write-script-csharp	MUST use when writing C# scripts.

CLI Commands

Place scripts in a folder. After writing, tell the user they can run:

• wmill generate-metadata - Generate .script.yaml and .lock files
• wmill sync push - Deploy to Windmill

Do NOT run these commands yourself. Instead, inform the user that they should run them.

Use wmill resource-type list --schema to discover available resource types.

C#

The script must contain a public static Main method inside a class:

public class Script
{
    public static object Main(string name, int count)
    {
        return new { Name = name, Count = count };
    }
}

Important:

• Class name is irrelevant
• Method must be public static
• Return type can be object or specific type

NuGet Packages

Add packages using the #r directive at the top:

#r "nuget: Newtonsoft.Json, 13.0.3"
#r "nuget: RestSharp, 110.2.0"

using Newtonsoft.Json;
using RestSharp;

public class Script
{
    public static object Main(string url)
    {
        var client = new RestClient(url);
        var request = new RestRequest();
        var response = client.Get(request);
        return JsonConvert.DeserializeObject(response.Content);
    }
}
