I use Final release of FGDBAPI.- The Geodatabase::CreateTable can't create featureclass using the XML that exported from GetDefinition. The error code is -2147467259 and the description is "General function failure".
- The XML that exported from GetDefinition does not contain WKT and WKID tags under SpatialReference tag. There isn't way to get a spatial reference information from FGDB except using ArcGIS.
- When a featureclass is created using XML with the minimum spatial reference definition, a spatial reference does not equal to the default values of ArcGIS Desktop.
