There are some possible solution.
But I received an error: "resource xml/network_security_config (aka com.companyname.test:xml/network_security_config) not found"
Where do I need to create a config XML file to have access to the Android manifest file?
I just want to linked xml file to the android:networkSecurityConfig in Android manifest.
If you want to test .NET MAUI app on localhost API and avoid issue for SSL cert, you can use a tool https://ngrok.com/
"ngrok" will put localhost on the internet - it's working for me
