 | MEN016 | Avoid Top-Level Statements | C# [top-level statements](https://learn.microsoft.com/en-us/dotnet/csharp/fundamentals/program-structure/top-level-statements) are only for toy/example programs and should be avoided in long-term code for [consistency and maintainability](https://github.com/dotnet/docs/issues/27420#issuecomment-988776134). |
 | MEN017 | Remove Unused Private Setter | A private set accessor is not needed when an auto property is only assigned in the constructor. Inspired by [C# Essentials' Use Getter-Only Auto-Property](https://github.com/DustinCampbell/CSharpEssentials?tab=readme-ov-file#use-getter-only-auto-property). |
 | MEN018 | Use Digit Separators | Numeric literals should use digit separators ('_' from C# 7) to improve readability. This applies to hexadecimal, binary, and [integer](https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/builtin-types/integral-numeric-types#integer-literals) or [real](https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/builtin-types/floating-point-numeric-types#real-literals) literals. |
-| MEN019 | Async method needs CancellationToken | An async method should take a [CancellationToken](https://learn.microsoft.com/en-us/dotnet/api/system.threading.cancellationtoken) parameter or take a parameter that has a public CancellationToken property. Inspired by [this dotnet issue](https://github.com/dotnet/runtime/issues/78397). |
