    sqlplus connects from client - Add Connection from with VS2010 fails


      Just installed today Oracle 11g Express Edition on server Oracle11g.
      And on a W7 VM installed VS2010 with ODP.Net

      My tnsnames.ora:
      XE =
      (ADDRESS = (PROTOCOL = TCP)(HOST = Oracle11g.domain.local)(PORT = 1521))

      With sqlplus i can connect to the server, but "Add Connection" in VS2010 fails with "ORA-12154: TNS: could not resolve the connect identifier specified".

      Can someone give me a hint?
