The layer is in WGS84 projection and it has several features.<BR /><BR />When I add the layer to the active map using ArcCatalog, the layer displays correctly and the layer has the correct extent envelope displayed in the layer properties. I can right click on the layer and choose "zoom to extent" and ArcPro does indeed zoom to the layer.</P><P>But when I add the layer to the map using the following C# code the layer gets added to the map and displays OK, but the extent defaults to the maximum range of WGS84 (-180, 90, 180, -90).&nbsp;</P><LI-CODE lang="csharp">uri = new Uri("file:///C:/mydata/mygeopackage.gpkg/main.vwReaches") Layer layer = LayerFactory.Instance.CreateLayer(uri, parent as ILayerContainerEdit, 0, "my layer");</LI-CODE><P>&nbsp;</P><P>When I right click on the layer and choose "zoom to extent" ArcPro blinks and shifts slightly, but does not zoom to the correct extent.</P><P>Both methods produce identical layers in ArcGIS Pro.
