ObtainNewCertificateAsync(IEasyUAClientApplication,UAEndpointDescriptor) Method



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.Application.Extensions Namespace > IEasyUAClientApplicationExtension Class > ObtainNewCertificateAsync Method : ObtainNewCertificateAsync(IEasyUAClientApplication,UAEndpointDescriptor) Method
The OPC UA client application object that will perform the operation.
The GDS endpoint acting as OPC UA certificate manager (CM).
Asynchronously obtains a new application instance certificate from the certificate manager, and stores it for subsequent usage.
Syntax
'Declaration
 
<ExtensionAttribute()>
<NotNullAttribute()>
Public Overloads Shared Function ObtainNewCertificateAsync( _
   ByVal application As IEasyUAClientApplication, _
   ByVal gdsEndpointDescriptor As UAEndpointDescriptor _
) As Task(Of X509Certificate2)
'Usage
 
Dim application As IEasyUAClientApplication
Dim gdsEndpointDescriptor As UAEndpointDescriptor
Dim value As Task(Of X509Certificate2)
 
value = IEasyUAClientApplicationExtension.ObtainNewCertificateAsync(application, gdsEndpointDescriptor)

Parameters

application
The OPC UA client application object that will perform the operation.
gdsEndpointDescriptor
The GDS endpoint acting as OPC UA certificate manager (CM).

Return Value

Returns a task that represents the asynchronous operation. The value of the TResult contains the certificate obtained from the certificate manager.
Remarks

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.IEasyUACertificateManagementClient.FinishRequest method).

For a synchronous alternative, see the ObtainNewCertificate(IEasyUAClientApplication,UAEndpointDescriptor) extension method and its overloads.

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

Requirements

Target Platforms: .NET Framework: Windows 7 with SP1, Windows Server 2012; .NET Core: Linux, Microsoft Windows
