Sample showing issue

See repro:

Set a breakpoint in the "TestClass" in the PCL. Set "Enable device-specific builds" to true in the iOS project. Debug to a iOS device, note that the breakpoints will not hit (breakpoints hit in the iOS project though, such as in the AppDelegate class)

Change "Enable device-specific builds" to false and run again, note that the PCL breakpoints hit.

Note: this is the same bug as 42359 but I couldn't figure out how to re open a bug, and this is for VS2017 instead of 2015.

Comment 1 Brendan Zagaeski (Xamarin Team, assistant) 2017-08-02 21:54:44 UTC
Thanks for the test case and the additional observation about the effect of "Enable device-specific builds".

Overall the missing breakpoint behavior of the test case from Comment 0 matches Bug 56893, based on the confirmation and verification testing below.  I will accordingly mark this bug as a duplicate.




## Confirmation and verification status of the test case from Comment 0: verified fixed on the "Xamarin 15.3 release" preview

> GOOD: XamarinVS 4.6.0.295 (306f76a) + Xamarin.iOS 10.12.0.14 (d15-3: bf350ba5) + Visual Studio 2017 Preview version 15.3 Preview 7, "Xamarin 15.3 release" preview
> BAD:  XamarinVS 4.5.0.486 (fec6f88) + Xamarin.iOS 10.10.0.36 (d15-2: d2270eec) + Visual Studio 2017 version 15.2,                   "Xamarin 15.2.3 release"

Good results: The debugger pauses on the breakpoint as expected.

Bad results: The debugger does not pause on the breakpoint.
