I'm trying to setup an instance of Sitecore 8.2 so I can see what it's going to take to upgrade my site from Sitecore 8.1 to it. I've heard that Sitecore 8.2 can run SOLR natively (without using IOC), but I can't find any documentation that tells me how to do it. All that I'm able to find are documents describing how to setup SOLR using IOC. Thanks for your help!
In 8.2; SOLR support comes out of the box. You can optionally add your preferred DI container, but are not required to do so.
The Sitecore Solr provider uses an IOC (Inversion of Control) container so that all the elements inside it can be swapped without re-compilation. The default Sitecore installation includes a default implementation of the Solr connector (SolrNet.dll). If you need to use another IOC, download the Solr support package for your version of Sitecore from dev.sitecore.net (in the Additional tools section).
