Using the 6.8.2.9 version, 64 bit, connected to Sql Azure and doing a Schema Compare gets "use statement is not supported to switch between databases"
The connection to Azure using the "Microsoft SQL Server" option in the connection window works for queries and other tools, like "Data Compare", all works. The problem is with the Schema Compare Wizard.
The connection to the Azure DB specifies the correct DB, the "USE" statement shouldn't be needed, and yet it complains about not supporting the "USE" function, so, the schema compare fails.
