Hi,We're building a plug-in data source. The data is typical WGS1984 lat/lng data. In the plugin data source, we're creating the spatial reference with code similar to the following:var spatialReferenceFact = new SpatialReferenceEnvironmentClass(); shapeField.SpatialReference_2 = spatialReferenceFact.CreateGeographicCoordinateSystem(6326);
Problem is, when I try to drop the plug-in data source on a map, I get the following error:Error opening feature class. The specified WKID (factory code) or WKT (definition string) is not a Projected Coordinate System.
I'm curious why it's wanting a projected coordinate system. According to the docs, I should be able to use a Geographic Coordinate System with a plug-in data source. Any suggestions?
