Итак, мы столкнулись с ошибкой, которую не можем решить. Мы используем SignalR (Core), чтобы сервер отправлял данные подключенным клиентам. Сервер — это API с .Net Core 3.1, а клиенты — клиенты UWP. В режиме отладки все работает нормально, но когда мы создаем выпуск нашего клиента, соединение SignalR не удалось.

Вот код подключения :

 var connectUrl = await ControllerManager.Instance.GetAsync<string>($"Signalr/connectionurl");
var token = ControllerManager.Instance.EchinoBearerToken;

 _chatHubConnection = new HubConnectionBuilder()
        .WithUrl($"{connectUrl}/signalr/chathub", options => {
            options.AccessTokenProvider = () => Task.FromResult(token);
        })
        .Build();
  

Ошибка :

 Microsoft.AspNetCore.HttpConnections.Client.HttpConnectionOptions on Microsoft.Extensions.Options.OptionsManager [TOptions] violates the constraint of type TOptions
Parameter name : GenericArguments[0[
