AdMob Test case

Steps to reproduce the issue:

1. Open the solution.
2. Select a device.
3. Go to Run/Start Profiling.
4. Tap on a UITextField.
5. Tap the other UITextField and the app will get frozen.



I'm trying to use the Profiler with a test case of bug #55246, but when I try to focus on TextFields, the app just gets frozen but the Profiler keeps working.

In the sample, if you comment the line `Google.MobileAds.MobileAds.Configure("ca-app-pub-YOUR~PUBID");` located in AppDelegate.cs and you run it again with Profiler, everything works as expected.

IOW, if Google.MobileAds dll is referenced somehow, the app gets frozen with Profiler when you try to focus on TextField.

Forgot to mention, I have Xamarin Profiler Version 1.5.4-19
Comment 2 Rodrigo Moya 2017-06-28 08:49:33 UTC
hmm, @alexrp any idea why this would affect the runtime profiler?
Comment 3 Rodrigo Kumpera 2017-10-11 18:06:03 UTC
Could you attach a native debugger and provide backtrace of all threads at the time of the hang?
Comment 4 Israel Soto [MSFT] 2017-10-11 21:14:28 UTC
I don't longer have a device with iOS 10.3 to be able to use the Profiler with it.

On iOS 11 the error seems to be fixed but on iOS 10 and lower, the issue is still happening.
