## Give it a try today

Create a C# project called Apache.OpenWhisk.Example.Dotnet:

```bash

dotnet new classlib -n Apache.OpenWhisk.Example.Dotnet -lang "C#"

cd Apache.OpenWhisk.Example.Dotnet

```

Install the [Newtonsoft.Json](https://www.newtonsoft.com/json) NuGet package as follows:

```bash

dotnet add package Newtonsoft.Json -v 13.0.1

```

Now create a file called `Hello.cs` with the following content:

```csharp

using System;

using Newtonsoft.Json.Linq;

namespace Apache.OpenWhisk.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);

        }

    }

}

```

Publish the project as follows:

```bash

dotnet publish -c Release -o out

```

Zip the published files as follows:

```bash

cd out

zip -r -0 helloDotNet.zip *

```

Create the action

```bash

wsk action update helloDotNet helloDotNet.zip --main Apache.OpenWhisk.Example.Dotnet::Apache.OpenWhisk.Example.Dotnet.Hello::Main --kind dotnet:6.0

```

For the return result, not only support `dictionary` but also support `array`

So a very simple `hello array` function would be:

```csharp

using System;

using Newtonsoft.Json.Linq;

namespace Apache.OpenWhisk.Tests.Dotnet

{

    public class HelloArray

    {

        public JArray Main(JObject args)

        {

            JArray jarray = new JArray();

            jarray.Add("a");

            jarray.Add("b");

            return (jarray);

        }

    }

}

```

And support array result for sequence action as well, the first action's array result can be used as next action's input parameter.

So the function can be:

```csharp

using System;

using Newtonsoft.Json.Linq;

namespace Apache.OpenWhisk.Tests.Dotnet

{

    public class HelloPassArrayParam

    {

        public JArray Main(JArray args)

        {

            return (args);

        }

    }

}

```
