ClaimTypes list

I am parsing FederationMetadata.xml from azure adfs
var entity = new EntityDescriptor(xmldocument.DocumentElement);

I wish to have the list of ClaimTypes, but they are not available in EntityDescriptor object. Should I parse the xml manually or is there any other way?

You will have to parse these yourself as they’re outside the SAML metadata specification.
You’ll see the ClaimTypes fall under a WS-Federation .
Azure AD and ADFS metadata can include a mix of SAML and WS-Federation configuration information.
