ERR_CONNECTION_REFUSED - .Net Core 1.0.1

Question

更新：即使是新的.net核心Web应用程序也显示相同的错误。

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

我将.Net Core SDK从版本1.0.0-preview2-003121升级到上面提到的。现在，当我尝试运行应用程序时，我收到错误：ERR_CONNECTION_REFUSED

当我在互联网上搜索时，大部分内容都是改变端口号。我改变了它，它仍然无法正常工作。

任何想法如何解决这个问题？

project.json文件是：

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

在我的情况下，它会在运行时抛出一堆警告，警告＆＃34;元素＆＃39; xxx＆＃39;在命名空间＆＃39; http // schemas.microsoft.com / developer / msbuild / 2003＆＃39;有无效的子元素...

目前正在回滚到Microsoft.NETCore.App：1.1.0将会这样做。

转到MyWebApplication\.vs\config\applicationhost.config验证bindingInformation PORT 是Right click on your project > Debug > App URL

中的同一端口

Answer 3

同样的问题。在简单宠物项目中从Core 1.1.0升级到1.1.1 - 无法在IIS Express上运行\ debug。看起来Core 1.1.1版本不够稳定。

Answer 4

我发现当我们在dependencies <{1}} project.json下错过以下内容时会发生这种情况

"Microsoft.NETCore.App": {
      "version": "1.0.1",
      "type": "platform"
    }

注意如果版本错误（在上面提到的那样），那么我们也会看到相同的错误。
