Question

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，我得到一个例外：

无法激活该服务，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 AspNetCompatibilityRequirements属性为服务类型 RequirementsMode设置为“允许”或“必需”

这是我的web.config：

<compilation debug="true">
  <assemblies>
    <add assembly="System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
    <add assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
  </assemblies>
</compilation>

  <service behaviorConfiguration="ExecutionEngine.AccountsBehavior" name="WebService.Services.Accounts">
    <endpoint address="" binding="wsHttpBinding" contract="WebService.Services.IAccounts" bindingConfiguration="SafeServiceConf">
      <identity>
        <dns value="localhost"/>
      </identity>
    </endpoint>
    <endpoint address="mex" binding="mexHttpsBinding" contract="IMetadataExchange"/>
  </service>

<serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>

Answer 1

示例：

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

Answer 2

您是否尝试将以下属性添加到服务类？

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]

然后，您可以使用HttpContext访问Session，如下所示：

 HttpContext.Current.Session

WCF aspNetCompatibilityEnabled =“true”引发异常（无法加载）
