Response.TrySkipIisCustomErrors equivalent for asp.net core?

Question

How to prevent IIS from overriding custom error pages with IIS default error pages? Is there a Response.TrySkipIisCustomErrors equivalent for asp.net core? In ASP Net MVC I use the code below to send error without a custom page but in asp net core it is not working.

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

It sounds like you're trying to disable the status code error pages for a particular request. The ASP.NET Core documentation for Handling Errors gives you the answer.

It's not as succinct as the old TrySkipIisCustomErrors flag, but may be clearer what's actually going on:

var statusCodePagesFeature =
    HttpContext.Features.Get<IStatusCodePagesFeature>();

if (statusCodePagesFeature is not null)
{
    statusCodePagesFeature.Enabled = false;
}
