Roles available with Windows Authentication

Question

I'm trying to add Roles authentication to an Action in a Controller in an ASP.NET MVC application. The code looks something like this:

[Authorize(Roles = "SomeRoleName")]
public ActionResult Index()
{
    bool inRole = User.IsInRole("Admin");

If I remove the Authorize attribute and put a breakpoint on the last line in that code sample, is there a way that I can inspect the objects and find out what roles are available?

e.g. I call User.IsInRole("Admin) in the Immediate window and it will give me a true/false value. How can I access the collection of roles available?

Add this to your web.config under system.web:

<roleManager enabled="true" defaultProvider="AspNetWindowsTokenRoleProvider"/>

Then you can use:

string[] arr = Roles.GetRolesForUser(User.Identity.Name);

or:

string[] arr = Roles.GetRolesForUser();
