Visual Studio Javascript格式忽略我的设置

Question

[没有明显的原因，星期一，我的VS2017开始在this SO post中突出显示错误，并且所有JS Intellisense和自动格式化都消失了。

通过关闭Enable the new JavaScript language service设法解决了这个问题，但是现在自动格式化功能忽略了我的设置；内部样式在设置了功能之后的换行符上设置了大括号，但现在Ctrl-E-D重新格式化可将所有大括号移动到与函数定义相同的行。

我该如何解决？

编辑：我发现此旧线程存在相同的问题，但可惜没有针对新语言服务的修复：https://developercommunity.visualstudio.com/content/problem/138728/if-statements-still-place-a-opening-brace-on-the-s.html

令人烦恼的是，它已经工作了好几个月，直到昨天才停止，没有任何设置更改。

编辑以添加Intellisense错误：

The JavaScript and TypeScript language service has been disabled due to an error. You may see reduced IntelliSense support for your project. Please try reloading your solution to reenable the language service.

Answer 1

禁用新语言服务。

1。禁用JavaScript Language Service后，使用Developer command prompt中的以下命令设置选项：

CD %VSINSTALLDIR%

vsregedit set . HKCU "ApplicationPrivateSettings\TextEditor\JavaScript\Specific" "PlaceOpenBraceOnNewLineForControlBlocks" string "0*System.Int32*1"

请参见this。

启用新语言服务。

2。尝试创建一个新项目（也许您在node.js项目中？），以检查是否仍然存在类似问题，如果该问题消失了，则可能是您的项目现在包含太多JS文件的原因。请参见此处的limitation。

如果问题仍然存在于新项目中，请修复VS或将VS2017更新到最新的15.9.16，以检查是否有帮助。我想您的环境中有些东西坏了。

此外，在关闭VS .vs并重新启动VS之后，尝试删除解决方案目录中隐藏的clean the VS cache文件夹。
