我的目标是通过IIS将SQL Server 2008表格公开为XML / JSON。
我跟着few(1) videos(2)站起来一个WCF数据服务网络应用程序，当$元页面工作时，尝试查看实际数据会导致异常：
Operation could destabilize the runtime.
System.Security.VerificationException
我从这个VS2013 template开始使用.NET 4.5.1和Entity Framework 6.1.2 - 下面是更具体的软件包版本。
如果NuGet包导致VerificationException，我是否应该尝试删除所有NuGet包，并仅添加EntityFramework（以及依赖的任何内容）？
感谢任何想法，谢谢你们！

我安装了相同的软件包和更新，但我遇到了同样的错误。 我已经解决了这个问题：
1.按照该页面上的指南安装最新的Nuget包Microsoft.OData.EntityFrameworkProvider;
2.使用EntityFrameworkDataService替换DataService，例如在WcfDataService1.svc中：
public class WcfDataService1：EntityFrameworkDataService
但是我不知道它是否是最好的部分，因为有些ms教程没有说任何关于EntityFrameworkDataService的信息

我经历了一个痛苦的过程，用[DataServiceKey（＆＃34; ID＆＃34;）]和许多其他选项来装饰我的所有POCO。这根本不是必需的。只需从EntityFrameworkDataService而不是DataService继承您的服务。我知道Visual Studio模板将其添加为DataService＆lt;＆gt;。所以请执行以下操作，它将解决问题：
public class QueryServices : EntityFrameworkDataService<MathContext>
