I was just exploring Azure Toolkit 1.4 and when I ran the application I got the following error. Following post shows the way to resolve this issue.
Actually Windows Azure storage emulator by default works on a SQL Server Express instance which needs to be named ‘SQLExpress’. If you open the SQL Server Management Studio you can see the DevelopmentStorageDb20090919 database is created when install the Azure Toolkit.
We have to configure the named instance or default instance that we have registered in SQL Server (other than SQL Express)
1. Open Windows Azure command prompt from Program Files > Windows Azure SDK 1.4
2. For default Instance: write DSInit /sqlinstance:.
3. For named instance: write DSInit /sqlinstance:<named_instance>
For e.g if you have .\sharepoint, then write DSInit /sqlinstance:sharepoint
4. On running this statement it will popup the window and create the emulator storage database on the instance specified.
4. Now start the storage emulator and enjoy coding on Azure.
