Why does AmazonCognitoIdentityProviderClient deadlock in C# Xamarin?-CodePudding

I have used the aws-samples example named aws-cognito-dot-net-desktop-app in C# and WPF in a Windows PC application:

No exception or some other type of error occurs.

Is there a way to find out with Visual Studio what is happening?

Any comment or suggestion is welcome.

UPDATE

The way I call SignUpUser is like this:

private async void clickCreateUser(object o, EventArgs e)
{
   ...
   try
   {

      CognitoHelper helper = new CognitoHelper();
      bool success = await helper.SignUpUser(etUserName.Text, etPasswordUser.Text, etEmailUser.Text, etPhoneUser.Text);
      ...

   }
   catch (Exception ex)
   {
    Android.Widget.Toast.MakeText(Application.Context, "Error: "   ex.Message, Android.Widget.ToastLength.Long).Show();
   }
}

UPDATE2

I got an example for Xamarin. Forms of this link:

I need to keep going through the rest of the code to determine other possible issues

CodePudding user response：

The solution is to set the AWS region that is being used, as follows:

Amazon.CognitoIdentityProvider.AmazonCognitoIdentityProviderClient provider = new Amazon.CognitoIdentityProvider.AmazonCognitoIdentityProviderClient(new AnonymousAWSCredentials(), RegionEndpoint.YourRegionAWS);
