What, where, why
I need to fast forward past several planned blog topics to establish a context for this one:
- I'm working on a legacy VB6 app that is about to get some ddd, messaging love in the process of moving off the VB6 platform.
- I've landed on using the Lokad DSL tool (Github) for defining messages.
The Lokad dsl tool does what it says on the box: It lets you define immutable, datacontract serializeable, message classes. But without all the mind numbing typing normally required to write out such classes in C#.
DSL code:
AddSecurityPassword?(SecurityId id, string displayName, string login, string password)
Becomes c# code:
[DataContract(Namespace = "Sample")]
public partial class AddSecurityPassword : ICommand<SecurityId>
{
[DataMember(Order = 1)] public SecurityId Id { get; private set; }
[DataMember(Order = 2)] public string DisplayName { get; private set; }
[DataMember(Order = 3)] public string Login { get; private set; }
[DataMember(Order = 4)] public string Password { get; private set; }
AddSecurityPassword () {}
public AddSecurityPassword (SecurityId id, string displayName, string login, string password)
{
Id = id;
DisplayName = displayName;
Login = login;
Password = password;
}
}
But I needed more
There is another branch of c# coding that requires a lot of typing:
COM interop code.
