Xamarin PCL self signed certificat for Android and IOS - xamarin

Question

I'm trying to pass my full Rest service from http to https.
I created a self-signed certificate, I had it to IIS Express. I validate it on google Chrome and it work perfectly fine with postman. My rest service work in http and https.
I use a PCL project (IOS and Android) everything is working fine with http request but I have exception with https request. the exception message is null.
I tried to create a test certificate directly from Visual Studio 2015 but the button is disabled in properties ->Signing.
I also tried to install my self-signed certificate as a Trusted Root but no success for the communication between my simulator and my rest Service.
my code
public partial class MainPage : ContentPage
{
private string url = string.Empty;
private HttpClient _client;
public MainPage()
{
InitializeComponent();
switch (Device.RuntimePlatform)
{
case Device.iOS:
_client = new HttpClient(new NSUrlSessionHandler());
break;
case Device.Android:
_client = new HttpClient();
break;
}
_client = new HttpClient();
test();
}
private async void test()
{
//url = "http://192.168.1.106:9630/PrototypeB.svc/Test";
url = "https://192.168.1.106:44301/PrototypeB.svc/Test";
try
{
var _content = await _client.GetStringAsync(url);
List<Test> _posts = JsonConvert.DeserializeObject<List<Test>>(_content);
}
catch (HttpRequestException e)
{
string test = e.Message;
}
catch (Exception e)
{
string test = e.Message;
}
}
}
How can I communicate with my Android and IOS Simulator with https and self-signed certificate?

You can use ServicePointManager to ignore the certificate validation check.
Execute the code in your iOS and Android platforms like this:
System.Net.ServicePointManager.ServerCertificateValidationCallback += (se, cert, chain, sslerror) => {
return true;
};

Also, ModernHttpClient Pro provide this feature, but it is not free.
