Description buasdjasid 2012-06-11 21:59:08 UTC
Hi, I'm trying to complete the basic tutorial here: http://monodevelop.com/Stetic_GUI_Designer

When I get to this step: "Click on the "Click here to add a new handler" next to the "Activated" signal and type "OnOpen" into the entry and press enter." I get an error with the following:

"System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.NotImplementedException: The requested feature is not implemented.

I downloaded MonoDevelop and MonoFramework recently. MonoDevelop is version 3.02 and the Framework is :"MonoFramework-MRE-2.10.9_11.macos10.xamarin.x86.dmg" I'm using Mac OS X 10.6.8
Comment 1 Mohit Kheterpal 2016-01-08 13:02:10 UTC
Today I have followed steps provided in tutorial http://www.monodevelop.com/documentation/stetic-gui-designer/ and observed that it does not throw exception when I "Click on the "Click here to add a new handler" next to the "Activated" signal and type "OnOpen" into the entry and press enter."

It would be helpful, if you check this issue at your end with latest stable builds. And if its still occurring then please provide the IDE logs (Help->Open Log Directory->IDE Logs).

Comment 2 Kirill Osenkov 2017-05-15 23:19:40 UTC
Since this issue is over 5 years old and we have evolved significantly since then, resolving as not reproducible. If you still have problems with the latest version of MonoDevelop please feel free to open a new bug. Thanks.
