Multi Threaded Web Browsing WPF Application in VB.NET
In this article you will see how to create a multi threaded web browsing WPF application.
Now a days multi-threaded web browse applications become increasingly popular due to the advances of the Microsoft framework. Multi-threading is the ability for an application to perform more than one execution simultaneously. It can greatly improve the responsiveness and efficiency of an application.
Sample Code
<Window x:Class="WpfApplication1.Window1"
