how can i access the raw xml of the saml token?

I can get all the claims values with code like this:

ClaimsPrincipal cp = Thread.CurrentPrincipal as ClaimsPrincipal;            
ClaimsIdentity cid = (ClaimsIdentity)cp.Identity;

foreach (Claim claim in cid.Claims)
{
   ...
}

but i want to be able to read the entire token as i suspect a some info i need is in a non-attribute section of the token. I've read about the security token visualizer control, but it's not something i can use because i don't want end users seeing the control output, but would like to send the raw token xml via email.

Solution

First you must configure WIF to save the "BootstrapContext":

<system.identityModel>
  <identityConfiguration saveBootstrapContext="true">

Then you can use the Property "BootstrapContext" on the "ClaimsIdentity"

ClaimsPrincipal cp = Thread.CurrentPrincipal as ClaimsPrincipal;
ClaimsIdentity cid = (ClaimsIdentity)cp.Identity; 
BootstrapContext bc = cid.BootstrapContext as BootstrapContext;

And use the "Token" Property on the BootstrapContext to get the raw xml of the saml token.
