In a recent video I set up an Azure Virtual Desktop (AVD) environment. That showed how to create an Application Desktop. The above video now shows you how to extend that environment to include a Remote App into the same user Workspace. The Remote App capability allows you to publish just a hosted application for users rather that a whole desktop. This makes it easy to host virtual applications for additional security and cost reduction.
