This is a working demo for the AvataaarsNet WPF Controller
To properly run the demo you can refer to the Releases tab (that version uses https://avataaars.io/ endpoint) or you can compile it yourself by adding a reference to this project: AvataaarsNet.
In any case you can also compile the .dll file from the linked repository (adjusting the endpoint if needed) and then adding that to the resources.
In this demo I use MaterialDesignInXAML for a better UI
Sometimes https://avataaars.io is not properly working or it may crash, be patience while I figure out a solution for that
