Tip: The DLL files in the Silverlight blend SDK can also be cached using the application library.

I believe many of my friends have used the functions of the blend SDK when developing Silverlight, but referencing the DLL in the blend SDK will make our applicationProgramThe xap package increases, affecting user experience.

The "application library Caching" function of Silverlight can reduce the size of xap files. After the first loading, the files are cached and read from the cache when users access the files again, the loading speed is improved, but when the xap of our application changes, the user end does not need to update all DLL files, which is a good function. However, by default, the DLL contained in the blend SDK is not packaged outside the xap file because there is no extmap configuration file (actually an XML file, so I wrote several extmap configuration files (click to download) and put them in the same directory of the blend SDK DLL.
