Constructor dependency injection for blazor partial classes

[msschl]

It would be nice to have constructor based dependency injection for blazor partial classes.

E.g.

namespace Blazor.Pages
{
    public partial class Index
    {
        private readonly string testMessage;

        public Index(IServiceA service)
        {
            this.testMessage = service.GetMessage();
        }
    }
}
