As you know, Azure Virtual Desktop (aka AVD, aka Windows Virtual Desktop) is the Microsoft solution to securely provide virtualized remote desktop virtualized on Azure.
To connect to an AVD session you need to use the remote desktop client (available here https://docs.microsoft.com/en-us/azure/virtual-desktop/user-documentation/connect-windows-7-10/?WT.mc_id=M365-MVP-7836) and then get your end-users to subscribe to a workspace.
Well, good news as this process can now be simplified by managing it with Intune/Endpoint Configuration Manager.
To do this, connect to your Intune portal (https://endpoint.microsoft.com/) to create a device configuration profile (for Windows) by accessing the Devices\Windows\Configuration profiles blade
Then create a new profile and select the Settings catalog for Windows 10 and later
After naming your profile, click on Add settings and search for autosubscription, then select Remote Desktop and check the Auto-subscription setting
Now, you need to add the AVD discovery URL: https://rdweb.wvd.microsoft.com/api/arm/feeddiscovery
Complete the device profile creation to assign it to your users or groups (recommended) using AVD.
That’s it, next time your users will sign in to the AVD remote desktop client they will get automatically subscribed to the workspace.
