Using Source Generator to create simpler method overload

Question

I got a class that currently needs to be registered like this (to work reflection-free)

ViewLocator = new StrongViewLocator()
    .Register<MainWindowViewModel>(new ViewDefinition(typeof(MainWindow), () => new MainWindow()))
    .Register<AddTextDialogViewModel>(new ViewDefinition(typeof(AddTextDialog), () => new AddTextDialog()));

I want to get the equivalent of the above code generated using this simpler syntax.

ViewLocator = new StrongViewLocator()
    .Register<MainWindowViewModel, MainWindow>()
    .Register<AddTextDialogViewModel, AddTextDialog>();

How can I achieve this with Source Generator?

I'm not sure how it is relevant to Source Generators. Source Generator generates new code during the build. Here, it seems that extension method will suffice. — Vlad DX, Feb 28 '23 at 18:57

I believe an extension method will suffice.

Something like this:

public static StrongViewLocator Register<TViewModel, TWindow>(this StrongViewLocator viewLocator)
    where TWindow : new()
{
    // .Register<MainWindowViewModel>(new ViewDefinition(typeof(MainWindow), () => new MainWindow()))
    // .Register<MainWindowViewModel, MainWindow>()

    return viewLocator.Register<TViewModel>(new ViewDefinition(typeof(TWindow), () => new TWindow()))
}

really that simple? How did I miss that – Etienne Charland Feb 28 '23 at 19:47 — Etienne Charland, Feb 28 '23 at 19:47
