Error on "app" capability on Visual Studio

Support
1

I’m trying to use Appium on Visual Studio. I stablished the desired capabilities but when I try to run my test I receive an error from Appium on “app” capability.

I don’t know what am I doing wrong using this line:

cap.SetCapability(“app”, “/Users/Oscar_Aguiar/Downloads/app-debug.apk⁩”);.

*I’m using Appium on Visual Studio (both on their latest version)
*I’m using a real Android Device
*I tried to implement the same code from another developers and everything seems to be OK
*I tried using “appActivity” and “appPackage” capabilities with their respective path but none of them works (Appium always gives me an error on that line)
*The .apk file exists
*I’ve been using the same kind of .apk on Xamarin and they worked properly

public class Tests
{
    //Crearting instance for Appium driver
    private AndroidDriver<AndroidElement> driver;


    [SetUp]
    public void InitDriver()
    {

        DesiredCapabilities cap;
        cap = new DesiredCapabilities();
        cap.SetCapability("platformName", "Android");
        cap.SetCapability("platformVersion", "7.0");
        cap.SetCapability("automationName", "UiAutomator2");
        cap.SetCapability("deviceName", "SM-J700M");
        cap.SetCapability("udid", "5203bcfc5346a361");
        cap.SetCapability("app", "/Users/Oscar_Aguiar/Downloads/app-debug.apk⁩");

        driver = new AndroidDriver<AndroidElement>(new Uri ("http://127.0.0.1:4723/wd/hub"), cap);

    }

    [Test]
    public void Test1()
    {
        Assert.IsNull(driver);
        System.Threading.Thread.Sleep(2000);

    }

    [TearDown]
    public void CloseDriver()
    {
        driver.Quit();
    }

}

I expect the app launches on my device running the first steps of my Test

The output is the same error on Appium and Visual Studio on “app” capability
