使用Federation为WCF服务创建客户端的问题

Question

修改我的服务以使用联合（请参阅下面的web.config）后，我的客户端遇到连接问题。在我读过的所有内容中，似乎我应该能够创建

var client = new MyService()

然后在该凭证上设置用户名和密码，然后WCF处理STS令牌的东西，但我没有一个带0参数的构造函数，我只有一个带有绑定和端点地址的构造函数。我没有看到手动创建绑定的方法，并且只想以默认方式使用它，之前当我刚刚使用带有Https的basicHTTPBinding时，我能够使用默认构造函数创建客户端我不明白为什么这样做不遵循相同的逻辑。

该服务具有web.config：
