The sample code demonstrates how to determine an Azure instance is in Production or Staging slot. Some customers like to use VIP swap to upgrade their roles (has no service down time), and usually they want to perform different operations depend on the instance’s current state in Azure Management Portal, for example, disable some events when application is in staging slot. But, as you know, RoleEnvironment class does not provide a property for this. In this sample, we use Windows Azure Management API for achieving goal, use “Get Deployment” service to get deployment ID and compare it with current instance.
You can find more code samples that demonstrate the most typical programming scenarios by using Microsoft All-In-One Code Framework Sample Browser or Sample Browser Visual Studio extension. They give you the flexibility to search samples, download samples on demand, manage the downloaded samples in a centralized place, and automatically be notified about sample updates. If it is the first time that you hear about Microsoft All-In-One Code Framework, please watch the introduction video on Microsoft Showcase, or read the introduction on our homepage http://1code.codeplex.com/.
