Silverlight reduces the size of the XAP

When a Silverlight project references a number of DLLs, the load is slow, and the size of the XAP package can be reduced in the following way

Tick "Reduce the XAP size by using the application library cache", after which the VS automatically packs the Microsoft itself and the external references unchanged DLLs into a zip compression format,

But this will also produce a lot of such zip compressed files, we can compress such zip files corresponding to the DLL in a zip compressed file, and then renamed.

Open the XAP package in the bin directory with WinRAR to view the AppManifest.xaml file

Extract the AppManifest.xaml file and leave only one line below the <Deployment.ExternalPart> node.

Replace the name in source with the modified ZIP file name (for example, Newfile.zip).
