C# Resources

Server-side C# is preview. The current server binary executes only JavaScript resources server-side (server/src/CServer.cpp); it does not load a type = "csharp" resource yet. The C# SDK (sdk/Varion.SDK) ships in the kit as a preview surface. Use type = "js" for server logic today.

The working .NET path right now is client-side: client-type = "csharp" via the .NET client host (sdk/dotnet-host), additive to the primary JS/WebView2 client backend.

resource.toml (preview):

enabled = true
type = "csharp"
main = "MyResource.dll"
client-type = "none"

If main is omitted, the default is <resource>.dll.

Minimal resource (preview SDK)

using Varion;

public sealed class Main : Resource
{
    public override void OnStart()
    {
        varion.Log("resource started");
    }

    public override void OnStop()
    {
        varion.Log("resource stopped");
    }
}

Common API (preview SDK surface)

• varion.OnPlayerConnect
• varion.OnPlayerDisconnect
• varion.OnClient
• varion.OnClientRpc
• varion.EmitClient
• varion.EmitAllClients
• varion.CreateVehicleEntity
• varion.CreatePedEntity
• varion.CreateObjectEntity
• varion.CreateVirtualEntityGroup
• varion.CreateVirtualEntity
