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?

在我的情况下，我的applicationhost。配置文件以某种方式缺少以下两行代码
<add name="rules-64-ISAPI-2.0" path="*.rules" verb="*" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework64\v2.0.50727\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv2.0,bitness64" />
<add name="xoml-64-ISAPI-2.0" path="*.xoml" verb="*" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework64\v2.0.50727\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv2.0,bitness64" />

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.
我们的网站也遇到了同样的问题。我们能够在Visual Studio中解决这些问题。我们使用的是2012终极版。
我们看到的潜在问题是，由于某种原因，在启用SSL后，VS为标准url和安全url分配了相同的端口。当我们从TFS中提取代码时，这个问题似乎出现了。
为了补救，我们采取了以下步骤:
Right click the project and go to Properties -> Web Under the project URL in the Use Local IIS Web Server section, remove the "s" from the URL and Save. (EG. go from https://:44301 to http://:44301. This will allow the next step to work) In Solution Explorer, select the Project and in the Properties window (press F4 if not displayed) change SSL Enabled to False then back to True. It will generate a new port that is different from the standard URL (In my case, I have 44301 as my SSL and 44305 as my standard) Navigate back to Properties -> Web and add the "s" back to the project URL. F5 and ride!
确保未选中覆盖应用程序根URL的复选框。
我将提出一个解决这个问题的方法:
1.使用以下控制台命令删除\Documents\IISExpress文件夹:rmdir /s /q "%userprofile%\Documents\IISExpress"
Delete the applicationhost.config file which is placed within the .vs\Config\ folder in your Visual Studio project root folder. Change the project’s website random URL: within Visual Studio, right-click to the project node in Solution Explorer, then select Properties; navigate through the Web panel, then change the number in the Project Url textbox value. Add the _CSRUN_DISABLE_WORKAROUNDS Environment System variable with the value of 1 as shown in the following screenshot (thanks to Juan M. Elosegui for reporting this on this SO thread and for the image):
好运！
其他的解决方法对我都不起作用。我禁用了“编辑-继续”功能，一切正常:)
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。
