Switch database

I am using the latest Neo4j community version with .net. Since the latest Neo4j supports multiple databases, I created two databases GraphA and GraphB, where GraphA is the default database. Is there a way I can switch from default database GraphaA to GraphB. I know how to do it in the desktop by using ":use GraphB". But the .net driver does not allow me to do so. Thanks.
