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

dotnet add package CrCore.Exceptions.AspNet

Register the default exception handling during application startup.

builder.Services.AddCrExceptions();

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
InternalException Error
OtherUnregistered Debug

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,
  "detail": "The requested resource was not found.",
  "instance": "/api/users/1",
  "errors": [
    {
      "code": "Identity.UserNotFound",
      "message": "User was not found."
    }
  ],
  "traceId": "..."
}

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,
  "detail": "An unexpected error occurred.",
  "instance": "/api/users/1",
  "errors": [
    {
      "code": "InternalError",
      "message": "An unexpected internal error occurred."
    }
  ],
  "traceId": "..."
}
