IntelliSense alternative using SSMS 2012 in a contained database as a contained user?
I really don't think this is a problem with Management Studio, just that the user the tool has to act on behalf of does not have the permission to pull the metadata required to support IntelliSense. So I doubt other tools will fill the need. Your choices are:


Try other tools like SQL Prompt and SQL Complete
Use a server-level login with adequate DB privileges for development (vs. application runtime)
Live without IntelliSense


Hopefully they will fix this problem at some point. Even my Connect item incorrectly blames the UI when the problem is with the permissions (not) granted to the contained user.
