MonoMac apps do not run/debug with the current target runtime.
IIRC this is a regression, we used to use an env var to pass the runtime to the launch script.
MonoDevelop running on 2.10.9 with 3.0.3 installed works just fine. When MonoDevelop runs on 2.10.11 I get the error above.
fixed in git
Thank you. Does this effect Xamarin.Mac too? This is an active project so I'm hoping to get up and running as soon as possible.
Yea, it'll affect Xamarin.Mac, too.
Here's the latest internal build that you can use in the meantime:
Unfortunately I'm getting exactly the same thing with this build. I start debugging and get:
System.TypeLoadException: Could not load type 'System.Runtime.CompilerServices.ExtensionAttribute' from assembly 'Cirrious.MvvmCross.Mac'.

That's running with 2.10.11. Are you certain your target runtime is set to 3.0.x ?
Created attachment 3446 [details]
Created attachment 3447 [details]
I have attached 2 images.
If I create a new MonoMac or XamarinMac project and add the line below (target set to 3.0.3) I can reproduce the error straight away.
public override void FinishedLaunching (NSObject notification)
mainWindowController = new MainWindowController ();
The default target runtime can be overridden for a solution - Check the Project -> Target Runtime menu.
Today we have checked this issue with following environment:
X.S 4.0 - 2be9833ca58a68b3d64be96a40ab7e149647fed1
Mono 3.0.5 (master/5079328)
And we are successfully able to run/debug monomac application.
Changing the status to Verified.
