WCF aspNetCompatibilityEnabled="true" 引发异常（加载失败）答案

【问题描述】：

我需要在我的 WCF 服务中启用会话。所以我必须：

<serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>

当我这样做时，我得到一个异常：

该服务无法激活，因为它不支持 ASP.NET 兼容性。为此应用程序启用了 ASP.NET 兼容性。在 web.config 中关闭 ASP.NET 兼容模式或添加服务类型的 AspNetCompatibilityRequirements 属性 RequirementsMode 设置为“允许”或“必需”

这是我的 web.config：

<serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>

【问题讨论】：

标签： c# asp.net wcf session

【解决方案1】：

例子：

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

【讨论】：

谢谢。你能告诉我如何启用会话和访问它吗？

【解决方案2】：

您是否尝试将以下属性添加到您的服务类？

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]

然后您可以像这样使用 HttpContext 访问 Session：

 HttpContext.Current.Session

【讨论】：

如果您发布代码、XML 或数据示例，请在文本编辑器中突出显示这些行，然后单击编辑器上的“代码示例”按钮 ({ })工具栏以很好地格式化和语法突出显示它！
谢谢！这是我在 stackoverflow 上的第一篇文章 :) 下次我会做的！
