Creating a Storage account
Go to Windows Azure Portal.
Select New -> Storage -> Quick create and fill in your storage name. If you have multiple subscriptions (trial, paid, MSDN etc), be careful about which one you select.
After a few minutes, the storage is created and you can view its details. The storage account keys can be viewed and regenerated at Manage keys section.
Azure Storage Explorer
Download and install Azure Storage Explorer from their Codeplex project.
Add an account. The storage account name is the one you selected in storage creation.
Here’s a screenshot of Azure Storage Explorer displaying data about an Azure Table storage. You can noe easily view and edit eny type of Azure storage you want (table, blob, queue). Pair this with the excellent WCF Test Client and you are good to go!
