Dll 无法加载文件或程序集mscorlib

我是NetCore的新手，我尝试使用以下代码动态加载dll：

public void LoadDll()
{
    try
    {
        var dllPath = @"C:\Temp\dynamic.dll";

        var asl = new AssemblyLoader();
        var asm = asl.LoadFromAssemblyPath(dllPath);

        var type = asm.GetType("MyNamespace.MyClass");
        dynamicInstance = Activator.CreateInstance(type);
    }
    catch (Exception ex)
    {

    }
}

public class AssemblyLoader : AssemblyLoadContext
{
    // Not exactly sure about this
    protected override Assembly Load(AssemblyName assemblyName)
    {
        var deps = DependencyContext.Default;
        var res = deps.CompileLibraries.Where(d => d.Name.Contains(assemblyName.Name)).ToList();
        var assembly = Assembly.Load(new AssemblyName(res.First().Name));
        return assembly;
    }
}

调用asm.GetType方法时会引发异常：

“无法加载文件或程序集'mscorlib，版本=4.0.0.0，区域性=neutral，PublicKeyToken=b77a5c561934e089'。操作在当前状态下不合法。（HRESULT的异常：0x80131509）“源：System.Private.CoreLib”

这是我的project.json：

    "dependencies": {
    "Microsoft.NETCore.App": {
      "version": "1.0.1",
      "type": "platform"

      }
    },

    },

    "runtimeOptions": {

      }
    },

    },

    "scripts": {

    }
}

有人能帮我吗？这是一个很常见的问题。从.NET Core 1.1开始，您不能加载为.NET Framework构建的库（它们基于mscorlib），只能加载使用PCL构建的库

检查您尝试加载的程序集

.NET Core 2.0将讨论此主题
