How to take advantage of browser caching of XAPS

Question

I have a Silverlight Application that currently downloads XAPs on demand using Package.DownloadPackageAsync() from the System.ComponentModel.Composition.Packaging namespace.

As far as I can tell this circumvents any sort of browser caching of XAPS that may take place. Does anyone know how to take advantage of browser caching using on demand downloads ? The only thing i can think of is doing my own caching of XAPs in isolated storage.

Thanks,

@Graeme: Is MEF an additional SDK? There is no Packaging namespace in the Silverlight 4 Beta documentation on MSDN that I can see? — AnthonyWJones, Mar 05 '10 at 17:37
Package was removed from the Beta build. It was refactored and re-added as the DeploymentCatalog in the most recent build. See: http://mtaulty.com/CommunityServer/blogs/mike_taultys_blog/archive/2010/02/24/mef-silverlight-and-the-deploymentcatalog.aspx — Joe McBride, Mar 08 '10 at 06:14

According to Glenn Blocks latest post: "We are looking into cached assembly support in the future."

That being said, aside from caching the XAP in isolated storage, if you are running OOB you could cache the XAP manually on the local system.

I'm glad they are thinking about this, meanwhile i guess i'll implement the Isololated storage cache. Good blog post, thanks for the answer. – F.A.B Mar 08 '10 at 13:09
