Hi All,
I am working on WPF project in that i am facing the build error is "

The type cannot be used as type parameter in the generic type or method wpf

"

I had created one wpf window the code is below

public partial class LicensingForm : Window,ILicensingForm
{
}

Here i am inhering the ILicensingForm class and
the ILicensingForm code is below

public interface ILicensingForm
    {
        Control ConfirmLicenseButton { get; }
        Control ConfirmationCodeInput { get; }
        Control EmailAddressInput { get; }
        Control RequestLicenseButton { get; }
        Control Status { get; }

        event FormClosedEventHandler FormClosed;

        void Close();
        void ShowMessage(string message);
    }

And i am trying to call that window in some other class(mainModule).

internal static class MainModule
 {
public static void RemoveLicense()
  {
      using (var licenseController = new LicensingFormController<LicensingForm>())
      {
                licenseController.RemoveLicense();
      }
     }

}
Here iam getting error in this line LicensingForm only.

new LicensingFormController<LicensingForm>
