asp.net-core - 相当于ASP.NET Core的Response.TrySkipIisCustomErrors吗？

Question

如何防止IIS使用IIS默认错误页面覆盖自定义错误页面？是否有等效于ASP.NET Core的Response.TrySkipIisCustomErrors？
在ASP Net MVC中，我使用下面的代码在没有自定义页面的情况下发送错误，但是在ASP Net Core中，它无法正常工作。

try
{
    // some code
}
catch (Exception ex)
{
    Response.TrySkipIisCustomErrors = true;
    Response.StatusCode = (int)HttpStatusCode.InternalServerError;
    mensagem = ex.Message;
}

您可以尝试编写一个exception处理中间件。这是一个blog post，我已将其用作引用。遵循以下原则

    public class ErrorHandlingMiddleware
    {
      private readonly RequestDelegate next;

      public ErrorHandlingMiddleware(RequestDelegate next)
      {
        this.next = next;
      }

      public async Task Invoke(HttpContext context)
      {
        try
        {
            await next(context);
        }
        catch (Exception ex)
        {
            await CustomHandleExceptionAsync(context, ex);
        }
      }

    private static Task CustomHandleExceptionAsync(HttpContext context, Exception exception)
    {

        if (exception is NotFoundException)
        {

         var customJson = JsonConvert.SerializeObject(new{ error = 
         exception.Message });
         context.Response.ContentType = "application/json";
         context.Response.StatusCode = (int)HttpStatusCode.NotFound;
         return context.Response.WriteAsync(customJson);
       }
   }
