Implementing Single Sign-On using SAML 1.1, x.509, LDAP in C#.net

Hi,

I got a requirement from the client i.e implementing single sing on using SAML 1.1( LDAP & X.509)in .net. I searched almost entire internet but no use. I have perfect knowledge regarding SAML but i dont know how to implement it in C#.net. Where do i get any papers or document that tells how to implement SSO using SAML in .net . What are the key steps involved in implementing it? What are the topics i need to cover to complete this task. I am literally struck at this point, any help would be apprciated.

Thanks in advance
