从"开始菜单"链接单击"开始时间"

Question

我使用clickonce 3.5部署了大应用程序(在600个文件中190 MB).安装此应用程序后,我从位于"开始"菜单中的链接运行它,但显示我的启动画面需要4-12秒.从.exe文件运行此应用程序时,1秒后可以看到启动画面.我的应用程序不使用自动更新(Clickonce更新是从源代码手动完成的)

我尝试使用dotTrace来分析这个应用程序,以找出在启动过程中需要这么长时间的内容并找出答案

IActContext System.Deployment.Internal.Isolation.IsolationInterop.CreateActContext(IDefinitionAppId)

花了很多时间

这是完整的子树:

如何缩短申请的开始时间？这非常关键,因为有时用户必须等待超过12秒才能看到启动画面

Answer 1

看起来很大一部分时间都花在确定应用程序的信任级别上。您是否尝试过完全信任地部署此应用程序，看看是否会缩短时间？
