Question

我正在尝试在Azure Functions v2中使用.NET Core编写Function App。使用Nuget的Microsoft.Powershell.SDK程序包（.NET Core PowerShell运行时必需）时，我无法使用Visual Studio将System.Management.Automation库与我的Function App复制到bin中。

这会导致以下错误：

System.Private.CoreLib: Exception while executing function: Function1. TestPowershellInFunction: Could not load file or assembly 'System.Management.Automation, Version=6.1.1.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. The system cannot find the file specified. System.Private.CoreLib: Could not load the specified file.

我已经在现有的Azure函数和新的解决方案中重现了这一点，只需创建一个Timer函数并添加以下代码段即可：

PowerShell shell = PowerShell.Create();
IEnumerable<PSObject> result = shell.AddScript("Write-Output 'Hello, World!'").Invoke();

foreach(PSObject line in result)
{
    log.LogInformation(line.ToString());
}

这在安装了PowerShell Nuget的新控制台应用程序上有效，但是将其添加到功能应用程序时出现错误。我确实注意到System.Management.Automation不会通过常规控制台应用程序放入bin目录，但是我不确定如何解释这一点。我知道这是一个系统库，但是除非安装了Nuget，否则我将无法使用它，因此我不知道这是否是特例。在这两种情况下，我都使用PowerShell Nuget的v6.1.1。

这是Function v2的已知错误吗？还是我错过了什么？

已知issue是Function无法正确加载运行时程序集（[FunctionProject]\bin\Debug\netcoreapp2.1\bin\runtimes）。

解决方法是手动将程序集移动到输出目录bin。右键单击您的功能项目，然后单击Edit <FunctionProject>.csproj。添加以下项目以实现我们的目标。

 <PropertyGroup>
    <SDKVersion>6.1.1</SDKVersion>
    <SDKPlatform>win-x86</SDKPlatform>

请注意，在我这边（Win10），microsoft.management.infrastructure设置为win10-x86，您可能需要根据您的PC平台进行更改。程序集是x86，因为VS默认情况下使用x86 Function CLi，除非我们需要使用x64，否则我们不必担心。
