Hello.

Yes, there has been a change. Please modify your code to use uaDataDialog1.EndpointDescriptor.EndpointSelectionPolicy.CommunicationProfile.MessageSecurityModes
instead,

(the new object is mentioned, but admittedly not best described, here  kb.opclabs.com/What%27s_new_in_OPC_Studio_2025.1 ).

Best regards

I am getting the following build error after upgarding to NuGet version 5.82.423.

Severity    Code    Description    Project    File    Line    Source    Suppression State
Error    BC30456    'AllowedMessageSecurityModes' is not a member of 'UAEndpointSelectionPolicy'.

My code is below:
If server_properties.pSecurityMode = "Sign&Encrypt" Then
      uaDataDialog1.EndpointDescriptor.EndpointSelectionPolicy.AllowedMessageSecurityModes = UAMessageSecurityModes.SecuritySignAndEncrypt ' Sign&Encrypt
End If

Thank you.
