What feature in Azure Virtual Desktop allows for easy application delivery?

The feature that allows for easy application delivery in Azure Virtual Desktop is RemoteApp. This capability enables administrators to deliver individual applications to users instead of a complete desktop environment. Users can access these applications from various devices, making it easier for them to operate in different environments while still using the necessary applications.

RemoteApp was specifically designed to provide a seamless experience, ensuring that applications look and feel as though they are running locally on the user's device. This functionality is particularly advantageous in scenarios where users require access to specific applications without the need for a full desktop session.

The other options, while potentially related to application delivery, do not specifically focus on delivering applications in a streamlined manner as RemoteApp does. For instance, desktop publishing and application sharing mode might refer to broader methods of collaborating or presenting software, whereas Quick Deploy may refer to streamlined setup processes rather than the delivery method itself. Thus, RemoteApp distinctly stands out as the correct choice for easy application delivery in the context of Azure Virtual Desktop.
