本文介绍了为什么我的.NET应用程序需要完全信任？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！问题描述

我已经开发了.NET 3.0的应用程序，这是使用ClickOnce部署。

I've developed a 3.0 application, which is deployed using clickonce.

我想从完全信任移动到部分信任，以简化部署。

I'd like to move from full trust to partial trust to ease deployment.

我试着下的Visual Studio我的项目的安全性选项卡中的计算权限工具，答案是很清楚的：

I've tried the "Calculate Permissions" tool in the "Security" tab of my project under visual studio, and the answer is quite clear :

--------------------------- Microsoft Visual Studio --------------------------- This application requires full trust to run correctly.

不过，我已经无法弄清楚为什么完全信任是必要的。我试图更改安全设置部分信任，但应用一经推出，立即引发一个SecurityException：

However, I've not been able to figure out why full trust is required. I've tried to change the security settings to "partial trust", but the application raises a SecurityException immediately upon launch :

System.Security.SecurityException {"Request failed.", Action= "System.Security.Permissions.SecurityAction.LinkDemand" at MyNameSpace.Program.Main(String[] args) at System.AppDomain._nExecuteAssembly(Assembly assembly, String[] args) at System.AppDomain.nExecuteAssembly(Assembly assembly, String[] args) at System.Runtime.Hosting.ManifestRunner.Run(Boolean checkAptModel) at System.Runtime.Hosting.ManifestRunner.ExecuteAsAssembly() at System.Runtime.Hosting.ApplicationActivator.CreateInstance(ActivationContext activationContext, String[] activationCustomData) at System.Runtime.Hosting.ApplicationActivator.CreateInstance(ActivationContext activationContext) at System.Activator.CreateInstance(ActivationContext activationContext) at Microsoft.VisualStudio.HostingProcess.HostProc.RunUsersAssemblyDebugInZone() at System.Threading.ThreadHelper.ThreadStart_Context(Object state) at System.Threading.ExecutionContext.runTryCode(Object userData) at System.Runtime.CompilerServices.RuntimeHelpers.ExecuteCodeWithGuaranteedCleanup(TryCode code, CleanupCode backoutCode, Object userData) at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ThreadHelper.ThreadStart()

我的软件可能并不需要完全信任（我只使用https连接到Web服务器，并访问文件系统只在用户请求时，对进口/出口目的）

My software probably doesn't need full trust (I only connect to a webserver using https, and access the filesystem only upon user request, for importation/exportation purposes)

我怎么能弄清楚，为什么我的应用程序需要完全信任？

How can I figure out why my application requires full trust?

推荐答案

添加requirePermission =在App.config的configsections'假'的属性有很大帮助：

Adding the requirePermission='false' attribute in the app.config's configsections helps a lot :
