MemberEvidence

Examples

The following example demonstrates how to retrieve a instance from an that has been enriched with embedded insights. It throws an ArgumentNullException enriched via ExceptionInsights.Embed with the current method and runtime arguments, then catches and extracts the descriptor. The MemberEvidence is read from the descriptor's evidence dictionary, and its member signature and runtime parameter count are written to the console, showing how to capture diagnostic context at the point of failure.
