IProblemDetailsWriter from problem details response

In https://github.com/dotnet/AspNetCore.Docs.Samples/tree/main/fundamentals/middleware/problem-details-service or write a new sample in https://github.com/dotnet/AspNetCore.Docs.Samples/tree/main/fundamentals/middleware

@brunolins16 should we have a IProblemDetailsWriter sample or should we just say, you can create your own IProblemDetailsWriter implementation for advanced customizations. See the ProblemDetailsService for an example.

See IProblemDetailsWriter from problem details response which has a few problems.

@brunolins16 I'm closing this unless you think we need a IProblemDetailsWriter sample or should we just say, you can create your own IProblemDetailsWriter implementation for advanced customizations. See the ProblemDetailsService for an example.

cc @Elfocrash in case you're interested in writing a sample

@Rick-Anderson sorry I missed the first comment, few days ago, we already added a good doc for the ProblemDetails service and maybe just mention is good enough, is important to also mention "Register any IProblemDetailsWriter implementations before the call to the AddProblemDetails".

What that means?

The code doesn't work.

OH! My bad, I just checked and it really doesn't work. I tried to simplify but I missed / changed too much 😢

This is how the blog post code should be ☹️:

public class SampleProblemDetailsWriter : IProblemDetailsWriter
{
    public bool CanWrite(ProblemDetailsContext context)
        => context.HttpContext.Response.StatusCode == 400;

    public ValueTask WriteAsync(ProblemDetailsContext context)
    {
        //Additional customizations

        // Write to the response
        return new ValueTask(context.HttpContext.Response.WriteAsJsonAsync(context.ProblemDetails));
    }
}
