Intro

ASP.NET Core integration for CrCore.Exceptions.

This package provides automatic handling of CrException instances, converts them into RFC 7807 ProblemDetails responses, and supports configurable exception-to-HTTP status code and log level mappings.

Features

ASP.NET Core exception handler
RFC 7807 ProblemDetails responses
Configurable exception → HTTP status code mapping
Configurable exception → log level mapping
Generic handling of unexpected exceptions

Installation

builder.Services.AddCrExceptionsCore();

app.UseExceptionHandler();

Default HTTP Status Code Mapping

Exception	HTTP Status
`ValidationException`	400
`UnauthorizedException`	401
`ForbiddenException`	403
`NotFoundException`	404
`ConflictException`	409
`UnprocessableException`	422
`InternalException`	500

Custom HTTP Status Code Mapping

builder.Services.AddCrStatusCodeMapping(builder =>
{
    builder.AddDefaultMappings();

    builder.Map<MyCustomException>(StatusCodes.Status499ClientClosedRequest);
});

Default Log Level Mapping

Exception	Log Level
`ValidationException`	Debug
`UnauthorizedException`	Debug
`ForbiddenException`	Debug
`NotFoundException`	Debug
`ConflictException`	Debug
`UnprocessableException`	Debug
`InternalException`	Error

Custom Log Level Mapping

builder.Services.AddCrLogLevelMapping(builder =>
{
    builder.AddDefaultMappings();

    builder.Map<MyCustomException>(LogLevel.Warning);
});

ProblemDetails Response

CrException instances are automatically converted into RFC 7807 ProblemDetails.

Example:

{
  "type": "https://tools.ietf.org/html/rfc9110#section-15.5.5",
  "title": "Not Found",
  "status": 404,
  "errors": [
    {
      "code": "TestNotFoundCode",
      "message": "Test not found message"
    }
  ],
  "traceId": "c771b28502648371f14885924e6d1767"
}

Clients should use errors[].code as the stable application error identifier.

Unexpected Exceptions

Exceptions that do not inherit from CrException are converted into a generic internal server error response.

Example:

{
  "type": "https://tools.ietf.org/html/rfc9110#section-15.6.1",
  "title": "An error occurred while processing your request.",
  "status": 500,
  "errors": [
    {
      "code": "InternalError",
      "message": "An unexpected internal error occurred."
    }
  ],
  "traceId": "9bf8d72774b6f2d97cac7607bb19f408"
}
