Hi There,

Is it possible to save cached data to the file system in a Silverlight 3 App (without the SaveAs Dialog)? I know it's possible to save to a steam, but we need full offline ability whereby we'll read from local files in the absence of a connection. It seems like you cannot because of the 'Sand-box' SL runs in? All the sample code I've seen looks like WinForms or WPF. A Siverlight sample would be apreciated if indeed it's possible.

Thanks
Marcus

 Silverlight 3 does not have any file system support, but you can use Isolated Storage.    The Model Explorer

     http://www.ideablade.com/DevForceSilverlight/DevForceSilverlight_ModelExplorer.aspx - http://www.ideablade.com/DevForceSilverlight/DevForceSilverlight_ModelExplorer.aspx

has an example of using isolated storage to run disconnected with a saved EntityCacheState. See the file IsolatedStorageFileFns.cs.

In Silverlight 4 Out of Browser applications, you can use the file system.  See
