无法在IISExpress中启动ASP.NET Core RC2 Web应用程序

我在VS2015中创建了一个新的“ ASP.NET Core Web应用程序（.NET Core）”项目。它的构建没有任何问题，因此我想对其进行测试。但是，在启动时，它因以下错误而阻塞并崩溃：

Exception thrown: 'System.AggregateException' in Microsoft.AspNetCore.Server.Kestrel.dll
The program '[11608] dotnet.exe' has exited with code -1073741819 (0xc0000005) 'Access violation'.
The program '[15048] iisexpress.exe' has exited with code 0 (0x0).

我没有看到其他记录。我尝试对其进行调试，结果发现它WebHostBuilder.Run()在Program类中的方法期间损坏。它是框架的一部分，所以我无法进一步了解。

请注意，通过dotnet run命令运行时程序运行正常。仅IISExpress不起作用。

我应该如何调试此问题？

project.json文件在下面。（它是由Visual Studio生成的，我没有做任何更改。）

更新：我为Core RTM版本创建了一个新项目，这次它可以工作了。
