In addition to supporting C# and F#, .NET Core 2.0 also supports Visual Basic.

Visual Basic

With version 2.0, .NET Core now supports Visual Basic 2017. You can use Visual Basic to create the following project types:

  • .NET Core console apps
  • .NET Core class libraries
  • .NET Standard class libraries
  • .NET Core unit test projects
  • .NET Core xUnit test projects

For example, to create a Visual Basic Hello World application, open a console window, create a directory for your project, and make it the current directory.

Enter the following command on console.

dotnet new console -lang vb.

The command creates a project file with a .vbproj file extension, along with a Visual Basic source code file named Program.vb.


The Program.vb file contains the source code to write the string "Hello World!" to the console window.

Imports System

Module Program
    Sub Main(args As String())
        Console.WriteLine("Hello World!")
    End Sub
End Module

Enter the command dotnet run. The .NET Core CLI automatically compiles and executes the application, which displays the message "Hello World!" in the console window.

Support for C# 7.1

.NET Core 2.0 supports C# 7.1, which adds a number of new features, including:

  • The Main method, the application entry point, can be marked with the async keyword.
  • Inferred tuple names.
  • Default expressions.
