I have an iOS project that refers MvvmCross assemblies. Sometimes when I try to navigate any class from MvvmCross framework I am getting an exception. The log says:
WARNING [2013-08-09 13:47:28Z]: Assembly browser: Can't find assembly: mscorlib, Version=184.108.40.206, Culture=neutral, PublicKeyToken=7cec85d7bea7798e.
WARNING [2013-08-09 13:47:28Z]: Assembly browser: Can't find assembly: monotouch, Version=0.0.0.0, Culture=neutral, PublicKeyToken=84e04ff9cfb79065.
ERROR [2013-08-09 13:47:28Z]: An unhandled exception has occured. Terminating MonoDevelop? False
System.AggregateException: One or more errors occured
I made several investigations, and it looks like the exception is raised only when I try to navigate MvxImageViewLoader class from MvvmCross, most other classes are navigated fine.
The same exception is raised when I try to navigate any extension method defined in MvvmCross.
I hope it helps.
I've problems reproducing the issue - I've tried the binaries from:
Can you give me the MvvmCross assembly that produces the crash ?
Try to navigate to any extension method. For example:
public partial class HomeView : MvxViewController
var set = this.CreateBindingSet<HomeView, HomeViewModel>();\
If you navigate this.CreateBindingSet(), you'll see "An error occurred dialog" with "System.AggregateException: One or more errors occured" inside.
There will be one more namespace in mentioned example:
Sorry, I missed it.
I just encountered this issue when trying to navigate, via CMD+D, to the ViewGroup type in Mono.Android.

In my case, I only observe is the AggregateException. The Assembly Browser opens, and Mono.Android is visible in the assembly list. However, the detail pane displays the root view of the Mono.Android assembly.
Should be fixed in 4.2
I just saw this in 4.2.
I am seeing this almost constantly in 5.3... and it's driving me a bit mad!
Just about every time I use "Go to Declaration" on a symbol that takes me to the Assembly Browser, I get an System.AggregateException; unless the Assembly Browser is already open, then it's fine.
That regressed - but is fixed in master.
Well, yeah maybe it's regression but in the last Xamarin Studio 5.2.1 (build 1) which is STABLE opening ANY library class definition in the Assembly Browser doesn't work. It just shows the old-good dialog with "System.AggregateException: One or more errors occured".
Isn't this a blocker?
I confirm what Ievgen says. Mac OS X, Xamarin Studio 5.2.1 (build 1), does not work with MonoTouch objects (AggregateException). I can manually navigate to monotouch.MonoTouch.UiKit.UiView class though.
Any info on when this might come to stable release? Because the alpha channel is so buggy it does not even open the solution and projects.
There is an easy work around:
Ignore the exception and navigate a 2nd time to the class - it should work..
No it's no blocker - it's not causing data loss and there is a simple work around.
I don't know when it'll land in stable - it's up to our QA process. We try to get out monthly releases.
