AL0107 - Orphaned [TracedTag] attribute

[TracedTag] on a parameter has no effect without [Traced] on the method or class

Source: Al0107OrphanedTracedTagAnalyzer.cs

Description

[TracedTag] marks a parameter to be recorded as a span tag during instrumentation. Without [Traced] on the method or its declaring class, no span is created and the tag is silently ignored.

Bad Code

public class OrderService
{
    // No [Traced] on method or class — tag is orphaned
    public void Process([TracedTag] string orderId) { }
}

Good Code

[Traced("MyApp")]
public class OrderService
{
    public void Process([TracedTag] string orderId) { }
}
