OPC UA .NET Standard — Client.ComplexTypes (legacy reflection-emit loader)
OPCFoundation.NetStandard.Opc.Ua.Client.ComplexTypes is the legacy
reflection-emit complex-type and data-type loader. It walks a
server's DataTypeSystem, fetches the missing DataType definitions,
generates runtime types using System.Reflection.Emit, and registers
them with the IServiceMessageContext so the encoders / decoders can
round-trip server-defined Structures, Optionals, Unions, and
Enumerations.
When to use this package
Most consumers do not need this package. The
OPCFoundation.NetStandard.Opc.Ua.Clientpackage ships a NativeAOT-friendly complex-type loader that does not requireSystem.Reflection.Emit— it builds the runtimeStructureDefinition/EnumDefinitiongraphs directly. Prefer that path for any new application, and especially for trimmed / NativeAOT deployments where reflection-emit is unavailable.
Reference Opc.Ua.Client.ComplexTypes only when:
- You have a 1.5.378-era codebase that relied on the
ComplexTypeSystemreflection-emit API and you are not ready to migrate, or - You explicitly need to reflect over the runtime-generated CLR types
(e.g. you bind them into a UI grid, serialize them through a
third-party reflection-based serializer, or use them with
System.Linq.Expressions).
For straight-through encode / decode of server-defined complex types
no consumer-side reflection is required — use Opc.Ua.Client.
Getting started
using Opc.Ua.Client;
using Opc.Ua.Client.ComplexTypes;
var loader = new ComplexTypeSystem(session);
await loader.LoadAsync();
// session.MessageContext.Factory now resolves the server's custom types
// as reflection-emit-generated CLR types.
Target frameworks
net472, net48, netstandard2.1, net8.0, net9.0, net10.0.
The package is not NativeAOT-compatible because the runtime type
emission depends on System.Reflection.Emit.
Additional documentation
See the main repository README
and the Complex Types guide
for the full design (legacy reflection-emit loader vs. the
NativeAOT-friendly loader in Opc.Ua.Client).
