找不到方法：'System.Collections.ObjectModel.Collection`1

嗨，当我发布我的WebService时，我得到了这个关注的错误，
找不到System.Net.Http.Formatting.MediaTypeFormatter.get_SupportedMediaTypes()'. 方法：'System.Collections.ObjectModel.Collection`1
但当我在VS调试模式下使用它时，就不会发生这种情况。我已经在谷歌上搜索过了，并尝试在webconfig上使用程序集引用，但它不起任何作用？
这是我当前的webconfig文件
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</configSections>
<system.web>
<customErrors mode="Off"/>
</system.web>
<system.webServer>
<httpErrors errorMode="Detailed" />
</system.webServer>
<system.web>
<httpRuntime executionTimeout="3000000" maxRequestLength="1048576" />
<compilation debug="true" targetFramework="4.0">

</dependentAssembly>
</runtime>
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="basicHttp" allowCookies="true" maxReceivedMessageSize="20000000" maxBufferSize="20000000" maxBufferPoolSize="20000000">

</binding>
</basicHttpBinding>
</bindings>
</system.serviceModel>
</configuration>这是抛出错误的类
class WebApiConfig
{
public static void Register(HttpConfiguration configuration)
{
configuration.Formatters.JsonFormatter.SupportedMediaTypes.Add(new MediaTypeHeaderValue("text/html"));
configuration.Routes.MapHttpRoute("API Default", "api/{controller}/{id}",
new { id = RouteParameter.Optional });
}
