Request

Description

Base class for all Package Manager asynchronous operations. Use this class to track the status and results of package operations, such as adding, removing, or updating packages.

• All Client (such as Client.Add, Client.Remove, and Client.List) return an object derived from the Request class.
• Check the IsCompleted property to know when the operation is done.
• Always check the Status property of the Request for a StatusCode of Success before accessing results to make sure the operation was successful.
