3. Commands - JamesRandall/AzureFromTheTrenches.Commanding GitHub Wiki

Applies to v5.0.0 and higher. See revision history for documentation for prior versions.

Commands are serializable C# classes that must implement one of the below interfaces:

Neither interface require any methods or properties to be implemented and are simply used to identify the commands within the framework and to provide type safety where a result is required.

Additionally a command may optionally implement the IIdentifiableCommand interface if it is able to provide a universally unique ID (i.e. an ID that is unique within the entire scope and lifetime of your application and it's data stores - for example a UUID). If implemented this ID will be used in audit operations.

public class RegisterUserCommand : ICommand
{
    public string Username { get; set; }
    public string Email { get; set; }
}

public class GetUserQuery : ICommand<User>
{
    public Guid UserId { get; set; }
}

public class UpdateUserCommand : ICommand<ValidationResponse>, IIdentifiableCommand
{
    public string CommandId { get; set; } // the get is required by IIdentifiableCommand
    public Guid UserId { get; set; }
    public string Username { get; set; }
    public string Email { get; set; }
}
