Question

我正在使用WPF应用程序并使用MVVM。我正在使用异步方法调用WCF服务，它阻止了UI。有时它完全超时。我的网站使用相同的服务（但不使用异步调用）没有问题。这是我的代码和客户端配置。

    private void ProcessLogin()
    {
        if (Username == null || Password == null)
            return;

        _working = true;
        CommandManager.InvalidateRequerySuggested();
        Status = "Authenticating User";

        _authClient.BeginLogin(Username, Password, "", false, EndLogin, null);
    }

    protected void EndLogin(IAsyncResult asyncResult)
    {
        LoggedIn = _authClient.EndLogin(asyncResult);

        if (!LoggedIn)
        {
            Status = "Authentication Failure";
        }
        else
        {
            DialogResult = true;
        }
        _working = false;
        CommandManager.InvalidateRequerySuggested();
    }

<basicHttpBinding>
    <binding name="BasicHttpBinding_AuthenticationService" closeTimeout="00:01:00"
        openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"

        </security>
    </binding>
</basicHttpBinding>

<endpoint address="https://path_to_service:444/Authentication.svc"

            contract="AuthService.AuthenticationService" name="BasicHttpBinding_AuthenticationService" />

看起来你有一个无限循环，你在endlogin中调用endlogin。

来自WPC MVVM应用程序的异步WCF调用定时并挂起UI
