title: Isolated Storage in silverlight application - non consistent behavior
body: <p>I have a silverlight application which hosted in asp.net web site.</p>
  
  <p>I store some information in .txt file isolated storage, in order to load it next time the application called.</p>
  
  <p>Here I have a strange problem: sometimes the application doesn't find the file! </p>
  
  <p>I checked what exactly happens, and discover that the isolated storage (I checked on Windows 7) composed of set of folders, their names seem as keys/guids.
  when the application doesn't find the file, for some reason it goes to another key/guid folder, not to the folder the application saved the file on!
  I read about it throughout the net, and understand that the key/guid folders created by microsoft according its security policy.</p>
  
  <p>the code I used to create the isolated storage is:</p>
  
  <p><code>IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForSite();</code></p>
  
  <p>I tried also</p>
  
  <p><code>IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForApplication()</code></p>
  
  <p>-the same problem.</p>
  
  <p>what can I do?</p>
  
  <p>I'll be glad to detail more, if necessary.</p>
  
  <p>thanks a lot!</p>
