Hello @Rajesh Angappan ,
This is a known issue in VS 2026 and it has been reported, and you can track its status on the Developer Community thread here: Ad Hoc Distribution for MAUI Android apps is missing in Visual Studio 2026.
In the meantime, while the team works on a fix, there are two workarounds available.
Command-line publishing
The recommended method is to publish your app using the command line. The pop-up you're seeing is guiding you toward this process, and it's a reliable way to distribute your application.
Downgrade Visual Studio
If you prefer using the Visual Studio interface for publishing, you can temporarily downgrade to Visual Studio 2022, where this feature is working correctly.
I hope this clarifies.
