GlobalExceptionFilter.cs

public class GlobalExceptionFilter : IExceptionFilter, IDisposable
{
  private readonly ILogger _logger;

  public GlobalExceptionFilter(ILoggerFactory logger)
  {
    if (logger == null)
    {
      throw new ArgumentNullException(nameof(logger));
    }

    this._logger = logger.CreateLogger("Global Exception Filter");
  }

  public void OnException(ExceptionContext context)
  {
    var response = new ErrorResponse()
               {
                 Message = context.Exception.Message,
                 StackTrace = context.Exception.StackTrace
               };

    context.Result = new ObjectResult(response)
               {
                 StatusCode = 500,
                 DeclaredType = typeof(ErrorResponse)
               };

    this._logger.LogError("GlobalExceptionFilter", context.Exception);
  }
}

Tried to just copy/paste and use but there're couple issues.

1. Dispose() is not implemented
2. Where does ErrorResponse come from?

Thanks.
