On July 6, June 14, Microsoft upgraded Silverlight 4 to 4.0.60531.0. The patch package for this version is Update for Microsoft Silverlight (KB 2512827 ).". Runtime upgrade through the Silverlight Official Website: http://www.silverlight.net

This version mainly fixes the following problems:

1. fixed security issues caused by remote code execution;

2. fixed the problem that the keyboard cannot be used to activate the Silverlight button event under Apple OS X 10.6 and Firefox 4.0;

3. Fixed the Exception error caused by dragging the Silverlight application to the full screen mode of the secondary display when it runs in Firefox 4.0 on multiple monitors;

4. Solved the early Silverlight 4 version in IE8. When polling duplex is bound, the HTTP stack uses the BrowserHttpWebRequest object. When ServerPollTimeout times out, Silverlight will cause an exception and error;

5. Solve the memory leakage caused by DependencyObject dependency in the template of static resource files;

 

Features added in this version:

Add the InjectClientInformation attribute to the LicenseAcquirer class, which is located in the System. windows. media namespace, which is used to inject a data set into the domain name or computer to be accessed. The data set contains a set of base64-encoded data certificate verification strings with Hash values.

Silverlight developers can upgrade the Client Version as required by the project.
