In short - as much as I like D, I'd avoid using it in this 
scenario if you want to make fast progress and don't want to 
spent a lot of time on it.

1) Creating a windows service - shouldn't be a problem. There's (never tried it, but 
should get you started)

2) Hosting vibe-d application in IIS - probably only by means of 
reverse proxy - see ie as .Net 
Core is hosted the same way there

3) MS SQL - real problems starts here..

I don't know of any D project to provide MS SQL connectivity for 

If I'm not mistaken D provides only basic ODBC bindings here:
So you would need to work with ODBC drivers with it.

This could be a good starting point:

But there'll probably be a problem with async access needed for 
vibe (or you'd block fibers).
See for a 
project that works with vibe by using async methods of underlying 
libpq and socket events handled by vibe-d - you'll need something 
like that too (and I don't know if ODBC driver can support 
something like that - seems it should be possible:

As this is all pretty lowlevel stuff, you'll end up writing some 
abstraction layer above.

Other option (probably better but even more time consuming) would 
be to implement MS SQL communication protocol natively for vibe-d 
(similarly to mysql-native).


Rust has it this way too:

So it's all doable, but there isn't existing solution you could 
use right away and profit.
