Hello everyone, I'm converting application from ArcGIS pro to ArcGIS .NET SDK. When draw a line, I need to add a second line to make it like "shading effect", like image below. In ArcGIS pro, i use second SolidStrokeSymbolLayer with GeometryOffsetEffect, but it does not exist in ArcGIS .Net SDK. So how to do it in ArcGIS .NET SDK? I don't want to add second graphic. Any plan to add GeometryOffsetEffect in near future?
