Description

The MetadataFeatureExtensions class in SysML2.NET/Extend/MetadataFeatureExtensions.cs contains 1 extension method(s) that compute derived properties for the IMetadataFeature interface. These methods currently throw NotSupportedException and need to be implemented.

Checklist

• IMetaclass ComputeMetaclass(this IMetadataFeature)
• List<IElement> ComputeEvaluateFeatureOperation(this IMetadataFeature, IFeature baseFeature)
• bool ComputeIsSemanticOperation(this IMetadataFeature)
• bool ComputeIsSyntacticOperation(this IMetadataFeature)
• IElement ComputeSyntaxElementOperation(this IMetadataFeature) — deferred: requires a MOF reflective metaclass registry (runtime MetadataFeature → reflected IElement) not present in this SDK. Follow-up issue required.

System Configuration

• SysML2.NET version: 0.19.0
• Source file: SysML2.NET/Extend/MetadataFeatureExtensions.cs
