Maintenance Release

Updated Microsoft.IO.RecyclableMemoryStream package to 3.0.0

Maintenance Release

throw pending exception from channel.
mark ServiceResultException Serializable.
fix unit tests.
update readme.

Fix for when remote certificate is null.

v3.2.1

Merge branch 'master' of https://github.com/convertersystems/opc-ua-c…

Refactor channel class names to use Client prefix.

Instead of UaTcpSessionChannel, use ClientSessionChannel. See Readme for details.

        // create a 'ClientSessionChannel', a client-side channel that opens a 'session' with the server.
        var channel = new ClientSessionChannel(
            clientDescription,
            null, // no x509 certificates
            new AnonymousIdentity(), // no user identity
            "opc.tcp://opcua.rocks:4840", // the public endpoint of a server at opcua.rocks.
            SecurityPolicyUris.None); // no encryption

Bug fixes: Check expired certificate. Message chunking.

v3.1.1

Support GetValueOrDefault<> of custom type.

v3.1.0

Support for creating a Type Library of custom Structures

In v3.0, we ask that you mark the assembly containing your custom structures with TypeLibrary() attribute.
The Encoder/Decoder will discover these custom structures and be able to read and write these structures with the server.

using System;
using Workstation.ServiceModel.Ua;

[assembly: TypeLibrary()]
namespace CustomTypeLibrary
{
    [DataTypeId("nsu=http://www.unifiedautomation.com/DemoServer/;i=3002")]
    [BinaryEncodingId("nsu=http://www.unifiedautomation.com/DemoServer/;i=5054")]
    public class CustomVector : Structure
    {
        public double X { get; set; }
        public double Y { get; set; }
        public double Z { get; set; }
        public override void Encode(IEncoder encoder)
        {
            encoder.WriteDouble("X", X);
            encoder.WriteDouble("Y", Y);
            encoder.WriteDouble("Z", Z);
        }
        public override void Decode(IDecoder decoder)
        {
            X = decoder.ReadDouble("X");
            Y = decoder.ReadDouble("Y");
            Z = decoder.ReadDouble("Z");
        }
    }
}

Nullable Reference Types

Adopt nullable reference types (NRT) in preparation for .NET 5.
See https://devblogs.microsoft.com/dotnet/embracing-nullable-reference-types
Thank you, @quinmars

Ignore UTF8 decoder errors. Send nonce, local cert with CreateSession always.

v2.5.1

Merge branch 'master' of https://github.com/convertersystems/opc-ua-c…

Support v1.04 nodes, attributes, status codes.

Support the latest version of the OPC Foundation specification v1.04 with additional types, node attributes, and status codes.
