我有一个ASP。NET MVC 4解决方案。当我尝试使用Visual Studio 2012打开它时，我得到以下错误:
Microsoft Visual Studio 为ASP配置Web https://localhost:。NET 4.5失败。你必须 手动配置此站点的ASP。NET 4.5才能使站点 正确地运行。无法在https://localhost:44300/上找到服务器 本地机器。确保已配置本地IIS服务器 支持安全通信。
尽管解打开了。此外，当我试图从调试菜单运行它时，我得到以下错误:
无法启动IIS Express Web服务器。 指定的起始URL无效。https://localhost:44300/
我无法调试代码。如何摆脱这些错误和调试/运行网站从VS 2012?

我在我的机器上为虚拟机设置了Internet连接共享。我把它关掉了，我就可以在Visual Studio 2015中调试了。然而，为了在重启后持续调试，我需要将Internet连接共享服务设置为手动启动，即使我的Internet连接都没有启用Internet连接共享。

Before you try anything else, make sure you 1. restart visual studio (mostly for refreshing memory resident options from files) and 2. restart your system (mostly for invalid file locking). If your problem is such temporary or self-fixed those will do without changing anything. It worked for me with PC restart. Also if you work on a multi-user project make sure you have the latest workable version - someone else may had check in something invalid by mistake at e.g. the project file and you mess with your system for no reason. If those won't work, then you probably need to alter some setting(s) that are stuck, missing or need modification - there are plenty propositions on other answers.
@roblll说对了。但对于那些不想挖掘答案的人来说，这就是:
Close Visual Studio (might not be necessary, but it won't hurt). Navigate to your Documents folder. This is where my IISExpress configuration directory was. In the config folder, there is a file called the application host. Open that. Search for the name of your project. It should have been added in there by Visual Studio when it bombed in your previous attempts. Note that there's a binding for HTTP with the port you intend to use for https. //Change this: <binding protocol="http" bindingInformation="*:44300:localhost" /> //to this: <binding protocol="https" bindingInformation="*:44300:localhost" />
请记住，Visual Studio可能提供了与您期望的不同的端口。只需确保绑定中的端口对应于项目属性的Web选项卡中的端口。

重启电脑是我唯一能做的事。经典101 IT:)
当我查看IIS Express注册表项时，我的问题最终解决了:
HKEY_CURRENT_USER\Software\Microsoft\IISExpress
我有一个CustomUserHome的入口指向我的网站，这是造成严重破坏。
对于dotnet核心中的2021解决方案，您可以通过在解决方案资源管理器中右键单击项目，并选择“编辑项目文件”来修复此错误。
在底部的Debug选项卡上，您可以直接配置所需的端口以及是否使用SSL。
这里的更改需要用Control+S保存。完成此操作后，您可以启动项目并确认它解决了您的问题，无需删除IISFolders或此处建议的任何其他内容。
