While the help at ArcGIS Pro 1.3 API Reference Guide talks about a Tool or a Button, there is no topic on MapTool.
I have inherited the code from Community Samples, but there are no clue how to activate or mostly to deactivate the tool on OnSketchCompleteAsync or - better - when clicking the tool button again.
I can switch the tool appearance with IsChecked = false on OnSketchCompleteAsync, but - beside the fact that the tool button becomes not checked - the tool continue to be active on the page!
MapTool seems to be part of ArcGIS.Desktop.Mapping namespace, but neither this part of the SDK Help talks about it...
