Dear group, I would like to announce a Linq Provider for Postgres (i.e. a driver for C# 3.0 Language-Integrated Query - which is an O/R mapping layer). Here is the project page: http://code2code.net/DB_Linq/index.html Or go straight to the code: http://code.google.com/p/dblinq2007/ Limitations: a) You need to run from source, and b) it's not ready for production yet. Regards, Jiri George Moudry
