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?

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.

关闭Visual Studio的所有实例。 打开任务管理器。 结束所有活动的IIS进程。 重新启动Visual Studio。

我的问题被解决了:

在控制面板(程序和功能)中,我发现所有与IIS相关的功能都未选中。我最终检查了所有这些并重新启动了我的系统。 然后我以管理员的身份开始了我的VS 2013,仅此而已 那时工作得很好。

对我来说唯一有效的解决方案是创建另一个测试项目。然后按照下面的步骤:

Right click the project and go to Properties -> Web Under the project URL in the Use Local IIS Web Server section, copy the project URL(http:// localhost:59002/) - this is from the test project. Navigate to the project which is giving this error. Right click the project and go to Properties -> Web. Paste the project URL in the Use Local IIS Web Server section (URL copied from the test project). Close the test project and save. Delete the test project and run the project that gave the error. Works after that...

也许不是最好的方法,但这是我能让它工作的唯一方法。我收到这个错误消息后,我重新加载我的笔记本电脑(硬盘崩溃),并从他们所在的服务器上获得了我所有的项目。

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"
