CognitoUser does not contain a constructor that contain 4 arguments error and no definition for StartWithSrpAuthAsync at ASP.NET C#

I have been trying to use Cognito Sign In for my application at ASP.NET C# and I have managed to make the user sign up. However, when I am trying to implement the codes for Sign In there are 2 errors at these lines below :
CognitoUser user = new CognitoUser(username,ClientID,userPool,provider);
this line result in "CognitoUser does not contain a constructor that contain 4 arguments error"
and the 2nd error at this part :
authResponse = await user.StartWithSrpAuthAsync(authRequest).ConfigureAwait(false);
this line result in "CognitoUser does not contain definition for StartWithSrpAuthAsync and No Extension Method…accepting a first argument of type ” could be found" error
This is my full code :
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Amazon;
using Amazon.Runtime;
using Amazon.CognitoIdentity;
using Amazon.CognitoIdentityProvider;
using Amazon.CognitoIdentityProvider.Model;
using System.Threading.Tasks;
using System.Configuration;
using Amazon.Extensions.CognitoAuthentication;
namespace WebApplication2
{
public partial class WebForm5 : System.Web.UI.Page
{
const string PoolID = "poolid";
const string ClientID = "clientid";
static Amazon.RegionEndpoint Region = Amazon.RegionEndpoint.USEast1;
protected void Page_Load(object sender, EventArgs e)
{
string username = "user1";
string password = "pass";
string email = "email1";
SignInUser(username,password);
}
static async Task SignInUser(string username, string password)
{
AmazonCognitoIdentityProviderClient provider = new AmazonCognitoIdentityProviderClient(new Amazon.Runtime.AnonymousAWSCredentials(), Region);
CognitoUserPool userPool = new CognitoUserPool(PoolID, ClientID, provider);
CognitoUser user = new CognitoUser(username,ClientID,userPool,provider);
InitiateSrpAuthRequest authRequest = new InitiateSrpAuthRequest()
{
Password = password
};
AuthFlowResponse authResponse = null;
try
{
authResponse = await user.StartWithSrpAuthAsync(authRequest).ConfigureAwait(false);
}
catch(Exception ex)
{
Console.WriteLine("Logon Failed: {0}\n", ex.Message);
return;
}
GetUserRequest getUserRequest = new GetUserRequest();
getUserRequest.AccessToken = authResponse.AuthenticationResult.AccessToken;
}
}
Any help will be appreciated.

Initiate a call with Microsoft Graphs SDK to Teams User

I'm attempting to initiate a call with the Microsoft Graph SDK Create call API using the code sample below. The attempt fails with a Not Found exception.
I have registered the bot application, added the API call permissions and I am able to receive incoming calls from Teams.
It's not clear from the Microsoft documentation whether Teams users can be called directly or whether they have to be allocated a VoIP number. Has anyone been able to use the Graph SDK to call a Teams User? Is there some special configuration a User needs to have in order to be able to receive a call?

Luis + CustomVision in a single Microsoft Bot Framework

i am new to C# and I would like to make a bot mixing Luis services and customvision.
I would like the user to be able to send an image or text to the bot.
I am starting from the microsoft bot framework "core bot"* and the imageprocessing bot** (*https://github.com/microsoft/BotBuilder-Samples/tree/master/samples/csharp_dotnetcore/13.core-bot, **https://github.com/mandardhikari/ImageProcessingBot )
for the moment, i do have this code which is mix between the two samples

I am new to c#, so any insights on the above would be greatly appreciated!

