This pull request modernizes the OPC UA .NET codebase and tests, removes .NET Standard 2.0 support from certificate/security code, and updates test code to use C# 12 and .NET 8+ features for clarity and maintainability.
- Certificate and BouncyCastle interop files (e.g., CertificateBuilder.cs, X509Extensions.cs, X509SignatureFactory.cs) are refactored to drop NETSTANDARD2_0 support and use modern .NET APIs and conditional compilation.
- Test code across the codebase is updated to use default, strongly-typed Parse methods, collection expressions, and improved async/await patterns.
- Exception handling and assertions in tests are modernized, and test method naming is made consistent with Async suffixes.
- The project and build files are updated to clarify Roslynator analyzer usage and remove obsolete netstandard tags.
- General code and test cleanup includes improved null safety, type safety, and removal of deprecated or unused code.
Expose an 'ISession' interface as abstraction to ease unit testing.
Breaking changes are kept to minimal impact, but some changes maybe required to use ISession objects instead of Session.
Note: ISessionClientMethods is hand created, not yet by ModelCompiler
- support for Microsoft.Extensions.Logger.ILogger in Opc.Ua.Core as the new logging interface
- backward compatible with config and TraceEvents
- new API Utils.SetLogger allows to set ILogger
- updated Console samples to demonstrate ILogger support with Serilog
- support for EventSource logging
- see Docs/Logging.md for more info
- Use updated Modelcompiler code generator to produce code which has no dependency on System.Servicemodel
- breaking change, .NET stack which used the NET_STANDARD version have to fix dependencies on System.Servicemodel
- new codegenerator also provides stubs for async client API (NET_STANDARD_ASYNC), currently disabled
- latest V1.04.9 Nodeset
