Release 2.6.0 generates incompatible .net C# code for data types with optional fields

[larws]

Using the current release of the ModelCompiler the output for nodesets containing datatypes which include optional fields does not match code available in the current SDK release (1.5.375.457). The generated code contains methods in the IEncoder and IDecoder to read and write an encoding mask which are not released by the SDK and will not match with the upcoming release.

The code includes:

• decoder.ReadEncodingMask(typeof(DataType)) see Template ClassWithOptionalFields.cs
• encoder.WriteEncodingMask(nameof(EncodingMask), (uint)EncodingMask) see Template ClassWithOptionalFields.cs

There are currently no methods defined on the interfaces IEncoder and IDecoder with the names ReadEncodingMask oder WriteEncodingMask. In the upcoming release those methods will be added see IEncoder and IDecoder but with different signatures.

Anyone facing the same issue as I am or am I missing something?

The changes are in the master branch and should be part of the next maintenance release.
1.5.376-preview may have the updates.

The changes still differ from the commited template code.

With the new upcoming release of the SDK the IDecoder interface introduces the method ReadEncodingMask(IList<string> masks) which is used in the templates. Since the parameter was introduced because of the decoding of JSON encoded types this part is only needed by the JSON decoder. And in order for the generated types to work with all encodings the template would need to provide all field names in the parameter otherwise it would not work with JSON verbose encoding.

Since the change was introduced in the SDK by @opcfoundation-org it might be useful to reconsider that change.
