dotnet new creates a new application, console is the type of application to create, and -o hwapp sets an output directory of hwapp (short for Hello World app). cd hwapp moves into the newly created app directory.
The template for console applications created a Program.cs file, with code to write "Hello World" to the console.
using System;
namespace hwapp
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Hello World!");
}
}
}Finally, dotnet run will run your app.
You've built and run your first .NET app.
Visual Studio is a fully-featured integrated development environment (IDE) for developing .NET apps on Windows.
Select the .NET Core cross-platform development workload during installation.
While you wait for Visual Studio to install, try our in-browser tutorial.
In order to install .NET from Red Hat on RHEL, you first need to enable the .NET channel which is available under your RHEL 7 subscription. You also need to ensure that your system supports enabling software collections via the scl tool.
For help on registering your machine to get access to the channel see the Chapter 1 of the .NET Core 2.0 Getting Started Guide at Red Hat.
Now you can install the .NET Core SDK and then enable the .NET software collection.
For additional help and guidance on installing and enabling .NET on RHEL, see the .NET Core Getting Started Guide at Red Hat.
