我正在嘗試從 vb.net 項目訪問 c# 方法。c#項目有以下代碼：using System;using System.Collections.Generic;using System.Linq;using System.Text;using MeF.Client;public class LoginClass{    // lines of code that are giving errors  (when commented there’s no error)    private ServiceContext context = new ServiceContext();    public string etin;    public string appSysId;    static void Main(string[] args)       {         LoginClass.CreateServiceContext();    }    //bla, bla, bla}vb.net 項目有這個：Imports AimEFileCorePublic Class Form1    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load    End Sub    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click        Dim Process As New AimEFileCore.LoginClass        Process.CreateServiceContext()    End Sub運行代碼時出現以下錯誤System.IO.FileNotFoundException：“無法加載文件或程序集“MeFWCFClient，Version=1.0.0.0，Culture=neutral，PublicKeyToken=null”或其依賴項之一。該系統找不到指定的文件引用了 Mef dll！當我評論上面三行時，它就像一個魅力。
