Nullability of reference types in type of parameter 'sender' of 'void MainLayout.LocationChanged(object sender, LocationChangedEventArgs e)' doesn't match the target delegate 'EventHandler<LocationChangedEventArgs>' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'sender' of 'void MainLayout.LocationChanged(object sender, LocationChangedEventArgs e)' doesn't match the target delegate 'EventHandler<LocationChangedEventArgs>' (possibly because of nullability attributes).

Non-nullable property 'Path' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.

Non-nullable field 'hostname' must contain a non-null value when exiting constructor. Consider declaring the field as nullable.

Non-nullable field 'pathName' must contain a non-null value when exiting constructor. Consider declaring the field as nullable.

Non-nullable field 'queryString' must contain a non-null value when exiting constructor. Consider declaring the field as nullable.

Nullability of reference types in value of type 'List<string>' doesn't match target type 'List<string?>'.

Non-nullable field 'errorMessage' must contain a non-null value when exiting constructor. Consider declaring the field as nullable.

This async method lacks 'await' operators and will run synchronously. Consider using the 'await' operator to await non-blocking API calls, or 'await Task.Run(...)' to do CPU-bound work on a background thread.
