尝试确定在干净安装的Windows 10 + vs2015上托管应用程序的DNX进程的进程ID时发生错误

我有一个干净安装的Windows 10,以及一个干净安装的VS 2015 Update 1与RC1 ASP.NET工具.当我开始一个没有任何身份验证的新的ASP.NET MVC项目!和Hit F5时,我得到"尝试确定托管您的应用程序的DNX进程的进程ID时出错"错误.

我没有VS或ASP.NET的任何旧版本.一切都是最新的干净安装.我浏览了这个文档:http://docs.asp.net/en/latest/getting-started/installing-on-windows.html

我找到了这个主题,但这不是一个重复的问题,因为我没有升级任何东西,这个问题就出现在干净安装的Windows 10 + VS 2015 Update 1系统上.我有一个Windows 8.1和VS2013 + VS2015系统,一切正常.我认为在Windows 10上设置ASP.NET 5环境必须有一些额外的步骤.

在这里,我的project.json文件:
