## 0.58.0-alpha.13

### Features

- [#6600](https://github.com/microsoft/typespec/pull/6600) This feature introduces changes to how error models (those using the `@error` decorator) are handled. Error models will now be represented as classes that extend exceptions, and when one of these custom-defined exceptions is thrown, it will produce HTTP errors as a result.
  
  The handling of the returned status code will be resolved in the following ways:
  
  #### If `@statusCode` is defined, the value of the `@statusCode` property will be returned
  In this case, 404 will be returned:
  ```tsp
  @error
  model NotFoundError{
    @statusCode _: 404
  }
  ```
  
  ### If `@statusCode` is not defined, the error `400` will be assigned by default
  In this case, 400 will be returned:
  ```tsp
  @error
  model NotFoundError{
    statusCode: string;
  }
  ```
  
  ### If `@min` and `@max` are defined instead of a specific value, the `@min` value will be returned
  In this case, 500 will be returned:
  
  ```tsp
  model Standard5XXResponse {
    @minValue(500)
    @maxValue(599)
    @statusCode
    statusCode: int32;
  }
  ```
  
  ### If `@statusCode` is defined as a union, the resulting model constructor will require a status code
  In this case, when the model is generated, it will require a status code to be provided:
  ```tsp
  model Standard4XXResponse {
    @statusCode
    statusCode: 400 | 402;
  }
  
  ```
  As a result, the status code must be passed when creating an instance of the model:
  ```csharp 
  throw new Standard4XXResponse(400);
  ```
