.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 - MVC Design Pattern

The MVC (Model-View-Controller) design pattern is a design pattern that's actually been around for a few decades, and it's been used across many different technologies, everything from Smalltalk to C++ to Java and now in C# and .NET as a design pattern to use when you're building a user interface. The MVC design pattern is a popular design pattern for the user interface layer of a software application. In larger applications, you typically combine a model-view-controller UI layer with other design patterns in the application, like data access patterns and messaging patterns. These will all go together to build the full application stack. The MVC separates the user interface (UI) of an application into the following three parts − The Model  − A set of classes that describes the data you are working with as well as the business logic. The View  − Defines how the application’s UI will be displayed. It is a pure HTML which decides how the UI is going to loo...
