Description Alexandre Pepin 2014-06-11 10:14:09 UTC
Since I upgraded to Xamarin 3, binding an objective-c property block doesn't compile anymore. 

I get the following error in the file Trampolines.g.cs : "<path>/BindingTests/BindingTests/obj/Debug/ios/ObjCRuntime/Trampolines.g.cs(36,36): Error CS1503: Argument `#1' cannot convert `string' expression to type `System.IntPtr' (CS1503) (BindingTests)"

See my attached sample

Today, I have checked this issue with:
XS 5.0(build 878)
X.iOS 7.2.3-39
Mavericks 10.9.2

I am successfully able to build attached sample successfully, without any error. Could you please provide XS info Using Xamarin studio->About Xamarin studio->Show details and

Diagnostic build output Using Xamarin studio->Preferences->Build->Log verbosity->Select Diagnostic from dropdown

Now Build the application then attached the Build output.

Comment 4 Alexandre Pepin 2014-06-11 15:00:26 UTC
It's seems it is the rebuild command that doesn't work. Only doing build works

To reproduce : try right clicking on projet and Rebuild. It also doesn't work right clicking on project and doing a clean and after a build. But doing a second build works after that. Really wierd

I can reproduce.

It looks like the generated code is incorrect.
Comment 6 Rolf Bjarne Kvinge [MSFT] 2016-09-23 16:59:26 UTC
This works now.
