问题描述

我使用 Entity Framework、SQL Server 2000、Visual Studio 2008 开发了一个应用程序和企业图书馆.

I have developed an application using Entity Framework, SQL Server 2000, Visual Studio 2008 and Enterprise Library.

它在本地工作得很好，但是当我将项目部署到我们的测试环境时，我收到以下错误:

It works absolutely fine locally, but when I deploy the project to our test environment, I am getting the following error:

无法加载一种或多种请求的类型.检索 LoaderExceptions 属性以获取更多信息

推荐答案

我通过将项目引用的 Copy Local 属性设置为 true 解决了这个问题.

I solved this issue by setting the Copy Local attribute of my project's references to true.
