Description

Reports C# type declarations whose name is longer than a configurable threshold (maxLength, default 40 characters). The rule applies to classes, structs, records, interfaces, enums and delegates.

Rationale

Very long type names hurt readability and usually indicate that a type is mixing multiple responsibilities. A shorter, well-chosen name is easier to read at a call site and forces clearer modelling of the domain.

public class OrderRepository { }                                                  // OK
public class CustomerOrderHistoryAggregationServiceFactoryBuilder { }             // FLAW — too long
public interface IAggregatedReportingDataExportConfigurationProviderRegistry { }  // FLAW — too long

Remediation

Rename the type to a shorter, more focused name. If you cannot shorten it without losing clarity, the type is probably doing too much: split it into smaller, more cohesive pieces.
