 Additionally, cases for enums are always emitted as `public`. This is so that they align with C# and the rest of the .NET platform.
 
+To enable [exhaustive matching](match-expressions.md) for only the defined enum cases, you can suppress warning FS0104 using the directive `#nowarn "104"`. This allows the compiler to treat only declared enum values as valid during pattern matching, avoiding the need for a catch-all case — useful when you're certain all values are covered.
