Hello,
In Visual Studio, Android Emulator is downloaded and installed online by calling the Android SDK Manager.
Therefore, if there is no network connection, you need to use an external Android Emulator for VS to debug.
Please refer to the following solutions:
1. Since Android Emulator is part of Android Studio, you could use the emulator by installing Android Studio on your working machine without the Internet connection. Please refer to Install Android Studio for more details.
2. If you're having trouble installing Google's Android Emulator, you could also use the new feature Windows Subsystem for Android™️ of Windows 11 to run Android Emulator on your machine.
By the way, the advantage of using Windows Subsystem for Android™️ is that there is no need to install additional software, and the disadvantage is that it cannot simulate some phone-like features.
Best Regards,
Alec Liu.
