如何显示一个WPF页或窗口，而无需等待重过程完成 [英] How to display a WPF page or window without waiting for heavy processes to finish

问题描述

我工作的一个WPF浏览器应用程序。现在的问题是，我要在beginig加载一些重服务，这会导致看到一个白色的页面，几秒钟得到加载的页面组件之前。是否有办法避免这种通过某种方式，而不必等待重进程完成加载页面？

I am working on a WPF Browser Application. The problem is that I have to load some heavy services in the beginig, this causes to see a white page for some seconds before the page components get loaded. Is there a way to avoid this somehow by loading the page without waiting for the heavy processes to finish?

下面是现在的事，我想，它没有工作：

Here is the thing I am trying now, and it didn't work:

    public Page1()
    {
        InitializeComponent();
    }

    private void Page_Loaded_1(object sender, RoutedEventArgs e)
    {
        // Initialize and configure kinect
        // This takes some seconds
    }

我的想法后，页面的所有组件已完成加载的page_loaded事件发生。但它仍然等待进程完成，我在开始时获得一个白色的页面的某些秒......

I was thinking the page_loaded event happens after all the components of the page have finished loading. But still it waits for the processes to finish and I get some seconds of a white page in the begining...
