My application sits on the same server as my database server so I wanted to test the performance of named pipes versus TCP/IP. I can't figure out how to get the application to connect VIA named pipes though.

This is the connection string I'm currently using for TCP/IP:
Server=127.0.0.1\SQL; UID=user; PWD=password; Database=testdb; Connect Timeout=5000; MultipleActiveResultSets=True; pooling=false

How would I change it to use named pipes?
