Encountering TypeScript 2 Compilation Issue with Angular 2 in VisualStudio 2015 Update 3

Encountering an error during the compilation of a TypeScript project that was functioning perfectly prior to upgrading to V2. I have transitioned from Typings to @Types and am only importing @Types/node in the project.

Severity Code Description Project File Line Suppression State Error TS2309 Build:An export assignment cannot be used in a module with other exported elements. XXXXXXXXX C:\Projects\XXX\XXXXXXXXX \node_modules\@types\node\index.d.ts 3626

Here is the TsConfig configuration -

{
  "compilerOptions": {
    "moduleResolution": "node",
    "target": "es5",
    "sourceMap": true,
    "experimentalDecorators": true,
    "emitDecoratorMetadata": true,
    "skipDefaultLibCheck": true,
    "outDir": "../wwwroot/app",
    "lib": [ "es6", "dom" ],
    "types": [ "node" ]
  },
  "exclude": [ "bin", "node_modules" ],
}

I have come across someone else facing the same error without a solution. It seems like a minor setup or config issue, as the project compiled perfectly fine before the update. Any assistance would be highly appreciated.

Special thanks to the TS developers on GitHub for assisting us in conducting a search for -

declare module "assert" { .. }

This declaration should only be present once in your project. Turns out, we had an outdated file lingering in our wwwroot directory which, once removed, successfully fixed the issue.
