Exception on Appium with c# .net

I think i have configured appium correctly. This is what I get when i click on the launch button:

I made a simple coded UI project with few lines to automate my hybrid android application:

namespace CodedUITestProject3
{
    /// <summary>
    /// Summary description for CodedUITest1
    /// </summary>
    [CodedUITest]
    public class CodedUITest1
    {
        public AppiumDriver driver;
        public DesiredCapabilities capabilities;

        [TestMethod]
        public void CodedUITestMethod1()
        {
            Console.WriteLine("Connecting to Opium server");

            capabilities = new DesiredCapabilities();
            capabilities.SetCapability(CapabilityType.BrowserName, "Android");

            capabilities.SetCapability(CapabilityType.Version, "4.1");
            capabilities.SetCapability("deviceName", "Android");
            capabilities.SetCapability("platformName", "Android");

            capabilities.SetCapability("appPackage", "com.dtz.sg");
            capabilities.SetCapability("appActivity", "com.dtz.sg.DTZMobility");




            //Application path and configurations
            capabilities.SetCapability("app", @"D:\Softwares\Android\ADT\ADT\sdk\build-tools\android-4.2.2\sg-stag-1.0.6.apk");

            driver = new AppiumDriver(new Uri("http://127.0.0.1:4723/wd/hub"), capabilities);

            Thread.Sleep(5000);

           // String title = driver.Title;

            driver.FindElement(By.Name("Login")).Click();



        }

But when i debug, i got this error on the code:

{"Object reference not set to an instance of an object."}

Does someone have any idea?
