here working... But it crashes during the call..
}
catch(Exception e)
{
_exceptionService.TreatException (e);
}
private void Authorize(object parameter)
{
var redirectUrl = parameter as string; //I have another breakpoint here, not breaking. Crashing before it.
(...)
ChangePresentation(new MvxRootPresentationHint(typeof (ThreadsListViewModel)));
}
谢谢。
