where may i get this file? thanks
Hi,
Can you provide more details about the type of application you're building or the type of ArcGIS SDK you want to work with?
For more details on getting the API included with ArcGIS Runtime SDK for .NET see: https://developers.arcgis.com/net/install-and-set-up/. This will enable you to build custom desktop and mobile apps for Android, iOS, and Windows.
Thanks
