Severity: error

This diagnostic is issued when @markAsLro is applied to an operation that already has real LRO metadata.

Impact

• Area: LRO SDK metadata. Blocks or rejects a redundant legacy LRO marker when the operation already has real long-running-operation metadata.
• Not affected: Existing LRO polling metadata remains the source of generated behavior.

Diagnostic Message

TCGC reports:

@markAsLro decorator is ineffective since this operation already returns real LRO metadata. Please remove the @markAsLro decorator.

✅ How to Fix

Remove @markAsLro from operations that are already modeled as long-running operations.
