＆QUOT;动态操作只能在同质的AppDomain＆QUOT执行;同时发动PowerShell的错误 [英] "dynamic operations can only be performed in homogenous appdomain" error while launching PowerShell

问题描述

我有我试图从WCF REST service.I执行PowerShell脚本现在用的是 System.Management.Automation 和系统。 Management.Automation.Runspaces 组件。

I have a powershell script that I am trying to execute from WCF REST service.I am using the System.Management.Automation and System.Management.Automation.Runspaces assemblies.

在C＃code是这样的：

The C# code looks like this:

Command command = new Command(path);
command.Parameters.Add(param);
RunspaceConfiguration runspaceConfiguration = RunspaceConfiguration.Create();
using (Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfiguration))
{
    runspace.Open();
    ... other code
}

此错误这里发生一次我试图执行的公开声明：

This error happens here once I try to execute the open statement:

动态操作只能在均质的AppDomain进行。

Dynamic operations can only be performed in homogenous AppDomain.

我已经找了又找，但没有奏效。我曾尝试加入这一行到我的web.config：
 
但它并没有为我做任何事情。

I have looked and looked but nothing worked. I have tried adding this line to my web.config: But it didn't do anything for me.

你有什么想法？

I just googled that error and it seemed to be related to legacyCasPolicy being set to true as discussed here and here. It turns setting it to false resolved your issue as well. Detailed information about this configuration element can be found here.
