.NET Core 2.0 Changes – 4 Key Things to Know

1. .NET Standard 2.0 Expanded APIs & the Ability to Reference Full Framework Libraries

.NET Standard broadens the set of APIs available to include a lot of the missing features. It now supports 32,000+ APIs. It is now much easier to port your code to a .NET Standard library without major code changes.
One of the biggest problems with .NET Core was the lack of third-party libraries. For example, when 1.0 came out, popular logging libraries like log4net were not even available (it is now). However, this was really only a problem if you wanted to deploy your app on Mac or Linux. You could have used .NET Core and targeted full .NET framework and not had these issues.
.NET Standard 2.0 has added a new compatibility shim that will enable any .NET Core app to reference any full framework library.

2. Expanded OS Support

One of the big goals with .NET Core is portability across multiple operating systems. Including desktops, servers, and even mobile. Microsoft and the community continue to expand the support of .NET Core.
Linux is now treated as a single operation system instead of different distribution. This also holds true for Windows and macOS. For example, there are no individual runtimes any longer for win8 and win10.
A preview is also now available for ARM32 support.

3. ASP.NET Core Razor Pages Are New

ASP.NET now supports razor syntax based pages, called Razor Pages. You can now essentially create a razor view without a controller. Although, you can make a class that inherits from PageModel which is basically a controller and model class dedicated to that page. I could see this being useful in some cases and could help with breaking down big complex controllers.

4. Visual Basic for .NET Core Is Here!

OK, I’m sure you are really excited about this! Visual Beginners All-purpose Symbolic Instruction Code now supports .NET Core! Currently, it is limited to making class libraries and console application. They say more is coming soon.

ASP.NET Core - Create New Project

You can start building a new ASP.NET Core Application from the  File → New Project  menu option. On the New Project dialog box, you will see the following three different templates for Web projects − ASP.NET Web Application  − The simple ASP.NET application templates . ASP.NET Core Web Application (.NET Core)  − This will start you with a crossplatform compatible project that runs on the .NET Core framework. ASP.NET Core Web Application (.NET Framework)  − This starts a new project that runs on the standard .NET Framework on Windows. In the left pane, select  Templates → Visual C# → Web  and in the middle pane select the ASP.NET Core Web Application (.NET Core) template. Let us call this application  FirstAppDemo  and also specify the Location for your ASP.NET Core project and then Click OK. In the above dialog box, you can select a specific template for the ASP.NET application from the available ASP.NET Core Templates. ...

ASP.NET Core - Attribute Routes

Learn another approach to routing and that is attribute-based routing. With attribute-based routing, we can use C# attributes on our controller classes and on the methods internally in these classes. These attributes have metadata that tell ASP.NET Core when to call a specific controller. It is an alternative to convention-based routing. Routes are evaluated in the order that they appear, the order that you register them in, but it's quite common to map multiple routes particularly if you want to have different parameters in the URL or if you want to have different literals in the URL. Example Let us take a simple example. Open the  FirstAppDemo  project and run the application in the browser. When you specify  /about , it will produce the following output − What we want here is that when we specify  /about , the application should invoke the Phone action of the AboutController. Here, we can enforce some explicit routes for this controller using a Ro...

Features of Node.js

Following are some of the important features that make Node.js the first choice of software architects. Asynchronous and Event Driven  − All APIs of Node.js library are asynchronous, that is, non-blocking. It essentially means a Node.js based server never waits for an API to return data. The server moves to the next API after calling it and a notification mechanism of Events of Node.js helps the server to get a response from the previous API call. Very Fast  − Being built on Google Chrome's V8 JavaScript Engine, Node.js library is very fast in code execution. Single Threaded but Highly Scalable  − Node.js uses a single threaded model with event looping. Event mechanism helps the server to respond in a non-blocking way and makes the server highly scalable as opposed to traditional servers which create limited threads to handle requests. Node.js uses a single threaded program and the same program can provide service to a much larger number of requests than t...
