我正在开发 WPF 应用程序并使用 MVVM。我正在使用异步方法调用 WCF 服务，它阻塞了 UI。有时它只是完全超时。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();
    }

看起来您有一个无限循环，您正在从 endlogin 中调用 endlogin。