This is essentially repeating what #stuartd says above in the comments.
The method MessageFactory.Attachemnt returns an IMessageActivity so probably best to use a second variable rather than your Activity reply to avoid casting
case FlightBooking.Intent.Weather:
// We haven't implemented the GetWeatherDialog so we just display a TODO message.
var getWeatherMessageText = "TODO: get weather flow here";
var getWeatherMessage = MessageFactory.Text(getWeatherMessageText, getWeatherMessageText, InputHints.IgnoringInput);
await turnContext.SendActivityAsync(getWeatherMessage, cancellationToken);
var attachments = new List<Attachment>();
meesageReply = MessageFactory.Attachment(attachments); //new variable
messageReply.Attachments.Add(Cards.CreateAdaptiveCardAttachment());
break;

Exception in release but not debug

I have wrapped the C# FCM AdminSDK in a WCF. When I publish the code to my local using debug everything works as expected. When I publish the code using release I get a "Object reference not set to an instance of an object." when attempting to instantiate the "Message" object. Why does this happen?
The exception happens on the line "var fcmMessage = new Message()"

How to convert Address from user input into LatLng Xamarin.Android

I am trying to convert a users input in Edit text to LatLng when the Search button is clicked. This will then update the camera and move tot hat position.
Here is my code in the main:
using Android.App;
using Android.Widget;
using Android.OS;
using Android.Gms.Maps;
using Android.Views;
using Android.Gms.Maps.Model;
using System.Collections.Generic;
using Android.Locations;
using System.Linq;
namespace SafeandSound
{
[Activity(Label = "SafeandSound", MainLauncher = true, Icon = "#drawable/icon")]
public class MainActivity : Activity
{
private GoogleMap mMap;
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
// Set our view from the "main" layout resource
SetContentView(Resource.Layout.Main);
SetUpMap();
}
private void SetUpMap()
{
if (mMap == null)
{
FragmentManager.FindFragmentById<MapFragment>(Resource.Id.map);
}
}
public void OnMapReady(GoogleMap googleMap)
{
mMap = googleMap;
}
// Button to Search for Address//
public void onMapSearch(View view)
{
EditText address = (EditText)FindViewById(Resource.Id.searchText);
var addressnew = address.Text;
if (addressnew != null)
{
addressnew = address.Text;
}
Geocoder geoCoder = new Geocoder(this);
IList<Address> coordinates = geoCoder.GetFromLocationName(addressnew, 0);
Address gotAddress = coordinates.FirstOrDefault();
LatLng latLng = new LatLng(gotAddress.Latitude, gotAddress.Longitude);
CameraPosition.Builder builder = CameraPosition.InvokeBuilder();
builder.Target(latLng);
builder.Zoom(10);
CameraPosition cameraPosition = builder.Build();
CameraUpdate cameraUpdate = CameraUpdateFactory.NewCameraPosition(cameraPosition);
}
}
}
When I use this right now, I get an exception error. Please HELP!!!

First you need to check if the Geocoder service is available on the device/emulator via the static method:
Geocoder.isPresent
Note: The use of Geocoder requires Internet access and Google Play services to be installed...
Next you are requesting zero results in the "maxResults" parameter:
GetFromLocationName(addressnew, 0);
int: max number of results to return. Smaller numbers (1 to 5) are recommended
Also you might need to retry the request to obtain results. You should not hammer the service as you will get throttled. Use a retry delay that increasing after each attempt.
Example:
if (!Geocoder.IsPresent)
{
Log.Error("SO", "Geocoder is not present");
}
else
{
var geocoder = new Geocoder(this);
var retry = 0;
do
{
var addressList = await geocoder.GetFromLocationNameAsync("Starbucks 523 Pine Street, Seattle, WA, 98101", 5);
if (addressList.Count > 0)
{
foreach (var address in addressList)
{
Log.Debug("SO", $"{address.Latitude}:{address.Longitude} - {address.FeatureName} : {address.GetAddressLine(0)} : {address.GetAddressLine(1)}");
}
break;
}
retry++;
Log.Warn("SO", $"No addresses returned...., retrying in {retry * 2} secs");
await Task.Delay(retry * 1000);
} while (retry < 5);
}
Output:
[SO] 47.611423:-122.337519 - Starbucks : Starbucks : 400 Pine Street
[SO] 47.611848:-122.335693 - Starbucks : Starbucks : 515 Pine Street
