NET 6 Release Candidate 2. منتشر شد
We are excited to release .NET 6 Release Candidate 2. It is the second of two “go live” release candidate releases that are supported in production. For the last couple months, the team has been focused exclusively on quality improvements. There are a lot of new features in the release, which only fully come together near the end. The team is currently validating end-to-end workflows to find the places where design intentions and technical reality don’t yet fully match. That’s led to teams tightening leaky pipes and paving paths all the way to their destination.
ASP.NET Core 1.0 is the ground-up rewrite of ASP.NET, MVC and Web API, bringing a new paradigm in building web applications and APIs in .NET. With this rewrite brought new techniques in building SOLID applications, and updated some existing patterns and tools.
In this session, we'll take a lap around some of the major extension points of ASP.NET Core 1.0, walking through how these features can help us build cleaner, more maintainable systems. We'll cover web APIs, traditional MVC applications, controllers, views, filters, dependency injection, tag helpers and more. With a SOLID foundation, our ASP.NET Core applications will be dead simple to build and maintain.

Summary
It’s pretty easy to differentiate use cases for Result and exceptions. Whenever the failure is something you expect and know how to deal with – catch it at the lowest level possible and convert into a Result instance. If you don’t know how to deal with it – let it propagate and interrupt the current business operation. Don’t catch exceptions you don’t know what to do about.
