tsconfig.json: Build:No inputs were found in config file

I have an ASP.NET core project and I'm getting this error when I try to build it:

error TS18003: Build:No inputs were found in config file 'Z:/Projects/client/ZV/src/ZV/Scripts/tsconfig.json'. Specified 'include' paths were '["**/*"]' and 'exclude' paths were '["../wwwroot/app","node_modules/*"]'.
1>         The command exited with code 1.
1>       Done executing task "VsTsc" -- FAILED.

This is my tsconfig.json file:

{
  "compileOnSave": true,
  "compilerOptions": {
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "lib": [ "es5", "dom" ],
    "module": "commonjs",
    "moduleResolution": "node",
    "noEmitOnError": true,
    "noImplicitAny": false,
    "outDir": "../wwwroot/app/",
    "removeComments": false,
    "sourceMap": true,
    "target": "es6"
  },
  "exclude": [
    "../wwwroot/app",
    "node_modules/*"
  ]
}

Is this a bug or am I doing something wrong? I did recently upgrade Visual Studio 2015 to update 3. Has anyone encountered this before?

Add an empty typescript file to the typescript scripts folder (the location of your tsconfig file) to satisfy the typescript compiler.

You can also try to restart your code editor. That works well too.

This can occur because typescript server can't find any files described by the include array:

// tsconfig.json
{
  //...
  "include": [
    "./src/"
  ],
}

If you're using VSCode, you can restart your TS server within your editor super easily to prompt it to re-evaluate the file like this:

1. Navigate to any .ts or .tsx file

2. Open the command palette (CMD + SHIFT + P on mac)

3. Run the TypeScript: Restart TS server command:

   

I'm not using TypeScript in this project at all so it's quite frustrating having to deal with this. I fixed this by adding a tsconfig.json and an empty file.ts file to the project root. The tsconfig.json contains this:

{
  "compilerOptions": {

    "allowJs": false,
    "noEmit": true // Do not compile the JS (or TS) files in this project on build

  },
  "compileOnSave": false,
  "exclude": [ "src", "wwwroot" ],
  "include": [ "file.ts" ]
}
