附加型无法与NLOG类型的引用一起编译C＃源

Question

我正在尝试使用C＃源添加PowerShell V5中的类型，该源引用NLOG v5.0.0记录库。

当我执行以下MRE时：

$source = @'
namespace Test
{
    using System;

    public class MyClass
    {
        private NLog.ILogger logger;

        public static void Run()
        {
            Console.WriteLine("Hello world!");
        }
    }
}
'@

$path = 'C:\nlog\net46\NLog.dll'
$assemblies = @($path)

Add-Type -ReferencedAssemblies $assemblies -TypeDefinition $source -Language CSharpVersion3 -ErrorAction Stop

[Test.MyClass]::Run()

我会收到以下错误：

Add-Type : (0) : Warning as Error: Reference to type 'System.Action' claims it is defined in 'c:\Windows\Microsoft.NET\Framework64\v2.0.50727\mscorlib.dll', but it could not be found
(1) : namespace Test
At C:\test.ps1:21 char:1
+ Add-Type -ReferencedAssemblies $assemblies -TypeDefinition $source -L ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidData: (Microsoft.Power...peCompilerError:AddTypeCompilerError) [Add-Type], Exception
    + FullyQualifiedErrorId : SOURCE_CODE_ERROR,Microsoft.PowerShell.Commands.AddTypeCommand

如果我在类中注释了引用NLOG类型的字段（private nlog.ilogger logger;），则MRE将成功执行。

如果add-type执行的原始代码，则在编译中剩下的字段并执行执行：

Add-Type -ReferencedAssemblies $assemblies -TypeDefinition $source -IgnoreWarnings -ErrorAction Stop

但是，实际上使用库是不足的。以下MRE的失败不同：

$source = @'
namespace Test
{
    using System;

    public class MyClass
    {
        public static void Run()
        {
            Console.WriteLine(typeof(NLog.ILogger));
        }
    }
}
'@

$path = 'C:\nlog\net46\NLog.dll'
$assemblies = @($path)

Add-Type -ReferencedAssemblies $assemblies -TypeDefinition $source -ErrorAction Stop

[Test.MyClass]::Run()

我现在会收到以下错误：

Exception calling "Run" with "0" argument(s): "Could not load file or assembly 'NLog, Version=5.0.0.0, Culture=neutral, PublicKeyToken=5120e14c03d0593c' or one of its dependencies. The
