Hi All,
with Entity Developer I click on 'New Model -> Code-mapped Entities -> Database First' and I have this error "Section DBProviderFactories can be appair only one time in every config file" (Note: this message is in Italian language; I have traslated);
If I click OK, the Setup Data connection propperties -> provider, is empty.

This behavior is caused by duplicated records:

<add name="BlackfishSQL Local Provider" invariant="Borland.Data.BlackfishSQL.LocalClient" description="Provider with inprocess database Server" type="Borland.Data.DataStore.DataStoreProviderFactory, Borland.Data.BlackfishSQL.LocalClient, Version=8.0.0.0, Culture=neutral, PublicKeyToken=91d62ebb5b0d1b1b"/>
<add name="BlackfishSQL Remote Provider" invariant="Borland.Data.BlackfishSQL.RemoteClient" description="Provider for connectivity to BlackfishSQL Server" type="Borland.Data.DataStore.DataStoreProviderFactory, Borland.Data.BlackfishSQL.RemoteClient, Version=8.0.0.0, Culture=neutral, PublicKeyToken=91d62ebb5b0d1b1b"/>
<add name="AdoDbx Data Provider" invariant="Borland.Data.AdoDbxClient" description=".Net Framework Data Provider for dbExpress Drivers" type="Borland.Data.TAdoDbxProviderFactory, Borland.Data.AdoDbxClient, Version=11.0.5000.0, Culture=neutral, PublicKeyToken=91d62ebb5b0d1b1b"/>

You should delete these lines from the file

C:\ Windows\Microsoft.NET\Framework\v4.0.30319\Config\machine.config

Ok, it works!
Thanks,
