Address coding guidelines feedback - private modifiers already removed

[Copilot]

Stacked PR to address review feedback on #14 requesting removal of private modifiers from SegControlTest2.xaml.cs per project coding guidelines.

Status

No changes required - the requested modifications were already implemented in the base branch (Refactors) via commit 0dba733.

The file samples/SegmentedControlSamples/SegControlTest2.xaml.cs currently omits private keywords on fields and methods, complying with the guideline: "We do not use the private keyword as it is the default accessibility level in C#."

Verification

Current state (lines 7-36):

public partial class SegControlTest2 : ContentView
{
    Test2ViewModel viewModel;  // No 'private' modifier

    void SegmentedControl_ValueChanged(...)  // No 'private' modifier
    
    PlayerStatus playerStatus = PlayerStatus.Stopped;  // No 'private' modifier
    
    void SegmentedControl_SegmentTapped(...)  // No 'private' modifier
}
