c# - ERR_CONNECTION_REFUSED - .Net Core 1.0.1

Question

更新:即使是新的 .net 核心网络应用程序也显示相同的错误。

我正在使用 .Net Core 版本 1.0.0-preview2-003131。

我将 .Net Core SDK 从版本 1.0.0-preview2-003121 升级到上述版本。现在，当我尝试运行该应用程序时，出现错误:ERR_CONNECTION_REFUSED

当我在互联网上搜索时，大部分内容都是更改端口号。我更改了它，但它仍然不起作用。

有什么办法解决这个问题吗？

当我将我的应用程序更新到 Microsoft.NETCore.App: 1.1.1 时，我个人偶然发现了类似的问题

在我的例子中，它在运行时抛出一堆警告，警告“命名空间‘http//schemas.microsoft.com/developer/msbuild/2003’中的元素‘xxx’具有无效的子元素...

暂时回滚到 Microsoft.NETCore.App:1.1.0 即可。
