OpcUaServer.IntegrationTests was 4F. Two distinct, previously-masked issues:
1. Cert-store gap: the in-test client SecurityConfiguration used a bare
new SecurityConfiguration()/CertificateIdentifier(), so ValidateAsync threw
'TrustedIssuerCertificates StorePath must be specified' before any connect.
Added TestClientSecurity helper building Directory own/issuer/trusted/rejected
stores under a throwaway temp PKI dir (mirrors DefaultApplicationConfigurationFactory);
wired into DualEndpointTests + SubscriptionSurvivalTests.
2. Fixing #1 unmasked an SDK-version drift: the 1.5.378 node-cache read path
throws ServiceResultException(BadNodeIdUnknown) for a removed node instead of
returning a bad DataValue. The two subscription-survival assertions now expect
the throw via Should.ThrowAsync. Behavior under test (removed node -> unknown)
is unchanged; only the delivery mechanism differs.
Suite 4F -> 4/4 green. Integration-sweep follow-up #5.
Opc.Ua.Server was pinned 1.5.374.126 while Client/Configuration were 1.5.378.106, so the
published Host unified Opc.Ua.Core to 1.5.378 (which dropped Opc.Ua.INodeIdFactory that Server
1.5.374 referenced). Every driver-role node (and the fused site nodes) failed to start the OPC
UA server with TypeLoadException, leaving the OPC data plane dead and the site UIs at 503.
Align all OPC UA packages to 1.5.378.106 (bump Server; drop the Opc.Ua.Configuration/Client
VersionOverrides in OpcUaServer + its integration tests) and port the server host to the
1.5.378 async API:
- ApplicationInstance requires an ITelemetryContext ctor (DefaultTelemetry.Create)
- Start/Stop/LoadApplicationConfiguration/Validate -> async; CheckApplicationInstanceCertificate
-> CheckApplicationInstanceCertificatesAsync
- ImpersonateEventHandler is now (ISession, ImpersonateEventArgs)
- UserNameIdentityToken.DecryptedPassword is now byte[] (UTF-8 decode)
- tests ported (byte[] passwords; async discovery/session/read client API)
Verified: full solution builds, OpcUaServer unit tests 52/52, and in docker-dev all six OPC
endpoints (4840-4845) listen and the site UIs return 302 (were 503). End-to-end OPC behaviour
(read/write/subscribe/security under 1.5.378) still needs a functional client test.
