LowFile-scopeC# Plug & play

Use enums instead of magic strings

Replace string literals that represent finite sets with enums (optionally flagged) or constants.

Why this matters

Improves type safety and discoverability.

Side-by-side examples engineers can pattern-match during review.

Avoid

if (status == "Approved") { ... }

Prefer

enum Status { Pending, Approved, Rejected }
if (status == Status.Approved) { ... }

Bad

if(role=="Admin")

Good

if(role==Role.Admin)

From the same buckets as this rule.

Critical
Avoid Duplicating String Literals
Store repeated string literals in constants or variables to improve maintainability and reduce redundancy.

Critical
Avoid Empty Methods
Detect methods that have an empty body. If a method is empty, ensure that a comment is present explaining why it remains unimplemented.

Avoid modifying built-in prototypes
Detect modifications to built-in prototypes. Modifying built-in objects can lead to compatibility issues and unexpected behavior. Recommend creating helper functions instead.
