Hi,
Thanks for pointing it out, I need to remove the SqlAzureConnectionString from config files, it is no longer used. At one time we had a separate data layer for SqlAzure but not long ago we dropped support for SQL 2000 and this enabled us to change our main MS SQL data layer so that it could work with SqlAzure so we no longer have to maintain a separate data layer for SqlAzure. You should just use the MSSQLConnectionString as you have discovered.
Best,
Joe
