实体框架不适用于已发布的WCF服务 [英] Entity Framework does not work on published WCF service

问题描述

我有一个托管在网站上的WCF服务，但是我可以使Entity Framework与其一起使用.一切在本地都可以正常运行，但不能在服务器上运行.我收到以下异常:

I have an WCF service that is hosted on a web site, but i can get Entity Framework to work with it. Everything works fine locally but not on the server. I get the following exception:

Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.

很抱歉，我无法提供更多详细信息，但这是因为我不知道发生了什么.如果需要其他任何详细信息来解决此问题，请告诉我，我将其发布.我检查了以下内容:

1. .net版本在所有项目上都相同.
2.在所有引用上，本地复制"均设置为"True".

I''m sorry that I''m not able to provide more details, but this is because i don''t know what is going on. If there are any other details needed to solve this problem please let me know, i will post them. I have checked the following:

1. .Net version is the same on all projects.
2. Copy Local is set to "True" on all references.

推荐答案

最后解决了它.我的图书馆项目引用了System.Web.Mvc，因此我不得不将以下dll复制到Bin文件夹中:

Microsoft.Web.Infrastructure.dll
System.Web.Mvc.dll
System.Web.Razor.dll
System.Web.WebPages.Deployment.dll
System.Web.WebPages.dll
System.Web.WebPages.Razor.dll

我不明白的是，如果我在发布网站时在图书馆项目中的引用上将本地副本设置为"true"，为什么不包含该副本.

Finally solved it. My library project referenced System.Web.Mvc so i had to copy the following dll''s to the Bin-folder:

Microsoft.Web.Infrastructure.dll
System.Web.Mvc.dll
System.Web.Razor.dll
System.Web.WebPages.Deployment.dll
System.Web.WebPages.dll
System.Web.WebPages.Razor.dll

What i don''t understand is, if i set the copy local to "true" on a reference inside a library project why isn''t it included, when i publish the web site.
