Description Mike Rowley 2015-09-10 17:59:15 UTC
I have run across an issue in Xamarin.Forms (both iOS and Android) where breakpoints are not hit in the App class if there are two App classes declared as partials.
    public partial class App : Application

I have attached a sample to illustrate the issue.

As it stands a breakpoint in the App class wont stop the debugger, however if you move the WelcomeString variable from the second App class (App.Clients.cs) and put it back in App.cs and rename the second App class the breakpoint will be hit.

I have tried this on other partials and the debugger stops as expected, it just seems to happen on App and only if there are actually two partials, simply declaring the only App class a partial doesn’t prevent the debugger from stopping on the breakpoint.

I am using VS2015 & Xamarin 3.11.893.0

I wasn't able to reproduce this issue on this day, with updated xamarin version (but your project and your XF version).
I guess the debugger had an issue that was fixed.
If you can still reproduce this problem, please reopen the bug, and we will need to reassign it to the debugger or runtime teams.

Warm regards,

the xf team
