当Net版本不是Net4时，我的应用程序运行得很漂亮。如果我从头开始创建一个基于Windows 7的新服务器，它将继续完美运行。配置权限，然后离开。
但是（总有一个但是......），我的客户有一个现有的服务器，当我转移到Csla4和Net4时，应用程序甚至都没有启动。在我的“干净”服务器和他的“遗留但升级”的服务器上，所有权限似乎都是相同的。但客户端出现安全错误：
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"
version="1"

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

<IPermission class="System.Security.Permissions.SecurityPermission, 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，并且非常困惑。
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，但不在更新的旧服务器中。
答案 0 :(得分：0)
我认为服务器在web.config中配置为“中等信任”。据我所知，CSLA要求“完全信任”来克隆业务对象。
如果这不是问题，您可以尝试将服务器添加到Windows注册中的客户端受信任区域
[HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Internet Settings \ ZoneMap]
