Like me, you probably work on multiple Windows Azure projects and have to deal with many Windows Azure Subscriptions.
Working in Visual Studio with many Windows Azure Subscriptions can be messy, overwhelming and error prone. Fortunately, Microsoft added a new feature that allows us to filter the Server Explorer in order to show only the resources for a particular Windows Azure subscription, only the resources that are hosted in a particular region, or both.
Released in August 2013 as part of the Windows Azure SDK, this feature really helps me make sense out of all the subscriptions connected to my Microsoft Account.
Filtering resources is achieved by right clicking on the Windows Azure node In Server Explorer and by choosing Filter Services.
Choosing Filter Services will show the Windows Azure Services dialog box. Select the Subscriptions and Regions that you want to display in the Server Explorer and click Apply.
