[Proposal] Further enhance typed binding support by adding BindCommand

See original GitHub issue

Feature name

Further enhance typed binding support by adding BindCommand

Link to discussion


Progress tracker


The work carried out in #155 didn’t bring full typed binding support up to par with the existing binding support. We want to add in the BindCommand implementation to match the old binding functionality.


Quicker bindings means quicker apps.

Detailed Design

public static TBindable BindCommand<TBindable, TBindingContext, TSource>(
    this TBindable bindable,
    Func<TBindingContext, TSource> getter,
    TSource? source = null,
    string? parameterPath = Binding.SelfPath,
    object? parameterSource = null) where TBindable : BindableObject

Usage Syntax

new Button().BindCommand(static (ViewModel vm) => vm.SubmitCommand);

static is a recommended because it gives a performance boost to anonymous methods:

You don’t have to use static anonymous methods, but it is recommended.
