c# - WCF aspNetCompatibilityEnabled ="true"引发异常(加载失败)

Question

我需要在我的 WCF 服务中启用 session 。所以我必须:

<serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>

当我这样做时，我得到一个异常:

The service cannot be activated because it does not support ASP.NET compatibility. ASP.NET compatibility is enabled for this application. Turn off ASP.NET compatibility mode in the web.config or add the AspNetCompatibilityRequirements attribute to the service type with RequirementsMode setting as 'Allowed' or 'Required'

这是我的 web.config:

<compilation debug="true">
  <assemblies>
    <add assembly="System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>

例子:

namespace WcfService1
{
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]
    public class Service1 : IService1
    {
