We released .NET Core 2.1.1. This update includes .NET Core SDK 2.1.301, ASP.NET Core 2.1.1 and .NET Core 2.1.1. 

This update is the latest in a cumulative series of feature additions and bug fixes for Visual Studio 2012.

I must say that Rider is pretty impressive. Not only does it offer most features of Visual Studio, even of quite expensive editions, but it even has more.  

Stop writing your changelogs manually

How do you usually keep track of the changes in your projects? Do you use GitHub releases? Do you update your changelogs manually? In this article, I will explain how I handle this topic. This is just one way of doing it, feel free to stick around if you are interested in the topic 🔥

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.'.
Microsoft.Extensions.Options.OptionsFactory<TOptions>.Create(string name)
