CA1811 warning for private imported properties in WPF

I have a public Controller class inside which I am using following properties

[Import]
private TransferRegionViewModel TransferRegionView { get; set; }

[Import]
private Lazy<IVoiceController> VoiceController { get; set; }

I am getting following CA warning:

CA1811 : Microsoft.Performance: 'TransferController.VoiceController.set(Lazy)' appears to have no upstream public or protected callers.

I am using VoicdeController property as : 

VoiceController.Value.CallTransfer(phoneNumber.PhoneNumber, true);

I referred this one - Properties private set; but don't understand if I need to set property internal or private.

Solution

  • It is "normal" warning when using MEF and Code Analysis together.

    Your property will be set at run-time by MEF container via reflection, hence, there's no any call of property setter, which could be proven statically by CA. The only way is to suppress this message by SuppressMessage attribute:

    [SuppressMessage("Microsoft.Performance", "CA1811:AvoidUncalledPrivateCode")]
[Import]
private Lazy<IVoiceController> VoiceController { get; set; }
