Windows Phone development (25): starter and selector-webbrowsertask to: http://blog.csdn.net/tcjiaan/article/details/7404770

As you can see from the name, this guy just opens the browser and browses the specified page.

 

It has two identical attributes: The URI attribute is of the system. Uri type, which is a newly written attribute;

The URL is of the string type, but if this attribute is used, a warning "expired" will be issued, so we recommend that you use the former.

 

In the following example, after clicking the button, the Web browser is opened and the address entered in the text box is located. However, the two attributes mentioned above are used respectively. After the program runs, you will find that the effect is the same.
