Warning
This patch removes the suggested ClusterId functionality.
Suggested ClusterId Functionality
Prior to this change, the wrapper would generate a unique cluster ID based on the connection string and the cluster topology; however, in some cases (such as custom endpoints, IP addresses, and CNAME aliases, etc), the wrapper would generate an incorrect identifier. This change was needed to prevent applications with several clusters from accidentally relying on incorrect topology during failover which could result in the wrapper failing to complete failover successfully.
Migration
