RefreshingAWSCredentials

The time after which this identity will no longer be valid. If this is null, an expiration time is not known (for example, when using long-term credentials).

The time subtracted from the expiration provided by the credentials provider and then used for determining if the credentials are expired. This provides a buffer to avoid corner case issues of processing time on the client side before the credentials are actually used for signing and validation on the server side.

If credentials are still valid but the expiration is within the Expiration minus PreemptExpiryTime a background refresh of the credentials will be triggered.

Clears currently-stored credentials, forcing the next GetCredentials call to generate new credentials.

GetCredentials may refresh credentials if the credentials are in the pre-empt expiration window. This will trigger a background refresh of the credentials and could force an update to the credentials and to the expiration. Users should not rely on the Amazon.Runtime.RefreshingAWSCredentials.Expiration property before calling Amazon.Runtime.RefreshingAWSCredentials.GetCredentials because the Amazon.Runtime.RefreshingAWSCredentials.Expiration could be updated.

GetCredentialsAsync may refresh credentials if the credentials are in the pre-empt expiration window. This will trigger a background refresh of the credentials and could force an update to the credentials and to the expiration. Users should not rely on the Amazon.Runtime.RefreshingAWSCredentials.Expiration property before calling Amazon.Runtime.RefreshingAWSCredentials.GetCredentialsAsync because the Amazon.Runtime.RefreshingAWSCredentials.Expiration could be updated.
