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

## CLI Commands

Place scripts in a folder. After writing, run:
- `wmill script generate-metadata` - Generate .script.yaml and .lock files
- `wmill sync push` - Deploy to Windmill

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

# C#

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

```csharp
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:

```csharp
#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);
    }
}
```
