Question

我试图从.NET核心api向Exchange发出一些远程请求，但是遇到一些问题，无法找到解决方案。

我创建了一个单例模式，因此每个用户只能有一个powershell会话，每当我必须打电话来交换时，我都会检索该会话。问题是，当我尝试创建运行空间并且无法运行任何命令时，出现System.IO.FileNotFoundException'和System.Management.Automation.dll错误。

我将api托管在Windows 10的本地IIS中，并且使用.NET Core 2.2。如果我直接向IIS Express发出请求，则在Visual Studio中运行代码时不会出现任何错误，但在向IIS站点发出请求时确实会出现异常。

任何帮助将不胜感激！

谢谢！

我尝试在本地创建运行空间并连接到Exchange，但是我也尝试远程连接并保存该配置，因此我只需要导入会话即可。

我们还尝试将.net核心更新为3版本，但是我们没有运气。

// this is how I retrive the sessíon from the singleton --
public Powershell GetSession(string usuario, string password)
{
    PSCredential credenciales = Powershell.CrearCredenciales(usuario, password);
    Powershell powershell;
    if (diccionarioSesionesPowershell.ContainsKey(credenciales))
    {
        powershell = diccionarioSesionesPowershell[credenciales];
        bool sesionValida = powershell.EsValida();
        if (!sesionValida)
        {
            powershell.InicializarRunspace();
        }
    }
    else
    {
        powershell = new Powershell(credenciales, Logger);
        powershell.CrearRunspace();
        diccionarioSesionesPowershell.Add(credenciales, powershell);
    }
    return powershell;
}





// this is the singleton config in startup
services.AddSingleton<PilaPowershell>();




// this is how I save my remote session so I can import it later
private Runspace Runspace{get; set;}

public bool InicializarRunspace()
{
    bool resultado = false;

我找到了解决问题的方法。创建api时，我使用nuget下载了powershell sdk，但是当我使用该SDK发布它时，IIS无法访问所需的依赖项。所以我卸载了SDK，而是在PC上安装了powershell 6，并在程序集中链接了依赖项，然后就可以了！

Powershell运行空间实例化错误：找不到System.Management.Automation
