Why does VS.NET 2013 create a dll file in the bin directory when I build my HTML5 Typescript project?
I think it's because Typescript is not a mature product yet. They are leveraging the existing class library to help us partition our modules, but as a result, you still get an empty DLL in the bin directory. This DLL is pointless and you can safely ignore it.
If you want to kill this auto-generated DLL, then remove that specific project from the build configuration.
