Exception thrown on .NET 10 Windows when calling Permissions.CheckStatusAsync<Permissions.Microphone>() #32989
Description
Description
On Windows when targeting .NET 10, an exception is thrown when checking the microphone permission. It's trying to open the AppxManifest file but I don't know why. This doesn't happen when targeting .NET 9.
Steps to Reproduce
- Create a new .NET 10 MAUI project
- Set the debug target to Windows
- Write the following code (call it anytime after the MainPage
InitializeComponent();) and set a breakpoint on thecatch
try
{
var status = await Permissions.CheckStatusAsync<Permissions.Microphone>();
//.NET 9: status == "Granted"
}
catch (Exception ex)
{
//.NET 10: Throws error: Could not find file 'C:\...\bin\Debug\net10.0-windows10.0.19041.0\win-x64\AppxManifest.xml'.
}
F5. Notice the exception thrown. This does not happen when targeting .NET 9.
