Remarks
Normally, an application can retrieve the cached ProvisioningData value from the endpoint using the GetProvisioningData() method. The cache is renewed periodically. The application should use this method when it believes that the cached provisioning data is stale or empty. Unlike other methods on the endpoint this method can be invoked even without establishing the endpoint.
