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?

我也有同样的问题，感谢@Jacob提供的信息。
原因是-在配置文件applicationhost中错误的项目条目
C:\Users\(yourusername)\Documents\IISExpress\config
关闭所有Visual Studio解决方案。 重命名IISExpress文件夹为一些IISExpress- copy(而不是删除你可以有一个副本) 现在再次打开VS并构建/调试项目，现在你会看到IISExpress文件夹再次为你创建了正确的配置。

分享给未来的读者。手动创建一个虚拟目录对我来说很有用。
在解决方案资源管理器中选择项目 按Alt + Enter 转到网页部分 单击“创建虚拟目录”
确保以管理员身份运行VS !这将解决一切问题。比我晚。
我也有同样的问题。 原因是IIS配置文件不好。
尝试删除自动创建的IISExpress文件夹，该文件夹通常位于%userprofile%/Documents，例如C:\Users\[you]\Documents\IISExpress。
别担心，一旦你再次运行你的解决方案，VS应该再次创建它——这次是正确的。
EDIT:删除文件夹的命令行:
rmdir /s /q "%userprofile%\Documents\IISExpress"
@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。

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.
