问题描述
我发表了一些客户的Silverlight应用程序。我有问题发布更新。
I have a Silverlight app published for some customers. I am having problems issuing updates.
我想，当一个用户加载的网页开始，如果他们的应用程序存储容量超过上一次的网站更新，那么这个发生。这将使我的申请工作。
I would like for when a user loads the webpage initially, if their Application Storage is older than the last time the site was updated, then this happens. This will make my application work.
于是，两个问题：
-
我如何检查是否用户存储的应用程序存储容量超过最后更新Silverlight的网站？
How can I check if the users stored Application Storage is older thanthe last update to the Silverlight site?
如何删除应用程序存储的网站？
How can I delete the Application Storage for the site ?
我已经打过电话：
using( var store = IsolatedStorageFile.GetUserStoreForApplication() ) {
store.Remove();
}
using( var store = IsolatedStorageFile.GetUserStoreForSite()) {
store.Remove();
}
在 App.xaml.cs 文件，但这些似乎都在显示的页面上没有任何影响 - 应用程序存储没有完全清除。
in the App.xaml.cs file, but these seem to have no effect on the displayed page - the Application Storage is not fully cleared.

这code进去的应用程序，以检查是否有和更新您的SL应用程序，我不知道这是否帮助，但如果你只是想要做的事与IsolatedStorageFile当有更新它应该是你想要什么：
this code go in app to check if there's and update to your SL application I don't know if it help but if you just want to do something with that IsolatedStorageFile when there's update it should be what you want :
Application.Current.CheckAndDownloadUpdateAsync();
Application.Current.CheckAndDownloadUpdateCompleted += new CheckAndDownloadUpdateCompletedEventHandler(Current_CheckAndDownloadUpdateCompleted);
private void Current_CheckAndDownloadUpdateCompleted(object sender, CheckAndDownloadUpdateCompletedEventArgs e)
{
if (e.UpdateAvailable)
{
}
}
