• • • • • One of the main reasons for using.NET Core is that you can run it on multiple platforms and architectures. So you can build an app that will run on Windows, but also on Linux, macOS and on different architectures like x86 and ARM.

Visual Studio 2017 for mac was launched at MS Build 2017 with many fresh and exciting features for Visual Studio developers in mac machine. Mac OS user can build apps for mobile, web, and cloud with Xamarin and.NET Core, games with Unity using Visual Studio. In the previous chapter we looked at the creation of a very simple console based C# program. In this chapter we will take this concept a step further by creating a small GUI (Graphical User Interface) based application using Visual Studio. Access to a system running Visual Studio with C# support is.

This is perfect for lots of scenarios, including desktop applications. You can learn about other reasons for using.NET Core in this article about the on and in my Pluralsight course: The.NET Ecosystem: The Big Picture. In this article, I’m going to show you how to create a simple.NET Core console application that can run on multiple operating systems.

To work through the demos in this article, make sure that you have the following installed on a computer running Windows 10: • Visual Studio 2017 any edition (update 2 or higher) • Additionally, in order to run the app on a Mac, you will need access to a Mac that is running macOS 10.12 “Sierra” or a later version. If you don’t have one, you can get access to a Mac environment using.NET Core application deployment options You can deploy.NET Core applications as framework-dependent applications and as self-contained applications. Office for mac 365 code. There are a couple of differences between the two deployment models: • Framework-dependent applications require the.NET Core framework to be installed on the machine that the app will run on. • Self-contained applications don’t, because they contain everything the app needs to run • Framework-dependent applications can run on any operating system that you install.NET Core on, without modification • In contrast, for every OS that you want a self-contained app to run on, you need to publish an OS-specific version. How to create an app for multiple operating systems Now that we know there are two different deployment options for.NET Core, let’s explore how to use those to run a.NET Core app in multiple operating systems.

To explore this, we’ll create two simple.NET Core console applications and run those on Windows and on macOS. I’ve already created this sample in a GitHub repository that you can.

We’ll create the applications using Visual Studio 2017. This is technically not needed, as you can create.NET Core applications with many different IDEs and even with. Choose the that you are most comfortable with. Framework-dependent app First, we’ll create a framework-dependent app. We do this in Visual Studio 2017 with all the latest updates (at the moment, I’m on 15.5.2).

• In Visual Studio, click File > New Project and select.NET Core • Now select the Console App (.NET Core) project type and create it • Navigate to Program.cs. Out of the box, it will write Hello World! To the console • Add Console.ReadLine(); below the Hello World line, to keep the console window open when the app runs That’s it! This app will run on every o.

Self-contained app Next, we’ll create a self-contained app. This is very similar to creating a framework-dependent app, but contains one extra step: • In Visual Studio, click File > New Project and select.NET Core • Now select the Console App (.NET Core) project type and create it • Navigate to Program.cs. Out of the box, it will write Hello World!
