使用 ws-security 创建 WCF 客户端请求，并在 C 中包含 Saml2Assertion#

问：

我必须使用客户端证书调用 wcf 服务，并在 Security 标头中包含我预先构建的自定义 Saml2Assertion。SOAP 请求应如下所示：

<soap:Envelope>
  <soap:Header>
    <wsa:Action>
      ... ACTION ...
    </wsa:Action>
    <wsa:MessageID>47dca6bd-e36d-474a-9e92-3febdd0f123f</wsa:MessageID>
    <wsa:To>....</wsa:To>
