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?
当前回答
我也有同样的问题，原因是标记“覆盖应用程序根URL”是在属性-> Web下设置的 在我删除标志后，IIS Express使用定义的端口正常启动。
其他回答
我也有同样的问题。我已经删除了C:/users/ path下的很多文件夹，以释放机器上的一些空间。在那之后，我开始得到这个错误。
我只是重新启动了我的机器，一切都很好。
我有同样的问题，在我的情况下，我只是清理，然后重建我的解决方案，它为我工作
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.
VS2015
编辑. csprojr .user文件
插入以下xml标记(如果已经存在，请不要重复)
<UseIIS>True</UseIIS>
<AutoAssignPort>True</AutoAssignPort>
<DevelopmentServerPort>2870</DevelopmentServerPort>
<DevelopmentServerVPath>/</DevelopmentServerVPath>
<IISUrl>http://localhost:2859</IISUrl>
<OverrideIISAppRootUrl>True</OverrideIISAppRootUrl>
<IISAppRootUrl>http://localhost:2859</IISAppRootUrl>
<NTLMAuthentication>False</NTLMAuthentication>
<UseCustomServer>False</UseCustomServer>
<CustomServerUrl>http://localhost/app</CustomServerUrl>
在XML节点中插入以上标签:
<ProjectExtensions><VisualStudio><FlavorProperties GUID="{349c5851-65df-11da-9384-00065b846f21}"><WebProjectProperties>
@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。
