  Going through the instructions here: http://www.telerik.com/help/openaccess-orm/openaccess-tasks-postgresql-howto-connect-postgresql-database.html 
  
  I am using a PostgreSQL 9.1 database with 2.0.10 npgsql drivers installed to the GAC.
  
  When I point the connection string to a PostGIS enabled database I get this error:
  Unable to retrieve the database schema information.
  Reason: An item with the same key has already been added.
  
  If I point the connection string to a database without PostGIS enabled it works fine.
  
  Am I doing something wrong, or does the tool not support PostGIS?

  Hi Steve,
  
  looks like the postgis database installs it's meta data for function/procedures slightly different than normally postgres would do, f.e. the argument names are not visible.
  I filed a bug #141175 for this and the next version will contain the needed fix.
  I've added Telerik points for reporting this issue.
  
  Greetings & Happy New Year,
