Just installed VS Ultimate 2013 version 12.0.30110.00 Update 1, then went to the Windows Azure site and created an account. Also downloaded and installed the Windows Azure 2.2 SDK.
I open visual studio and go to Server Explorer. I see Data Connections, Servers (my machine), and SharePoint Connections. I don't see a Windows Azure Node. I look under the tools menu and see Connect to Database, Connect to Server, Add SharePoint connection.
So I download VS 2013 Express for Web, I open it and see under the tools menu Connect to Database, Connect to Windows Azure. I open the server explorer and see Data Connections, Servers, Windows Azure.
Does the Azure functionality only exist in the Web Express version and not in the Ultimate 2013 version of Visual Studio?
