I am using Visual Studio 2015 Express Web and had the same problem. I searched a lot for solutions and none of these worked:

我正在使用 Visual Studio 2015 Express Web 并且遇到了同样的问题。我搜索了很多解决方案，但这些都没有奏效：

• Reinstall Nuget for Visual Studio 2015
• Replace Nuget for Visual Studio 2015 with the former Nuget
• Run Visual Studio as Administrator
• Modify/Delete IISExpress applicationhost.config file
• Reinstall IISExpress

• 为 Visual Studio 2015 重新安装 Nuget
• 用以前的 Nuget 替换 Visual Studio 2015 的 Nuget
• 以管理员身份运行 Visual Studio
• 修改/删除 IISExpress applicationhost.config 文件
• 重新安装 IISExpress

The only thing that solved it was a Repair-installof Visual Studio:

解决它的唯一方法是修复安装Visual Studio：

• Press Windows+ R
• Enter appwiz.cpland press Enter
• Right-click the entry "Microsoft Visual Studio Express 2015 for Web" and click "Repair"
• Be patient...

• 按Windows+R
• 输入appwiz.cpl并按下Enter
• 右键单击“Microsoft Visual Studio Express 2015 for Web”条目，然后单击“修复”
• 要有耐心...

Note:This is going to reinstall all packages that you have uninstalled, because you weren't needing them (eg. Microsoft SQL Server Native Client).

注意：这将重新安装您已卸载的所有软件包，因为您不需要它们（例如 Microsoft SQL Server Native Client）。

I had the same error using VS community 2017 (and previous), when trying to open a .cs file, or trying to open project properties. All that on a fresh VS install on a fresh Windows 10 install...

在尝试打开 .cs 文件或尝试打开项目属性时，我在使用 VS 社区 2017（及之前）时遇到了同样的错误。所有这些都在全新的 Windows 10 安装上的全新 VS 安装上...

I found 2 solutions:

我找到了2个解决方案：

Start VS as admin (which is not a good choice, and may prevent debugging drag&drop into your app).

以管理员身份启动 VS（这不是一个好的选择，并且可能会阻止调试拖放到您的应用程序中）。

or better:

或更好：

Change security settings of your %temp% folder to "everyone - full control". :)

将 %temp% 文件夹的安全设置更改为“everyone - full control”。:)

I encountered a similar problem when creating a .NET core project in VS 2015, and it's resolved by repairing .NET Core. The possible reason is, my .NET core was installed associated with VS community version, but later I uninstall VS community and reinstall professional version, but .NET Core was not uninstalled with community version uninstall. After repairing .NET core from control panel, it works now.

我在VS 2015中创建.NET Core项目时遇到了类似的问题，通过修复.NET Core解决了。可能的原因是，我的.NET Core是和VS社区版关联安装的，后来我卸载了VS社区，重新安装了专业版，但是没有卸载社区版的.NET Core。从控制面板修复 .NET core 后，它现在可以工作了。

Do you have the relevent components installed along with Visual Studio?

您是否与 Visual Studio 一起安装了相关组件？

I was getting this error when trying to add a new Axure Mobile Services project. Knowing how long repairing Visual Studio takes, I hoped to avoid that.

尝试添加新的 Axure 移动服务项目时出现此错误。知道修复 Visual Studio 需要多长时间，我希望避免这种情况。

What fixed it for me was opening up Programs and Features, and selecting "Modify" Visual Studio rather than "Repair".

对我来说修复它的是打开程序和功能，然后选择“修改”Visual Studio 而不是“修复”。

I'm not sure if there was an error in a previous installation that I didn't notice, but Web Tools wasn't selected in the installed components. After selecting that, installing, and restarting my computer, I no longer got the error when trying to add a new project.

我不确定以前的安装中是否存在我没​​有注意到的错误，但是在安装的组件中没有选择 Web Tools。选择它，安装并重新启动计算机后，尝试添加新项目时不再出现错误。
