Solution
The SaveProfile, SaveIdentity, and SavePrincipal methods on the Security-
CacheProvider class were modified to check the input values and to throw exceptions
if they were null. The following is the modified SaveProfile method.
public override IToken SaveProfile(object profile)
{
if (profile == null)
{
throw new ArgumentNullException("profile");
}
…
}
Verification
Running the test case again after applying the preceding code verified that the cache
threw the ArgumentNullException exception when the input value was null.
