Hi all! It's a great pleasure to say that Npgsql2 RC2 is released. From release notes: This version contains some fixes and updates for latest entity framework release. We are already in feature freeze and not so many things were added this time. Highlights include: Npgsql2 rc2 now supports .NET 3.5 sp1 with Entity Framework support. We support model generation by the command line edmgen.exe tool. This requires the Npgsql be registered in the provider section of machine.config. A lot of fixes were done on connection pool handling. Also, when running under Mono, Npgsql wasn't using connection pool. Now it is. We added some code to better handle threadabort when executing queries with Npgsql. It isn't perfect but is much better than with previous versions.
