Pinch and Zoom with Appium and appium-dotnet-driver

Appium version 1.4.0.0
Appium Dotnet Driver version 1.2.0.8
Selenium Webdriver version 2.44.0.0
Android device version 5.0.1

I have created a driver object.

“AndroidDriver androidDriver = new AndroidDriver(remoteAddressUri, capabilities, TimeSpan.FromSeconds(TimeOutValue));”

I will not be able to create an instance for AppiumDriver, since it is an abstract class and also the AndroidDriver class inherits the AppiumDriver class.

There is no androidDriver.pinch and androidDriver.zoom methods.

Please let me know, what I need to do in order to achive pinch and zoom on an android mobile devive.

Thank you.
