nope, it seems to be lacking several things.
I need to have a different value for local and for cloud
in the page you link it shows a snip of the UI is visual studio that has "Connection string" that is not a database connection it is an azure storage connection.
also I am using a database first / ef and in the new ef you can not pass a parameter for the name of the connection string. (the company dba folks do not want developers having code that creates tables and databases)
ef db first is a guess part of the problem, why did they not allow a connection string parameter in V6 ? they did in the older ones.
or I can't find an overload for new that has it exposed, the generated class file has call to the ef base class that has a parameter ..... will have to play around with the code and see what's going on.
also the azure walkthrough on setting up a cloud service is very light and does not spend much time on the details of setting up the publishing and configuring of a project.
I sit in the next room to the EF folks. I'll go ask :D
