在Visual Studio 2015中设置打字稿

Question

I am working on a project that utilizes AngularJS / Gulp and we are attempting to migrate to Angular.

Can someone inform me on how to properly allow the addition of .ts files in a project using VS 2015? Steps performed so far:

- Installed Microsoft.TypeScript.Compiler v2.9.1 (stable) via Nuget packet manager
- npm install @angular/core
- npm install @angular/upgrade 
- npm install @angular/platform-browser
- npm install @angular/platform-browser-dynamic

When I add a .ts file to my project I receive 2500 errors. Some of which are shown below:

Error Build:'(' expected. app\node_modules\@angular\core\src\application_init.d.ts  17  
Error Build:'=' expected. \app\node_modules\@angular\core\src\application_init.d.ts 18      
Error Build:';' expected. \app\node_modules\@angular\core\src\application_ref.d.ts  185

What am I missing when adding a typescript file to my project that it causes so many issues?

EDIT:

I included a tsconfig.json file (below) and my error # reduced to 127. Am I missing additional config options?

{
  "compilerOptions": {
    "experimentalDecorators": true,
    "allowJs": true,
    "noImplicitAny": true,
    "target": "es6",
    "lib": ["es2016", "dom"]
}

Solution: The problem was I had a global and local install of typescript. I needed to run "npm uninstall -g typescript" and "npm uninstall typescript". From there do a fresh global install "npm install -g typescript"
