 > [!TIP]
 > To simplify user access rights during initial development and testing, Azure Virtual Desktop supports [Azure Dev/Test pricing](https://azure.microsoft.com/pricing/dev-test/). If you deploy Azure Virtual Desktop in an Azure Dev/Test subscription, end users may connect to that deployment without separate license entitlement in order to perform acceptance tests or provide feedback.
