Hi,

Create a new dub package with dub init and afterwards change the 
filename app.d to lib.d. Use as file content

``` d
import core.sys.windows.dll;
mixin SimpleDllMain

extern(C) void sample() nothrow
{
}
```

In dub.json set targetType to "dynamicLibrary".

Build with `dub build`

(Written from my mobile, with the knowledge, as far as I 
remember).

Kind regards
Andre
