Silverlight 3 浏览器外更新

发布于 2024-08-01 18:05:46 字数 133 浏览 3 评论 0原文

我有一些正在使用 silverlight 应用程序的用户，但在发布新版本时没有收到更新。这不是应该是自动的还是我在某个地方缺少一个选项？我也开始认为 XAP 文件可能被缓存了，我知道如何防止这种情况发生。

有什么想法吗？

仅当开发人员执行 CheckAndDownloadUpdateAsync() 调用时，它才会自动更新。查看更新：http://timheuer.com/blog/archive/2009/07/10/silverlight-3-released-what-is-new-and-changed.aspx#oob

您需要编写几行代码。

如果您熟悉“一键式”部署，那么您习惯的某些选项在 Silverlight 中并不存在。您需要自己编写代码。

http://nerddawg.blogspot.com/2009 /07/silverlight-out-of-browser-apps-how.html

    private void Application_Startup(object sender, StartupEventArgs e)
    {
        this.RootVisual = new MainPage();

        if (Application.Current.IsRunningOutOfBrowser)
        {
            Application.Current.CheckAndDownloadUpdateAsync();
        }

然后在您的 App() 构造函数中：

    Application.Current.CheckAndDownloadUpdateCompleted += 
    new CheckAndDownloadUpdateCompletedEventHandler(Current_CheckAndDownloadUpdateCompleted);

和一个事件处理程序：

 void Current_CheckAndDownloadUpdateCompleted(object sender, CheckAndDownloadUpdateCompletedEventArgs e)
    {
        // http://nerddawg.blogspot.com/2009/07/silverlight-out-of-browser-apps-how.html
        if (e.UpdateAvailable)
        {
            MessageBox.Show("The application has been updated! Please close and reopen it to load the new version.");
        }
        else if (e.Error != null && e.Error is PlatformNotSupportedException)
        {
            MessageBox.Show("An application update is available, " +
                "but it requires a new version of Silverlight. " +
                "Please contact tech support for further instructions.");
        }
    }

You need to write a few lines of code.

If you're familiar with 'one click' deployment then some of the options you're used to don't exist in Silverlight. You need to write the code yourself.

    private void Application_Startup(object sender, StartupEventArgs e)
    {
        this.RootVisual = new MainPage();

        if (Application.Current.IsRunningOutOfBrowser)
        {
            Application.Current.CheckAndDownloadUpdateAsync();
        }

and then in your App() constructor :

    Application.Current.CheckAndDownloadUpdateCompleted += 
    new CheckAndDownloadUpdateCompletedEventHandler(Current_CheckAndDownloadUpdateCompleted);

and an event handler :

 void Current_CheckAndDownloadUpdateCompleted(object sender, CheckAndDownloadUpdateCompletedEventArgs e)
    {
        // http://nerddawg.blogspot.com/2009/07/silverlight-out-of-browser-apps-how.html
        if (e.UpdateAvailable)
        {
            MessageBox.Show("The application has been updated! Please close and reopen it to load the new version.");
        }
        else if (e.Error != null && e.Error is PlatformNotSupportedException)
        {
            MessageBox.Show("An application update is available, " +
                "but it requires a new version of Silverlight. " +
                "Please contact tech support for further instructions.");
        }
    }
