Cause

A type or method has a low maintainability index value.

Rule Description

The maintainability index is calculated by using the following metrics: lines of code, program volume, and cyclomatic complexity. Cyclomatic complexity is a measure of the structural complexity of the type or method.

A low maintainability index indicates that a type or method is probably difficult to maintain and would be a good candidate to redesign.

How to Fix Violations

To fix this violation, redesign the type or method and try splitting it into smaller more focused types or methods.

When to Suppress Warnings

Exclude this warning when a type or method is still considered maintainable despite its large size or when the type or method cannot be split up for some reason.
