Turning off “Language Service Disabled” error message in VS2017

Question

We are getting the following \"Error\" message in our MVC web application in Visual studio 2017 Enterprise.

The language service is disabled for proje

Answer 1

To solve this issue do the following:

• Create file in root directory of your project and call it tsconfig.json
• Add this:

{
  "compilerOptions": {
    "allowJs": true, 
    "noEmit": true, 
    "module": "system",
    "noImplicitAny": true,
    "removeComments": true,
    "preserveConstEnums": true,
    "sourceMap": true
  },
  "include": [
    "scripts"
  ],
  "exclude": [

  ],
  "typeAcquisition": {
    "enable": true 
  }
}

Please have a look at the below two links for tsconfig.json explanation, because you may still need to change it according to your setup. This is the only way that worked for me. I hope that will help.
