experimental support for decorators visual studio 2017

Question

I have created a .Net Core project with AngularJS in Visual Studio 2017 however when I am trying to create a service, I am getting an error as

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 checked several links such as editing tsconfig.json following links such as link1 and link2

Now my tsconfig.json looks like below

    {   "compileOnSave": false,   "compilerOptions": {     "outDir": "./dist/out-tsc",     "sourceMap": true,     "declaration": false,     "moduleResolution": "node",     "experimentalDecorators": true,     "allowJs": true,     "noEmit": true,     "target": "es5",     "typeRoots": [       "node_modules/@types"     ],     "lib": [       "es2017",       "dom"     ]   },   "include": [     "app/**/*"   ],   "files": [], //add a "files" array (in my case empty)   "exclude": [     "node_modules"   ],   "typeAcquisition": {     "enable": true // helps fuel better js intellisense   } } 

But I still see the error and I am clueless now.

Answer 1

add

<PropertyGroup> <TypeScriptExperimentalDecorators>true</TypeScriptExperimentalDecorators></PropertyGroup> 

in .csproj file of your project as it will be given precedence over tsconfig.json file and the restart visual studio and the error is no longer there.
