The root cause of this is that here:
we are not getting the right path for bundled XM applications.
I'm not sure the correct fix, but it might involve mono changes.
If you are willing to traffic in implementation specific hacks, this appears to "workaround" the issue
by using reflection to "do the right thing".
I'm thinking this was caused by https://github.com/mono/mono/commit/c1a732c45276e2273ce295bac99cf3fb920b772b
No, ^ was in C8 but this exception was against C8 so can't be it.
Does Xamarin.Mac need to pass in a different config file (we'd need an API to do that, see my comment on https://github.com/mono/mono/blob/master/mono/metadata/icall.c#L7178) above?
is this a bug/behavior change in mono?
As a workaround, set the MONO_CFG_DIR to a directory with a readable machine.config.
This is not a regression, AFAICT, as this behavior exists for quite some time.
Please retest after 84e9975e41f48e2444d233eda64112377856276c.
Add this to additional mmp arguments:
--machine-config="" # Yes, two double quotes w\ nothing in it
When we bumped to latest, we should have picked up mono's "real" fix.
My commit just adds a backup option in mmp to work around it \ other use cases that require the file.
Sorry for not being clear.
Could you zip up your bundle and build log and attach?
.app file https://www.dropbox.com/sh/yqaj8y7tpv9xicj/AACoUf1BoTXgLctE0Sn-GFnLa?dl=0 and I have also upload full test project https://www.dropbox.com/s/ugysnb5lnzuf0cy/RemotingTest%202.zip?dl=0
Build output is : https://gist.github.com/Mohit-Kheterpal/712404eb089389be16b7d27717ecd796
The combination of my fix + mono's broke it. Looking into it...
Ok, we needed to bump mono again to get working after the first mono bump.
QA - Please retest against the very latest XM (3e1204278baa060c45f3a876492f91bd5582d3c5 or greater). Please note (which I forgot first time) that you will need to remoting.config's build action to BundleResource for things to work at all.
I have checked this issue after setting build action of remote.config's file to Bundleresource with latest build of MonoFramework-MDK-22.214.171.124.macos10.xamarin.universal_8be6ecc66f4c295a61dc5b5677794929731d05d6 + xamarin.mac-126.96.36.199_3e1204278baa060c45f3a876492f91bd5582d3c5 and observed that this issue has been fixed.

I have checked this issue with latest master build and observed that it is working fine after changing Build Action to BundleResource of remote.config's file . Here is the screencast for the same: http://www.screencast.com/t/uaLYLVfFC7
