Currently I'm using dmd but the release binaries I'll be usind 
ldc. Is this how I can enable visual styles on dmd? and how is 
this done on ldc?

I haven't played with the pragma yet but I've done it before both 
with the file.exe.manifest XML file sitting alongside it and with 
the resource compiler before (you can use the same resource 
compilers for D as you use for C btw)

I have done that before with the XML manifest file but now I'd to do it without that external dependence, now I'm trying with the linker, if possible. It seems SetWindowTheme(hwnd, L"Explorer", NULL) do the same, I'm researching into that

if someone happens to be looking to do that in the future: I 
didn't find a way to do this with a linker but managed to find a 
way to do this with code only. The code goes like this:

// source: https://stackoverflow.com/a/10444161/800123
#include <windows.h>

// NOTE: It is recommended that you delay-load ComCtl32.dll 
(/DelayLoad:ComCtl32.dll)
// and that you ensure this code runs before GUI components are 
loaded.
// Otherwise, you may get weird issues, like black backgrounds in 
icons in image lists.
ULONG_PTR EnableVisualStyles(VOID)
{
     TCHAR dir[MAX_PATH];
     ULONG_PTR ulpActivationCookie = FALSE;
     ACTCTX actCtx =
     {
         sizeof(actCtx),
         ACTCTX_FLAG_RESOURCE_NAME_VALID
             | ACTCTX_FLAG_SET_PROCESS_DEFAULT
             | ACTCTX_FLAG_ASSEMBLY_DIRECTORY_VALID,
         TEXT("shell32.dll"), 0, 0, dir, (LPCTSTR)124
     };
     UINT cch = GetSystemDirectory(dir, sizeof(dir) / 
sizeof(*dir));
     if (cch >= sizeof(dir) / sizeof(*dir)) { return FALSE; 
/*shouldn't happen*/ }
     dir[cch] = TEXT('\0');
     ActivateActCtx(CreateActCtx(&actCtx), &ulpActivationCookie);
     return ulpActivationCookie;
}

it's C as code but can be translated to D easy.
