My collegue asked for MeasureAction alternative in v100 SDK. Does it exist ? It was VERY usefull function, but we can't find it...
It looks like SDK.v100 got some serious functionality degradation since 10.2.2 version. No Clusterer, no MeasureAction, no esri:Navigation, no esri:ScaleLine and many others...
Measure and ScaleLine (ScaleBar) are coming soon - in fact you can start working with them right now in the v100 toolkit branch: GitHub - Esri/arcgis-toolkit-dotnet at v100
Clustering support is on the roadmap.
Please can you provide more details on what type of navigation control you would like to see? Your feedback will be used in our design process.
