Description Zoltan Varga 2013-04-24 13:44:38 UTC
Environment variables set in Project Options/Run/General are ignored when running/debugging xam.mac apps from xs. This makes debugging runtime issues pretty difficult since we cannot ask customers to set env variables to produce more logging output.

To reproduce:
* Set the env variable 'MONO_LOG_LEVEL' to 'debug' in Project Options/Run/General
* Run/Debug the app
* No debug output

Michael, can you shed some light into how this is supposed to work?
Comment 2 Mikayla Hutchinson [MSFT] 2013-05-15 20:08:40 UTC
The Mac execution handler needs support for the execution settings.
Comment 3 Miguel de Icaza [MSFT] 2013-05-15 21:23:44 UTC

Can you tell me what that is?  Is that a change that we need to make on Monomac/XamMac, or a change that needs to go into the addin?

options ignored in XamMac

environment variables are not sent to the app launcher when debugging, in this exemple, the MONO_GC_DEBUG is not set so the GC will have it's default behavior.

i'd like to add that parameters won't be sent to the program main, instead only something like -psn_0_340051 will be present in the string[] args array.
Comment 6 Sandy Armstrong [MSFT] 2016-01-04 16:45:43 UTC
As Alex mentions, command line parameters are also not passed. Although I get an empty args array in main, not a random argument.
Comment 7 Zoltan Varga 2016-10-13 19:06:37 UTC
Why is this 'enchancement' ? There is a UI, and it doesn't work. At least it should be disabled for xam.mac apps.
Comment 8 Chris Hamons 2016-10-13 21:06:46 UTC
I agree w\ Zoltan.

There is UI and it doesn't work.
