                      QUESTION

                      SignalR never start on iOS using Xamarin Forms

                      Asked 2022-Mar-24 at 14:13

                      I'm trying to use SignalR in my Xamarin Forms project. It works perfectly when I'm using Android (device or simulator). But using the same code on iOS, it hangs at await hubConnection.StartAsync();

                      I'm using Visual Studio 2022. XAML hot reload is disabled. I've tried adding the System.Memory and System.Buffers IncludeAssets None fix.

                      Here's the code

                      public async Task StartObserving()
                      {
                          Uri signalRUri = new Uri("a-valid-uri-string-here");
                          string jwt = await SecureStorage.GetAsync(SecureStorageKeys.IdToken);
                      
                          HubConnection hubConnection = new HubConnectionBuilder()
                              .WithUrl(
                                  signalRUri,
                                  options =>
                                  {
                                      options.AccessTokenProvider = () => Task.FromResult(jwt);
                                      options.WebSocketConfiguration = (clientWebSocketOptions) =>
                                      {
                                          clientWebSocketOptions.RemoteCertificateValidationCallback = (object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) =>

                                      {
                                          if (httpMessageHandler is HttpClientHandler clientHandler)
                                          {

                      Well I had only half of the solution implemented.

                      What fixed it for me was adding this to BOTH the common AND iOS projects. Not only the common project.

                      <PackageReference Include="System.Buffers">
                        <Version>4.5.1</Version>
                        <IncludeAssets>none</IncludeAssets>      
                      </PackageReference>
                      <PackageReference Include="System.Memory">
                        <Version>4.5.4</Version>
                        <IncludeAssets>none</IncludeAssets>      
                      </PackageReference>
