webpack is arguably the most popular bundler right now and this is the first major release in over two years. We get big improvements to caching (and therefore performance), reduced bundle sizes with better tree shaking, and a variety of breaking changes to prepare for the future (automatic Node polyfills are gone, for one). 

Today, the Entity Framework Core team announces the sixth preview release of EF Core 5.0. This release includes split queries for related collections, a new “index” attribute, improved exceptions related to query translations, IP address mapping, exposing transaction id for correlation, and much more. 

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.'.

Data structure is a particular way of organizing data in a computer. The developer must choose the appropriate data structure for better performance. If the developer chooses bad data structure, the system does not perform well. This article explains the each data structure advantages and usage. 

the most visible change of this release is the addition of the new client stack and its 17 web providers that aim at offering an alternative to the aspnet-contrib providers (additional services will be added in future versions of OpenIddict) 

In 4.6.2 we will no longer throw PathTooLongException if we see a path that is >= MAX_PATH. If the OS doesn’t like it we’ll surface PathTooLong, but we won’t second guess what the OS will do. This enables you to use extended long paths and, if the OS would let you, regular long paths.
