Once you’re up and running with Sitecore 9, you’re likely going to want to setup Sitecore Rocks.  Due to some security changes with Sitecore 9, Rocks will have a problem connecting to the instance.

Upon hitting the “Test” button in the Connection Manager, you’ll be greeted with the following:

If you go into the web.config and apply the following update (Do it in a transform, so it doesn’t make its way up to production), you should be good to go.

This should allow Rocks to connect to your instance.

Special thanks to Kern Nightingale on the forums for the insight into this!

This entry is part of my series "Nine on Nine" which is a "quick peek" at nine new things in Sitecore 9.  I've been messing a bit with the Technical Preview, and there's lots of exciting stuff to share.  Some of these might change a little in regards to General Availability, but hopefully not too much... These posts won't cover everything in depth, as I hope to do more detailed analysis in the coming months. Other Entries in Nine on Nine

There's more than just nine new things.  XConnect is a huge change to how data is collected.  Cloud-first support is another big thing.  Look to the official RSS Community Blog Feed, check out the Sitecore Slack Channel, hit up the Sitecore Stack Exchange or leave the Official Forums for more information.  It's a great time to be a Sitecore Developer!
