Asynchronously obtains a new certificate or certificate pack from the certificate manager. Returns a task that represents the asynchronous operation. The value of the TResult contains the collection of certificates obtained from the certificate manager.

The ObtainNewCertificateOrCertificatePackAsync methods asynchronously obtain a new application own certificate or certificate pack from the certificate manager, and store it for subsequent usage.

When certificate pack is used, this method operates on certificates with certificate type Ids given by PackCertificateTypeIds.

If the specified certificate type Id is Null, the default certificate type Id from DefaultCertificateTypeId is used instead.

The operation is asynchronous, because it involves multiple steps, and waiting for a finalization of the request by the GDS (see the OpcLabs.EasyOpc.UA.Gds.IEasyUACertificateManagement.FinishRequest method).

For a synchronous alternative, see the ObtainNewCertificateOrCertificatePack(IEasyUAClientServerApplication,UAObtainCertificateArguments) extension method and its overloads.

For an alternative based on asynchronous programming model (APM, System.IAsyncResult) pattern, see the BeginObtainNewCertificateOrCertificatePack method and related extension methods.
