Seem to be getting inconsistent behaviour
If this code is called from a windows app (form) running with elevated privileges (admin account)
eg c# code
OpcLabs.EasyOpc.UA.EasyUAClient UAClient = new OpcLabs.EasyOpc.UA.EasyUAClient();
try
{
string s2 = "";
foreach (OpcLabs.EasyOpc.UA.UAApplicationElement s in UAClient.DiscoverServers("scadaserver"))
{
s2 += "\n" + s.DiscoveryUriString;
}
MessageBox.Show(s2);
}
catch (Exception exc)
{
MessageBox.Show(exc.ToString());
}
Run this once and it seems to work... run it a second time and it throws exception CertificateGenerator not installed (even if it is in the local directory with the running exe)
So try to call the EasyUAClient.Install() on start up of application get exception
System.InvalidOperationException was unhandled
HResult=-2146233079
Message=Precondition failed: SdkCertificateValidationEventHandler == null
Source=OpcLabs.EasyOpcUAInternal

In order to deploy my client app/service: regarding certificates etc. please could you offer some guidance as to what I need to do
Thank You
