当 Net 版本不是 Net4 时，我的应用程序运行良好。如果我从头开始创建基于 Windows 7 的新服务器，它会继续完美运行。配置权限，然后离开。
但是（总是有一个但是......），我的客户有一个现有的服务器，当我迁移到 Csla4 和 Net4 时，应用程序甚至没有启动。我的“干净”服务器和他的“旧版但升级”服务器上的所有权限似乎都是相同的。但是客户端收到一个安全错误：
System.Security.SecurityException: Request failed.

The action that failed was:
Demand
The type of the first permission that failed was:
System.Security.PermissionSet
The demand was for:
<PermissionSet class="System.Security.PermissionSet"
version="1"
Unrestricted="true"/>
The only permitted permissions were:
<PermissionSet class="System.Security.NamedPermissionSet"
version="1"
Name="Internet"
Description="Default rights given to Internet applications">
<IPermission class="System.Security.Permissions.FileDialogPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"

<IPermission class="System.Security.Permissions.IsolatedStorageFilePermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"

</PermissionSet>
The method that caused the failure was:
System.Object CreateSectionWithRestrictedPermissions(System.Configuration.RuntimeConfigurationRecord, System.Configuration.FactoryRecord, System.Configuration.SectionRecord, System.Object, System.Configuration.ConfigXmlReader)
我正在研究 Net4 中 ASPNET 安全性的变化，我非常困惑。
有没有其他人遇到过这个问题并且可以指出我正确的方向？重复一遍，该应用程序在我从头开始创建的远程环境中完美运行，但在更新的旧服务器中无法正常运行。
