Description Ian 2014-11-18 18:11:10 UTC
Using the newest Beta bits.

VS 2013, iPhone 5s

I have a really simple page:

        public AccountsPage()
            Title = "Accounts";
            Icon = "account.png";

            BindingContext = new AccountsViewModel();

            toolbarItem = new ToolbarItem("?", "accounts.png",async  () =>
                await DisplayAlert("Hi", "Clicked me",null);
            }, 0, 0);

Adding the toolbar code causes the pageto explode when the toolbar button is pressed

You may not pass null to the Cancel argument. You will now get an ArgumentNullException
