I am trying to upgrading from 10.1 to 10.3.1 and getting an error "Interop type 'GraphicTrackerClass' cannot be embedded. Use the applicable interface instead."
I updated all the after updating all the References and an coding in Visual Studio 2013.
Here is the code that is failing:
'Initialize the GraphicTracker with the Map
m_graphicTracker = New GraphicTrackerClass()
I have tried just removing the Class like this:
m_graphicTracker = New GraphicTracker()
But then I get the error : Cannot embed interop type 'ESRI.ArcGIS.EngineCore.IActiveViewEvents_Event' because the source interface 'ESRI.ArcGIS.Carto.IActiveViewEvents' referenced by its ComEventInterfaceAttribute cannot be found.
