Rule description

The analysis rules for code metrics allow you to supply an additional file in your project named CodeMetricsConfig.txt. This file contains entries to configure code-metric thresholds for analysis. The following rules are configurable in this file:

This configuration file expects each entry to be in following format:

ini 
'RuleId'(Optional 'SymbolKind'): 'Threshold'
  • Valid values for RuleId are CA1501, CA1502, CA1505, and CA1506.
  • Valid values for the optional SymbolKind are Assembly, Namespace, Type, Method, Field, Event, and Property.
  • Valid values for Threshold are non-negative integers.
  • Lines starting with '#' are treated as comment lines.

For example, the following is a valid configuration file:

ini 
# Comment text

CA1501: 1

CA1502(Type): 4
CA1502(Method): 2

An invalid entry in this configuration file is flagged with the CA1509 diagnostic.

How to fix violations

To fix a violation of this rule, make sure the invalid entry in CodeMetricsConfig.txt gets the required format.

When to suppress warnings
