visual studio 2012 - SmartStore.net installation dramas -

i'm having issue running new project...

it's smartstore.net version 2.x source downloaded , unzipped local dev machine (win 8.1 running iis 8.5)

create new website in iis pointing "smartstorenet-2.x\src\presentation\smartstore.web"

setup hosts file etc , set permissions on appdata, content, media, plugins

configured vs21012 web proj use iis website created previously.

build sln, good.

run sln ctrl+f5 , recieve "503 service unavailable" browser app pool has shut down many errors. errors?

if run without using iis , use inbuilt webserver in vs runs .less fails , there's no css. there .less plugin i'm missing?

any ideas appreciated

the minimum ide requirement smartstore.net visual studio 2013. should better try again vs 2015 community edition.
