At the time of writing this post, default ASP.NET Core SPA templates allow you to create Angular 5 based app with Visual Studio without installing any third-party extensions or templates. Angular 6 is out now and you can also upgrade the Angular 5 app to Angular 6 . What if you want to create Angular 6 app with VS 2017? This post talks about how to create an Angular 6 App with Visual Studio 2017 and how to extend it with a simple example. 

When you create a .NET application in Visual Studio, it contains two build configurations: Debug and Release. But what does this mean exactly? 

In this C# 8 tutorial, I am going to introduce a selection of currently planned features which will most probably end up in the final release. All of the C# 8 features are still early in development and are likely to change. 

In ASP.NET Core MVC and Web API are parts of the same unified framework. That is why an MVC controller and a Web API controller both inherit from Controller base class. Usually a Web API controller has maximum of five actions - Get(), Get(id), Post(), Put(), and Delete(). However, if required you can have additional actions in the Web API controller. This article shows how.

Let's say you have a Web API controller named CustomerController with the following skeleton code. 

The future of C#
Over the last year we shipped no less than three "point releases" of C# (7.1, 7.2 and 7.3), full of small but useful language features. Mads and Dustin will race you through a tour of these, before turning to some of the big things we have in store for the future: Nullable reference types, recursive patterns, asynchronous streams and more. 

.NET Core, the reinvention of the Microsoft .NET Framework as an open source, cross-platform development choice, is a key focus of the upcoming features planned for the Visual Studio IDE.

In conjunction with .NET Standard -- a spec detailing what .NET APIs should be available on all .NET implementations -- .NET Core retains compatibility with .NET Framework, Xamarin and Mono while letting developers use Windows, macOS or Linux machines to code for mobile, cloud and embedded/IoT projects.

While still primarily driven by Microsoft dev teams, .NET Core is hosted on a GitHub repository and is supported by the .NET Foundation, an independent organization created by Microsoft three years ago to improve its open source development and collaboration.

Peeking at the Visual Studio Roadmap (updated last week) reveals .NET Core figures prominently in upcoming functionality for the IDE, both in the near-term and long:  

Sometimes, we want users to log in to our application using their existing credentials from third-party applications, such as Facebook, Twitter, Google, etc. In this article, we are going to look into the authentication of ASP.NET Core app using a Google account. 

Although most of the attention is on .NET Core, development continues on the original .NET Framework. Microsoft has recently released a preview of .NET Framework 4.7.2 with updates to ASP.NET, ADO.NET, WCF, WPF, and even Windows Forms. You can see the complete release notes on GitHub.
