I see PRISM declaring the following constructor, and I don't understand what's that "o" being used with the lambda function that serves as the second parameter when the base constructor is called:
public DelegateCommand(Action<T> executeMethod)
: this(executeMethod, (o)=>true)
{
}
I'd appreciate an explanation.
It calls this constructor:
DelegateCommand<T>(Action<T>, Func<T, Boolean>)
Passing a lambda that always returns true as the second parameter.
