问题描述
Hi All.
我将Windows 7 Enterprise和VS 2015 Enterprise与Update 3一起使用.VisualStudio出现问题.我先卸载然后重新安装了VS2015.重新安装后，我需要运行修复模式.最后我有能力运行VS.当我打开它时，我发现 缺少ASP.NET模板.在MSDN论坛中，我找到了帖子:
I'm using Windows 7 Enterprise and VS 2015 Enterprise with Update 3. I have problem with Visual Studio. I uninstall and then reinstalled VS 2015. After re-installation I need to run Repair mode. Finally I have ability to run VS. When I open it I found that ASP.NET templates was missed. In MSDN forum I found post:
https://social.msdn.microsoft.com/Forums/zh-CN/2b75f659-521e-4e08-b093-11d7bfb63ef1/missing-web-templates-for-c-in-visual-studio-2015?forum=netfxsetup

我提出了这样的建议:
I performed such suggestion:
请转到项目存储文件夹，例如C:\ Program Files(x86)\ Microsoft Visual Studio 14.0 \ Common7 \ IDE \ ProjectTemplates，然后检查是否为CSharp/Web文件夹.如果此文件夹及其子项存在，请打开管理CMD窗口并浏览
到C:\ Program Files(x86)\ Microsoft Visual Studio 14.0 \ Common7 \ IDE并运行以下命令:
devenv/resetuserdata
devenv/resetSettings
devenv/InstallVSTemplates
Please go to the project store folder like C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\ProjectTemplates and check if the CSharp/Web folder. if this folder and its subitems are existing, Please open an administrative CMD window and navigate
to C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE and run the following commands:
devenv /resetuserdata
devenv /resetSettings
devenv /InstallVSTemplates
现在，当我打开Visual Studio并单击新建项目时；我就像在闪烁该屏幕一样
Now when I open Visual Studio and click New Project I'm getting like blink that screen
然后出现错误信息:
如何解决问题?如果要解决问题最好卸载VS.如何使用Update 3完全卸载VS 2015 Enterprise?
How to fix the problem? If to solve the problem better to uninstall VS. How to uninstall VS 2015 Enterprise with Update 3 completely?
谢谢.

2. Visual Studio卸载程序工具: https://github.com/Microsoft/VisualStudioUninstaller/releases .此可执行文件旨在清除/烧录所有Preview/RC/RTM版本 Visual Studio 2013，Visual Studio 2015和Visual Studio vNext版本.应该使用它作为最后的手段来清理用户的系统，然后再重新构想计算机.

This executable is designed to cleanup/scorch all Preview/RC/RTM releases of Visual Studio 2013, Visual Studio 2015 and Visual Studio vNext. It should be used as a last resort to clean up the user's system before resorting to reimaging the machine.
在下一次安装之前，请确保您的操作系统已升级到Windows 7 SP1，Windows Update已更新到日期，暂时禁用所有防病毒软件并清理％temp％ 文件夹，使用带有更新3的VS Enterprise 2015的正常ISO文件进行安装，并以管理员身份运行安装程序.
