Both WPF and Silverlight are tools for building rich user interfaces (animation, drawing, layout). They all use XAML to lay out, and since Silverlight2, they have supported oops. The main difference is:

Wpf:

1. Mainly used in desktop systems, but its components can be used by the ASP.

2. Can run directly (EXE) separately;

3. dependent on Windows;

4. Can be used by desktop and browser;

5. Can interact directly with the database (non-WPF browser application);

6. No browser plugin required;

7. Use root tags, such as Window,page,usercontrol.

Silverlight:

for website development;

Integrate its output into the webpage by using a component;

You can start from the desktop by enabling the Out of browser feature (starting from SILVERLIGHT3);

Do not rely on windows, there is a Linux implementation (moonlight);

Cannot access database directly, need to use WCF or webservice;

Need to install browser plugin;

The root is marked as usercontrol,page.

7. Talk about the Silverlight runtime?

The Silverlight runtime is used to download the. xap file from the server side and to display the removal of the Silverlight content to the Web page. It is a browser plugin that only installs the plugin to allow the browser to display Silverlight content properly.

8. What is isolated storage (Isolated Storage)?

Silverlight uses isolated storage to store data in a virtual file system in a hidden folder on the machine, and to divide the data into two parts:

Part II: Contains the actual data.

Each Silverlight application is assigned a separate partition with a default limit of 1MB.
