We are currently performing a large migration to SQL Server 2012. It's been going well, but we have hit a problem testing an app. An app server is throwing an exception "This SQL Server version (11.0) is not supported". On further investigation an internal library (used potentially in a number of places) is found to be using Microsoft.SqlServer.ConnectionInfo 220.127.116.11.
Is this expected behaviour that this library can't access SQL 2012?
What are our options - the dev teams are nervous of installing a later version and changing this internal library to reference it (although tests have shown this works). Any simple ways around it?
