Using .NET Core in Visual Studio Code

Using .NET Core in Visual Studio Code

.NET Core provides a fast and modular platform for creating server apps that run on Windows, Linux, and macOS. Use Visual Studio Code with the C# and F# extensions to get a powerful editing experience with C# IntelliSense, F# IntelliSense (smart code completion), and debugging.

Prerequisites

Install the following:

.NET Core SDK. The SDK also includes the Runtime.
The C# extension from the VS Code Marketplace.
The F# extension (Ionide) from the VS Code Marketplace.

Create a C# “Hello World” app

Initialize a C# project:
- Open a terminal/command prompt and navigate to the folder in which you’d like to create the app.
- Enter the following command in the command shell:
```
  dotnet new console
```
When the project folder is first opened in VS Code:
- A “Required assets to build and debug are missing. Add them?” notification appears at the bottom right of the window.
- Select Yes.
Run the app by entering the following command in the command shell:
```
dotnet run
```

Watch a video tutorial for further C# setup help on Windows, macOS, or Linux.

Create an F# “Hello World” app

Initialize an F# project:
- Open a terminal/command prompt and navigate to the folder in which you’d like to create the app.
- Enter the following command in the command shell:
```
dotnet new console -lang F#
```
Once it completes, open the project in Visual Studio Code:
```
code .
```
Run the app by entering the following command in the command shell:
```
 dotnet run
```
