Xamarin iOS debugger not hitting breakpoints

问题:

Yesterday morning as I started working on a Xamarin iOS application when my debugger stopped working. I can place breakpoints but as soon as the application starts the breakpoints become hollow like a red donut. I've rebuilt/cleaned project multiple times, I've also wiped obj/bin folders and nothing seems to work. I can't hit breakpoints.

This doesn't happen to all my classes, it looks like it applies to classes where an async function is used however this isn't always the case.

I also get a message in my debugger window which may have only started showing since this bug.

Xamarin.iOS: Successfully received USB connection from the IDE on port 10000, fd: 7 Xamarin.iOS: Processing: 'start profiler: no' Xamarin.iOS: Profiler not loaded (disabled)

I'm using Xamarin Studio 6.0.1 Build 9 Indie

I have found solution related to this issue: https://stackoverflow.com/a/34211506/4627978.

Also be sure, that you set Debug configuration in Xamarin Studio (not Release, AppStore, etc.) and enable debugging in Project Options > Build > iOS Debug > Enable debugging

After all this don't forget Clean/Rebuild.

I had this same problem and I got it working after changing the iOS project property Linker Behavior to Don't Link.

Make sure you have the iOS SDK updated to what you have in Xamarin.
