# .Net

Available in Classic and VPC

This section describes how to create and use .Net(core) actions in a variety of ways, and includes application examples.

          Note

          

To compile, test, and compress .NET Core projects, you must install [.NET Core SDK](https://dotnet.microsoft.com/download)locally and set the DOTNET_HOME environment variable to the location of the dotnet executable file.

## Create action

To create an action, you must first understand the .NET action structure. .NET Core actions consist of .NET Core libraries and Main function structured as follows:

```
public Newtonsoft.Json.Linq.JObject Main(Newtonsoft.Json.Linq.JObject);
```

Create a C# project named NCP.CloudFunctions.Example.Dotnet to check an example for action creation.

```
dotnet new classlib -n NCP.CloudFunctions.Example.Dotnet -lang "C#" -f netstandard2.0
cd NCP.CloudFunctions.Example.Dotnet
```

Then install [Newtonsoft.Json](https://www.newtonsoft.com/json), [NuGet](https://docs.microsoft.com/ko-kr/nuget/what-is-nuget) packages for using json.

```
dotnet add package Newtonsoft.Json -v 12.0.1
```

Here's an example of creating an action:

1. Write an action code Hello.cs.

```
using System;
using Newtonsoft.Json.Linq;

namespace NCP.CloudFunctions.Example.Dotnet
{
    public class Hello
    {
        public JObject Main(JObject args)
        {
            string name = "stranger";
            if (args.ContainsKey("name")) {
                name = args["name"].ToString();
            }
            JObject message = new JObject();
            message.Add("greeting", new JValue($"Hello, {name}!"));
            return (message);
        }
    }
}
```
2. Run the command to publish the project contents.

```
dotnet publish -c Release -o out
```
3. Run the command to create a zip file of the published contents.

```
cd out
zip -r -0 helloDotNet.zip *
```
4. Create an action by uploading the created zip file.

- When creating an action in .NET format, you must enter the `Main`  function in the format {Assembly}::{Class Full Name}::{Method} as shown in this example.

```
NCP.CloudFunctions.Example.Dotnet::NCP.CloudFunctions.Example.Dotnet.Hello::Main
```
