Steps to Reproduce:
Create a Typescript project
Write the class declaration, e.g.

export class AuthService {
    constructor(private http: Http) {}
}

Experimental support for decorators is a feature that is subject to change in a future release. Set the ‘experimentalDecorators’ option to remove this warning.

I have the following in my > File/preference/user settings in vscode

{
  "typescript.tsdk": "node_modules/typescript/lib"
}

Also, in tsconfig.json file in the root directory of my project I have include the following options.

{
    "compilerOptions": {
        "experimentalDecorators": true,
        "allowJs": true
    }
}

Does this issue occur when all extensions are disabled?: Yes/No
Yes

In the TS file, run the TypeScript: Go to project configuration vscode command. Does this open the correct tsconfig file?

In VSCode, Go to File => Preferences => Settings (or Control+comma) and it will open the User Settings file. Add "javascript.implicitProjectConfig.experimentalDecorators": true to the file and it should fix it. It did for me.

Thanks @gondomar - that solved the issue for now..

EDIT: This was basically the issue caused by an extension called "Javascript and TypeScript Intellisense"..after disabling, the issue is resolved!

I have this issue in a javascript project where I am using es6 decorators like @inject.                        

example code:

@inject(UserService)
@inject(ApplicationService)
class PushService {
 constructor(userService, applicationService) {
 this.userService = userService;
 this.applicationService = applicationService;
 }
}

my jsconfig.json file is:

    "compilerOptions": {
        "experimentalDecorators": true
    }
}

One of the file that gives me this "decorator" warning/error is in the path:
./server/service/src/com/tray/communication/push/PushService.js                        

I have already tried including and excluding the folders that I wouldn't need etc.
I tried javascript.implicitProjectConfig.experimentalDecorators: true option, but that didn't work either.

Basically, I have wasted my 3 hours trying to figure this thing out..
I don't have typescript installed locally in my project (since I am not using it at all).

Any help would be appreciated.
Thanks

重现步骤：
创建一个Typescript项目
编写类声明，例如                        

export class AuthService {
    constructor(private http: Http) {}
}

对装饰器的实验支持是一项功能，将来的版本中可能会对其进行更改。设置“ experimentalDecorators”选项以删除此警告。                        

我在> vscode中的>文件/首选项/用户设置中有以下内容                        

{
  "typescript.tsdk": "node_modules/typescript/lib"
}

另外，在我项目的根目录下的tsconfig.json文件中，我包括以下选项。                        

{
    "compilerOptions": {
        "experimentalDecorators": true,
        "allowJs": true
    }
}

禁用所有扩展名时会发生此问题吗？：是/否
是                        

在TS文件中，运行TypeScript: Go to project configurationvscode命令。这会打开正确的tsconfig文件吗？                        

在VSCode中，转到File => Preferences => Settings（或Control +逗号），它将打开User Settings文件。在文件中添加“ javascript.implicitProjectConfig.experimentalDecorators”：true，它应该对其进行修复。它对我有用。                        

感谢@gondomar- 目前已解决了该问题。                        

编辑：这基本上是由名为“ Javascript and TypeScript Intellisense”的扩展名引起的问题。禁用后，此问题已解决！                        

我在使用es6装饰器的javascript项目中遇到了这个问题@inject。                        

示例代码：                        

@inject(UserService)
@inject(ApplicationService)
class PushService {
 constructor(userService, applicationService) {
 this.userService = userService;
 this.applicationService = applicationService;
 }
}

我的jsconfig.json文件是：                        

    "compilerOptions": {
        "experimentalDecorators": true
    }
}

给出此“装饰器”警告/错误的文件之一在路径中：
./server/service/src/com/tray/communication/push/PushService.js                        

我已经尝试过包括和排除不需要的文件夹等。
我尝试了javascript.implicitProjectConfig.experimentalDecorators: true选项，但是那也不起作用。                        

基本上，我已经花了3个小时试图弄清楚这个问题。.
我的项目中没有本地安装打字稿（因为我根本没有使用过）。                        

任何帮助，将不胜感激。
谢谢
