c#有对SAML操作的类吗？

[llt_2006]

SAML即安全断言标记语言，英文全称是Security Assertion Markup Language。它是一个基于XML的标准，用于在不同的安全域(security domain)之间交换认证和授权数据。

SAML 如下：
<samlp:Response
xmlns:samlp="urn:oasis:names:tc:SAML:2.0:protocol"
xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion"
ID="identifier_2"
InResponseTo="identifier_1"
Version="2.0"
IssueInstant="2004-12-05T09:22:05Z"
Destination="https://sp.example.com/SAML2/SSO/POST">
<saml:Issuer>https://idp.example.org/SAML2</saml:Issuer>
<samlp:Status>
<samlp:StatusCode
Value="urn:oasis:names:tc:SAML:2.0:status:Success"/>
</samlp:Status>
<saml:Assertion
xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion"
ID="identifier_3"
Version="2.0"
IssueInstant="2004-12-05T09:22:05Z">
<saml:Issuer>https://idp.example.org/SAML2</saml:Issuer>
<!-- a POSTed assertion MUST be signed -->
<ds:Signature

<saml:Subject>
<saml:NameID

是否有类可直接load?
