Xamarin not starting remotely on mac agent from windows: "iOS tests are not supported on Windows"

Question

I'm writing mobile autotests in Visual Studio 2015, C#, Xamarin 6.1.3., iOS 10.2, iPhone 6s Plus, Xcode 8.2. And trying to launch autotests remotely from windows 10 on Mac Agent (OS X El Capitan 10.11.6). I've setup remote connection in VS, so xamarin Mac Agent is connected: This is how i'm trying to launch application in my code:

IApp iApp = ConfigureApp
                .iOS
                .DeviceIp(mac_ip)
                .DeviceIdentifier(iphone_device_identifier)
                .AppBundle(/path_to_ipa/application.ipa)
                .Debug()
                .StartApp();

Test fails on the StartApp() method with message "iOS tests are not supported on Windows.":

System.Exception: iOS tests are not supported on Windows.

Earlier i've launched the same application using appium on the same device and mac - everything was OK.

I haven't specified .DevicePort() because i don't know how to get the port, but i guess it's not neccessary when only 1 device is connected.

Also I've tried to launch in simulator, but i've got the same error.
