Would work on this @Rick-Anderson

Fantastic

@Rick-Anderson for some reason the problemDetailsService.WriteAsync(new { HttpContext = httpContext }); doesn't accept an anonymous type as they said in the docs and it also doesn't resolve a ProblemDetailsContext class due to the fact that it is marked obsolete.
There is also a current issue with the feature dotnet/aspnetcore#43261

@brunolins16 please review. When should we start the documentation?

[brunolins16]

@sammychinedu2ky The issue is related to something different. Can you share your example? I very weird because the ProblemDetailsContext should not be marked as obsolete.

[sammychinedu2ky]

This code below raises the error
if (context.RequestServices.GetService<IProblemDetailsService>() is { } problemDetailsService) { problemDetailsService.WriteAsync((new { HttpContext = context });); }

The error I get is :
Argument 1: cannot convert from '<anonymous type: Microsoft.AspNetCore.Http.HttpContext HttpContext>' to 'Microsoft.AspNetCore.Http.ProblemDetailsContext'
