I have tried to make new widget for Operation-dashboard.
I found two type sample codes on the Esri's Github. WPF or Javascript.
Javascript samples look like new ones and esri's direction.
WPF samples does not seem to be updated since last year.
What kind of language do i choose for continuous usages?
Or, please let me know the differences between of WPF and javascript for Operation Dashboard add-ins.
Thanks.
