ARC0003: Handle() must be on [Command] type

Rule

Public Handle() methods that operate on a [Command] type must be declared on the command type itself.

Severity

Error

Example

Violation

using Cratis.Arc.Commands.ModelBound;

[Command]
public record CreateOrder(string OrderId);

public class CreateOrderHandler
{
    // ARC0003: Handle() for CreateOrder is not on the command type itself
    public void Handle(CreateOrder command)
    {
    }
}

Fix

using Cratis.Arc.Commands.ModelBound;

[Command]
public record CreateOrder(string OrderId)
{
    public void Handle()
    {
    }
}
