===========================================

Is this something I’m doing incorrectly?

Thanks.

Thanks, logged as bugs://79261

bugs://79261 got closed with status fixed.

Just installed the latest beta for oxygene. I tried to add a window method to a WPF project by double clicking as described above, and still got the unhandled exception. Is the bug fixed in RemObjects Elements - 10.0.0.2247?

Thanks

Which version did you install? — .2247 is the latest beta build.

Hi Marc, .2247 according to the exe name, installed against an existing VS2015, then opened the pre-existing project, and tried to add a method to the main window.

Bob

bugs://79261 got reopened.

OK, gotcha. I’ve re-=opened the issue, thanx for letting us know it’s not fully fixed.

Confirmed fixed. Many thanks.
