Description

This exception is thrown at network connection change after I subscribe to Connectivity.ConnectivityChanged event

"The application called an interface that was marshalled for a different thread. (0x8001010E (RPC_E_WRONG_THREAD))"

Steps to Reproduce

1. Create a new . NET MAUI App, framework .NET 7.0
2. Subscribe to Connectivity.ConnectivityChanged event
3. Connectivity.ConnectivityChanged += (sender, e) => { // never reach this point };
4. start the app in Debug mode and change network connection to see the exception. This exception does not crash the app.

"The application called an interface that was marshalled for a different thread. (0x8001010E (RPC_E_WRONG_THREAD))"

In Release mode it seems the only problem is if the event never get called.

If I change Windows target framework to .NET 6.0, event is called and it seems fine, but exception message is there

It works fine on Android.
