4.3.0

[4.3.0] - 2026-06-21

Added

• ErrorCodeRegistry - to aggregate error codes and call graphs from multiple assemblies and provides traversal to collect all error codes for any entry-point method
• MethodCallGraph always emitted (even if empty) so consumer code can safely reference the field. Does not include calls to System.* and Microsoft.* namespaces (BCL has no error codes)
• ExcludeFromErrorCodeAnalysisAttribute to exclude class/method from error code analysis (respected by both method analysis and call graph)

Full Changelog: 4.2.0...4.3.0

4.2.0

Added

• CollectErrorCodesAttribute.Types property to filter error code declarations by type, reducing false positives

Full Changelog: 4.1.0...4.2.0

4.1.0

No breaking changes here expected.

[4.1.0] - 2026-06-21

• source gen class refactored
• faster BFS algo used instead of loops
• added readme with supported features
• interface method calls also supported if we can find implementations compilation (merged all error codes)
• incremental source gen with cache - method changes do not recalculate all the methods (only changed)

Full Changelog: 4.0.0...4.1.0

[3.1.0] - 2025-04-02

Added

Backport bug fixes and features from 3.1.0 to 2.3.0

[2.4.0] - 2025-04-02

Added

• Allow to filter additional data from domain exception that will be added to ProblemDetails. Specify DomainExceptionSettings.AdditionalDataResponseIncludingFilter.

Fixed

• DetailedMessage from DomainException not passed to ProblemDetails response

Error criticality level support

Changes:

• CriticalityLevel added to [ErrorDescription], also added to metric label, logs, api response. So you can use it to differ codes by its error criticality level.

BREAKING CHANGES:

• Dropped field "IsObsolete" on [ErrorDescription]
• ErrorCodesMeter now accept ErrorDescription and instance of error, instead of DomainException. This helps to use not only exceptions, but also Result pattern.
• error_codes_total metric now have level label from error code
• DomainExceptionSettings.OnExceptionCreated replaced by DomainExceptionSettings.OnErrorCreated callback

Upgrade to .NET 9 and error criticality level support

Changes:

• Update to .NET 9
• CriticalityLevel added to [ErrorDescription], also added to metric label, logs, api response. So you can use it to differ codes by its error criticality level.
• DomainException that generated by source generators now uses FrozenDictionary for internal error codes cache

BREAKING CHANGES:

• Serilog dependency upgraded to 4.1.0
• OpenTelemetry.Api dependency upgraded to 1.10.0
• No more replace Microsoft.AspNetCore.Http.DefaultProblemDetailsWriter by Rfc7231ProblemDetailsWriter. Bug dotnet/aspnetcore#52577 was fixed
• Dropped support of any .NET lower than .NET 9
• Dropped field "IsObsolete" on [ErrorDescription]
• ErrorCodesMeter now accept ErrorDescription and instance of error, instead of DomainException. This helps to use not only exceptions, but also Result pattern.
• error_codes_total metric now has level label from error code
• DomainExceptionSettings.OnExceptionCreated replaced by DomainExceptionSettings.OnErrorCreated callback

Add ProblemDetails support
