By default, managed exceptions are ignored with the respective "Reset the list to the default settings" in the Exception Settings Window found in Debug -> Windows -> Exception Settings (CTRL + ALT + E)
For example in the OnCreate of a new Android Application:
throw new Exception();
catch (Exception ex)
This of course would be caught as it is thrown. However the debugger will not break upon it unless it was specified in the CLR options. So here's the respective scenario:
1) I do not have the CLR -> System.Exception Checkmark Checked - http://screencast.com/t/Uw7WsDr5j
I would then skip straight over the exception and continue running as normally. There is no break in the debugger and I see the following message in the console:
11-06 12:22:46.236 I/mono-stdout(28641): Failed
2) I do have the CLR -> System.Exception Checkmark Checked - http://screencast.com/t/NgaErHETv
The debugger would then break with the following popup - http://screencast.com/t/tdrdrbD0DX
Now here's the interesting part that I discovered...I'm not sure if it's a bug in our tooling or a bug with the new VS 2015 Exception Settings Window.
If I then Uncheck the System.Exception and try it again, I am running into the same scenario as #2. Which makes me think that the setting is not getting saved/reflected properly. However if I "Reset the list to the default settings" - http://screencast.com/t/NEESbyuSn3XS it now works and we'ere back to the #1 scenario.
I have also attempted to restart VS to see if it was an issue inside the IDE, but it does not seem to directly reflect those changes unless "Reset the list to the default settings" is clicked.
I should be able to correctly reflect my Exception Settings back and forth between the respective "Breaks" I would like to have. I should not have to "Reset the list to the default settings" to ignore managed exceptions.
1. Create a File -> New Android Project
2. Add the following code snippet to the bottom of the OnCreate inside the MainActivity:
throw new Exception();
catch (Exception ex)
3. Open up the Exception Settings Window found in Debug -> Windows -> Exception Settings (CTRL + ALT + E)
4. Click "Reset the list to the default settings" to ensure we start fresh
5. Run the application and see the observation as listed in scenario #1
6. Check the CLR -> System.Exception Checkmark
7. Run the application and see the observation as listed in scenario #2
8. Uncheck the CLR -> System.Exception Checkmark
8. Run the application and see the observation again listed in scenario #2
9. Click "Reset the list to the default settings"
10. Run the application and see the observation listed in scenario #1

As an additional followup:
It seems that you can also just "Remove an exception from the list" to get the desired behavior, but it still seems that the respective Checkboxes do not work when going from an "Active" state to an "Unactive" state.
I have reported this to Microsoft and they have reported it to Xamarin and they said they worked on a solution. It was in May. https://connect.microsoft.com/VisualStudio/feedback/details/1175453/exceptions-settings-windows
I have checked this issue and I am able to reproduce this issue given by description and steps. I am getting the same behavior as per comment 0.
Here is the screencast regarding same: http://www.screencast.com/t/6IN7jqPUU
Hence, I am changing the status of this issue as confirmed.
