In this post I described the problem that by default, DataAnnotation validation doesn't recursively inspect all properties in an object for DataAnnotation attributes. There are several solutions to this problem, but in this post I used the MiniValidation library from Damian Edwards. This simple library provides a convenience wrapper around DataAnnotation validation, as well as providing features like recursive validation. Finally I showed how you can replace the built-in DataAnnotation validation with a MiniValidation-based validator

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddOptions<MySettings>()
    .BindConfiguration("MySettings")
    .ValidateMiniValidation() // 👈 Replace with mini validation
    .ValidateOnStart();

var app = builder.Build();

OptionsValidationException: 
  DataAnnotation validation failed for 'MySettings' member: 'Nested.Value' with errors: 'The Value field is required.'.; 
  DataAnnotation validation failed for 'MySettings' member: 'Nested.Count' with errors: 'The field Count must be between 1 and 100.'.

HTTP Logging is a middleware that logs information about HTTP requests and HTTP responses. HTTP logging provides logs of

HTTP request information
Common properties
Headers
Body
HTTP response information

HTTP Logging is valuable in several scenarios to

Record information about incoming requests and responses
Filter which parts of the request and response are logged
Filtering which headers to log

The current process creates friction for users. Finding an OTP within an SMS message, then copying and pasting it to the form is cumbersome, lowering conversion rates in critical user journeys. Easing this has been a long standing request for the web from many of the largest global developers. Android has an API that does exactly this. So does iOS and Safari
