C# 从MVC 4应用程序访问数据库时出错

我在Visual Studio 2013中创建了一个MVC4 web应用程序。我的应用程序使用EF5访问SQLServer2005数据库。在我本地的Windows7机器上，它工作正常。在本地，.NET的版本是4.0.30319.18408。当我将它部署到我的服务器（Windows server 2003，IIS 6）时，该应用程序可以工作，除非我浏览到访问数据库的页面。.NET的服务器版本为4.0.30319.1022

当应用程序尝试访问数据库时，我收到以下错误：

System.InvalidOperationException: Failed to set Database.DefaultConnectionFactory to an instance of the 'System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework' type as specified in the application configuration. See inner exception for details. ---> System.MissingMethodException: Constructor on type 'System.Data.Entity.Infrastructure.SqlConnectionFactory' not found. at System.RuntimeType.CreateInstanceImpl(BindingFlags bindingAttr, Binder binder, Object[] args, CultureInfo culture, Object[] activationAttributes) at System.Activator.CreateInstance(Type type, BindingFlags bindingAttr, Binder binder, Object[] args, CultureInfo culture, Object[] activationAttributes) at System.Data.Entity.Internal.AppConfig.<.ctor>b__1() --- End of inner exception stack trace --- Server stack trace: at System.Data.Entity.Internal.AppConfig.<.ctor>b__1() at System.Lazy`1.CreateValue() Exception rethrown at [0]: at System.Lazy`1.get_Value() at System.Data.Entity.Internal.LazyInternalConnection.Initialize() at System.Data.Entity.Internal.LazyInternalConnection.get_ProviderName() at System.Data.Entity.Internal.LazyInternalContext.InitializeContext() at System.Data.Entity.Internal.InternalContext.GetEntitySetAndBaseTypeForType(Type entityType) at System.Data.Entity.Internal.Linq.InternalSet`1.Initialize() at System.Data.Entity.Internal.Linq.InternalSet`1.get_InternalContext() at System.Data.Entity.Infrastructure.DbQuery`1.System.Linq.IQueryable.get_Provider() at System.Linq.Queryable.OrderBy[TSource,TKey](IQueryable`1 source, Expression`1 keySelector) at DPO.Controllers.CustomersController.Index() in c:\Users\halejd\Documents\Visual Studio 2013\Projects\DPO\DPO\Controllers\CustomersController.cs:line 98 at lambda_method(Closure , ControllerBase , Object[] ) at System.Web.Mvc.ActionMethodDispatcher.Execute(ControllerBase controller, Object[] parameters) at System.Web.Mvc.ReflectedActionDescriptor.Execute(ControllerContext controllerContext, IDictionary`2 parameters) at System.Web.Mvc.ControllerActionInvoker.InvokeActionMethod(ControllerContext controllerContext, ActionDescriptor actionDescriptor, IDictionary`2 parameters) at System.Web.Mvc.Async.AsyncControllerActionInvoker.<>c__DisplayClass42.<BeginInvokeSynchronousActionMethod>b__41() at System.Web.Mvc.Async.AsyncResultWrapper.<>c__DisplayClass8`1.<BeginSynchronous>b__7(IAsyncResult _) at System.Web.Mvc.Async.AsyncResultWrapper.WrappedAsyncResult`1.End() at System.Web.Mvc.Async.AsyncControllerActionInvoker.EndInvokeActionMethod(IAsyncResult asyncResult) at System.Web.Mvc.Async.AsyncControllerActionInvoker.<>c__DisplayClass37.<>c__DisplayClass39.<BeginInvokeActionMethodWithFilters>b__33() at System.Web.Mvc.Async.AsyncControllerActionInvoker.<>c__DisplayClass4f.<InvokeActionMethodFilterAsynchronously>b__49() at System.Web.Mvc.Async.AsyncControllerActionInvoker.<>c__DisplayClass37.<BeginInvokeActionMethodWithFilters>b__36(IAsyncResult asyncResult) at System.Web.Mvc.Async.AsyncResultWrapper.WrappedAsyncResult`1.End() at System.Web.Mvc.Async.AsyncControllerActionInvoker.EndInvokeActionMethodWithFilters(IAsyncResult asyncResult) at System.Web.Mvc.Async.AsyncControllerActionInvoker.<>c__DisplayClass25.<>c__DisplayClass2a.<BeginInvokeAction>b__20() at System.Web.Mvc.Async.AsyncControllerActionInvoker.<>c__DisplayClass25.<BeginInvokeAction>b__22(IAsyncResult asyncResult);

有什么想法吗？

在web.config文件中添加连接字符串。它不在那里。它在顶部附近。我尝试更改连接字符串的格式以匹配您的格式，但收到相同的错误。
