System.MissingMethodException "Microsoft.Kiota.Http.HttpClientLibrary.KiotaClientFactory" .NET 4.8

[bfany365]

Hi

I have already read similar questions but they did not help me:

https://github.com/microsoftgraph/msgraph-sdk-dotnet/issues/2520 https://github.com/microsoftgraph/msgraph-sdk-dotnet/issues/2533 https://github.com/dotnet/runtime/issues/28826

The error:

Method not found: 'System.Net.Http.HttpClient Microsoft.Kiota.Http.HttpClientLibrary.KiotaClientFactory.Create(System.Net.Http.HttpMessageHandler)'.

Stack Trace:

I use resharper to dig into to the referenced library and I can see the KiotaClientFactory exists:

 public static class KiotaClientFactory
    {
        /// <summary>
        /// Initializes the <see cref="HttpClient"/> with the default configuration and middlewares including a authentication middleware using the <see cref="IAuthenticationProvider"/> if provided.
        /// </summary>
        /// <param name="finalHandler">The final <see cref="HttpMessageHandler"/> in the http pipeline. Can be configured for proxies, auto-decompression and auto-redirects </param>
        /// <returns>The <see cref="HttpClient"/> with the default middlewares.</returns>
        public static HttpClient Create(HttpMessageHandler? finalHandler = null)
        {
            var defaultHandlers = CreateDefaultHandlers();
            var handler = ChainHandlersCollectionAndGetFirstLink(finalHandler ?? GetDefaultHttpMessageHandler(), defaultHandlers.ToArray());
            return handler != null ? new HttpClient(handler) : new HttpClient();
        }

public static ICallCollection Calls(this ICommunicationsClient client, bool maintainState = true)
    {
      IInternalCommunicationsClient internalClient = (IInternalCommunicationsClient) client;
      return (ICallCollection) internalClient.GetOrAddResourceCollection<StatefulCallCollection>(maintainState, (Func<StatefulCallCollection>) (() =>
      {
        BaseBearerTokenAuthenticationProvider authenticationProvider = new BaseBearerTokenAuthenticationProvider((IAccessTokenProvider) new AccessTokenProvider());
        HttpClient httpClient = KiotaClientFactory.Create((HttpMessageHandler) null);
        httpClient.BaseAddress = new Uri(internalClient.BaseUrl);
        CallsRequestBuilder calls = new GraphServiceClient(httpClient, (IAuthenticationProvider) authenticationProvider, (string) null).Communications.Calls;
        internalClient.NotificationDispatcher.RegisterDispatcherGetOrAdd(calls.ToGetRequestInformation((Action<RequestConfiguration<CallsRequestBuilder.CallsRequestBuilderGetQueryParameters>>) null)?.URI.ToString().SanitizeResource(client.BaseUrl), (Func<INotificationDispatcher>) (() => (INotificationDispatcher) new NotificationDispatcher(internalClient.GraphLogger, 3, doesNotificationRequireSyncResponse: new Func<NotificationEventArgs, bool>(CommunicationsClientExtensions.ShouldProcessNotificationInSync))));
        return new StatefulCallCollection(internalClient, internalClient.GraphClient, calls, maintainState);
      }));
    }

The error happens when using trying to add event handler for incoming call:

                var builder = new CommunicationsClientBuilder(_config.AppName, BotConfig.MicrosoftAppId, GraphLogger);
                builder.SetAuthenticationProvider(AuthenticationProvider);
                builder.SetNotificationUrl(SignalingUrl);
                builder.SetServiceBaseUrl(new Uri(BotConfig.TeamsPlaceCallEndpointUrl));

                TeamsClient = builder.Build();

                TeamsClient.Calls().OnIncoming += BotEndpoint_OnIncoming;

Thanks for raising this @bfany365

I suspect the issue here is that that the Microsoft.Graph.Communications.Calls package is referencing an old/incorrect version of the kiota http package here.

Do you get a different result if you drop the Microsoft.Graph.Core and the Microsoft.Graph dependency and let the compiler resolve the version the Microsoft.Graph.Communications.Calls dependency?

Hi @andrueastman

I dropped the "Microsoft.Graph.Core" and "Microsoft.Graph" and did not work.

I made a new .net 4.8 project from scratch and just added the required dependencies one by one and here is the list that worked for the new project:

Azure.Core | 1.36.0.0 Microsoft.Bcl.AsyncInterfaces | 7.0.0.0 Microsoft.CSharp | N/A Microsoft.Extensions.Logging.Abstractions | 2.2.0.0 Microsoft.Graph | 5.38.0.0 Microsoft.Graph.Communications.Calls | 1.2.0.10574 Microsoft.Graph.Communications.Client | 1.2.0.10574 Microsoft.Graph.Communications.Common | 1.2.0.10574 Microsoft.Graph.Communications.Core | 1.2.0.10574 Microsoft.Graph.Core | 3.1.3.0

However, I need to figure out how to make it work in the old project and will let you know after trying.

[bfany365]

These are the packages that worked:

Microsoft.Graph, 5.38.0 Microsoft.Graph.Communications.Client, 1.2.0.10563 Microsoft.Graph.Communications.Common, 1.2.0.10563 Microsoft.Graph.Communications.Core, 1.2.0.10563 Microsoft.Graph.Core, 3.1.3 System.Net.Http.WinHttpHandler, 6.0.0

Thanks for confirming this @bfany365

At the end of the day, I believe, the Microsoft.Graph.Communications.Core libraries will need to release a new version that targets later version of the library here https://www.nuget.org/packages/Microsoft.Kiota.Http.HttpClientLibrary.

As this library is not maintained by us, would you be willing to create an issue for this at this repo? https://github.com/microsoftgraph/microsoft-graph-comms-samples
