I am using 100.5 version of Esri RunTime Sdk for WPF/C#.
I would like to add Graphic objects into GraphicsOverlay, but i don't like to initialize Graphic class into loop.I initialize Graphic class outside loop and appear next error:
An item with the same key has already been added.
at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource)
at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add)
at Esri.ArcGISRuntime.Internal.AttributeDictionary.Add(String key, Object value)
How to solved this problem, because i have a lot of Graphics and i like to work my application fast.
