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!

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> 

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。

我也有同样的问题。请遵循以下步骤:

1-在Documents\IISExpress\config中打开applicationhost文件,如果不存在,则添加以下代码

            <site name="solutionname" id="2">
                <application path="/" applicationPool="solutionname">
                    <virtualDirectory path="/" physicalPath="physicaladdressofproject" />
                </application>
                <bindings>
                    <binding protocol="http" bindingInformation="*:xxxx:localhost" />
                </bindings>
            </site>

2-然后转到项目的根文件,删除使用不同版本的Visual Stdio对项目进行的所有更新

3-下一步进入[root]。vsconfig,删除applicationhost 它将自动创建

4 .运行项目

这对我很管用。

我在VS2012中运行我的解决方案时遇到了类似的问题:

无法启动IIS Express Web服务器。 指定的起始URL无效。https://localhost:44301/

我将不正确的项目选择为启动项目。我使云项目启动(右键单击项目->设置为启动项目),一切开始工作正常。

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.
