I managed to fix it by deleting and creating my LocalDb instance. In my case it happened because I installed Azure SDK 2.2 over version 2.1.

The step-by-step to fix it:

  • Run sqllocaldb i to get your instance name:
     C:\Users\myUser>sqllocaldb i
     v11.0
  • Stop LocalDB instance:
    C:\Users\myUser>sqllocaldb p v11.0
    LocalDB instance "v11.0" stopped.
  • Delete your LocalDB instance:
    C:\Users\myUser>sqllocaldb d v11.0
    LocalDB instance "v11.0" deleted.
  • Create your LocalDB instance with the same name:
    C:\Users\myUser>sqllocaldb c v11.0
    LocalDB instance "v11.0" created with version 11.0.
  • Delete database files to allow emulator to recreate db files
   C:\Users\myUser\DevelopmentStorageDb22.mdf
   C:\Users\myUser\DevelopmentStorageDb22_log.ldf

That should fix your issues.

It looks like your windows account under which you logged in is not sysadmin in sqlexpress instance. Normally emulator uses database within sqlexpress with windows authentication.

The first time you run the Windows Azure storage emulator, an initialization process runs to configure the environment. By default, the initialization process creates a database in SQL Express LocalDB. So, please make sure that your SQLExpress service is running and your login have sufficient rights to use the database within SQLExpress. If you want to make use of a local instance of an SQL Server to be used by Storage Emulator follow steps listed at http://msdn.microsoft.com/en-us/library/windowsazure/gg433134.aspx.

What i am suspecting is that your LocalDB configuration with emulator is somehow corrupted or misconfigured.

Please follow the blog below to see if you can verify LocalDB instance is ready/working and it is used by Emulator:

If you still have problem the easiest method would be to uninstall SDK 1.7 completely and re-install which will fix any issue with your configuration rather the finding the problem and try to fix which could take longer.
