Unable to delete azure database

Question

In the list of sql server database here:

https://manage.windowsazure.com/#Workspaces/SqlAzureExtension/Databases 

I select the database, and below - "Delete".

I press the delete button and it processes for a while and then says:

Failed to delete the database "system-50e5f905 -... etc."

I follow the link for more information, where it just says:

Invalid request

Additional Information

It seems that they are not related to each other by resources.

I was able to create and delete a new database.

I also connected to the MS SQL server management studio, and I can only see two named databases, not one of the databases that have the system-guid name system-guid for the name.

Answer 1

Databases with the system-SOME GUID name format can be federated.

Deletion (deletion) of the federation should be performed on the database management portal for the main database.

Caution: I do not know the consequences of refusing to federate, so make sure you have backup copies of the data that you do not want to lose, or study this further.

• From https://manage.windowsazure.com/#Workspaces/SqlAzureExtension/Databases
• Choose your primary database
• Choose "Create your SQL Database"
• Login
• At the top you see "server> [DB]> Tables", click [DB]
• Federations are shown on this page, and you can select them and "Drop Federation"

Answer 2

I deleted my database on Azure using "SQL Server Management Studio", right-click "Delete".

using the Code First command with the Update-Database command, it will be created.
