Visual Studio 2015 Does Not Display Or Nest Generated TypeScript .js file

I am attempting to use Type Script in Visual Studio 2015.

Saving the .ts file generates the .js file, but the .js file is  hidden and not nested under the .ts file. With a large project this will quickly become a mess.

Please explain why the .js file is not nested and why it is not automatically visible in the project?

Thanks,
Mark
