Can I get JSON format data from ACS?

Question

When I began to read the ACS 2.0 document, I realized, ACS integrate with claim based authentication. So if I don't want to use claim in my application, how should I get data in SWT or JSON format?

Does anyone have an example of how to achieve this?

Most simple solution: switch ACS to use SWT token, configure your app to save bootstrap token and use them in your way web.config:

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

Application:

var claimIdentity = Thread.CurrentPrincipal.Identity as ClaimsIdentity;
if (claimIdentity == null)
{
    return;
}

BootstrapContext bootstrapContext = claimIdentity.BootstrapContext as BootstrapContext;
SecurityToken token = null;
//you must configure SWT token handler in web.config or set up 'em manually like
SecurityTokenHandlerCollection handlers = FederatedAuthentication.FederationConfiguration.IdentityConfiguration.SecurityTokenHandlers;
//here is a bug in 4.5 cause a bootstrapContext.SecurityToken disappear sometimes.

if (bootstrapContext.SecurityToken != null)
    {
        token = bootstrapContext.SecurityToken;
    }
else if (!string.IsNullOrEmpty(bootstrapContext.Token))
    {
        token = handlers.ReadToken(new XmlTextReader(new StringReader(bootstrapContext.Token)));
    }
