Examples

The following code shows how to override this method.

internal class MyClientCredentialsSecurityTokenManager :

Remarks

The SecurityTokenProvider class is responsible for obtaining tokens for a given ServiceModelSecurityTokenRequirement. Optionally token providers support renewing and canceling tokens as well.
