using System.Threading.Tasks;

public class SignUpCognitoUserPoolSample
{
    public async Task SignupCognitoUserIntoUserPoolAsync()

        using(var provider = new Amazon.CognitoIdentityProvider.AmazonCognitoIdentityProviderClient(RegionEndpoint.USEast1))
        {
            // 2016/6/22 : As there are still bug with SecretHash, do not create UserPool with Client Secret enabled. http://stackoverflow.com/questions/37438879/resolve-unable-to-verify-secret-hash-for-client-in-amazon-cognito-userpools
            // Sign up new User into your Cognito User Pool
            var signup = await provider.SignUpAsync(new SignUpRequest
            {
                ClientId = "<YOUR USER POOL APPS CLIENT ID>",
                Username = "<YOUR USERNAME TO REGISTER INTO USER POOL>",
                Password = "<YOUR USERPASSWORD TO REGISTER INTO USER POOL>",,
                UserAttributes = new List<Amazon.CognitoIdentityProvider.Model.AttributeType>
                {
                    // INPUT ANY ATTRIBUTES TO REGISTER
                    // Must include Email and Phone, if MFA is enabled
                    new AttributeType
                    {
                        Name = "email",
                        Value = "[email protected]",
                    },
                    new AttributeType
                    {
                        Name = "phone_number",
                        Value = "<PHONE NUMBER WITH COUNTRY CODE. ex: +810311111111>",
                    }
                }
            });
            signup.Dump();
        }
    }
}

Does anyone know how to port this into C# for Unity? I'm not sure if they've released CognitoIdentityProvider for Unity

Hey, I've ported the Cognito Identity Provider from the AWS SDK for .NET 4.5, so that you can use it in Unity, using the .NET Framework 2.0:

After SignUp, how can i UpdateAttributes of Logged-In user? i can not find userPool.getCurrentUser(); in .Net SDK, then how can i get current user and update his attributes in C#.
