System.Web.HttpcontextBase Orchard 1.8 中的问题（可能是由于 Visual studio 2015）
System.Web.HttpcontextBase problems in Orchard 1.8 (possibly due to Visual studio 2015)
我是 运行 Orchard 1.8 上的一个网站。
我尝试了 Visual Studio 2015 RC 并使用这个版本构建了我的 Orchard 项目。从那时起，我的错误日志中充斥着 Autofac 错误，表明 System.Web.HttpContextBase 无法解析（请参阅下面的堆栈跟踪）。
我恢复到 VS2013（我没有卸载 VS2015）但错误并没有消失。我不确定这是否是问题所在...
我部署解决方案的测试环境也开始出现同样的问题。
这是否与安装的.NET 版本有关？ （4.6 本地，4.5.2 远程）
此外，这似乎会导致堆栈溢出异常，这是目前的一个大问题。非常感谢任何线索！

在 1.9 的 this 提交中已修复，我能够挑选出提交的某些部分并能够修复错误。
我在 Visual Studio 2015 年构建后 运行 命令 "feature enable Orchard.Packaging" 时出现此错误。
我回到 VS 2012，重新构建项目并 运行 再次使用相同的命令 "feature enable Orchard.Packaging"，它开始工作了。
我终于能够 运行 命令 "package create..."。模块和主题再次开始更新。
我是 运行 Orchard 1.8 上的一个网站。
我尝试了 Visual Studio 2015 RC 并使用这个版本构建了我的 Orchard 项目。从那时起，我的错误日志中充斥着 Autofac 错误，表明 System.Web.HttpContextBase 无法解析（请参阅下面的堆栈跟踪）。
我恢复到 VS2013（我没有卸载 VS2015）但错误并没有消失。我不确定这是否是问题所在...
我部署解决方案的测试环境也开始出现同样的问题。
这是否与安装的.NET 版本有关？ （4.6 本地，4.5.2 远程）
此外，这似乎会导致堆栈溢出异常，这是目前的一个大问题。非常感谢任何线索！
