I have a process that
- extracts a shape file from a zip file
 - opens the shapefile with OpenAsyc
 - validates the shape file
 - extracts data
 - cleans up
 
The clean up is failing because the shapefile is not being release/closed when it goes out of scope.  It doesn't look like ShapeFileTable (or FeatureTable) implement IDisposible so is there another way to release this resource?
Thanks
