I fired up my SP2013 VM to do some simple tests tonight, I wanted to know if the REST services that I've built and demo'ed for SharePoint 2010 would run in SP2013.  Technically, they should.

So I deployed:

• stsadm -o addsolution -filename .\SPGSvcWp.wsp
• stsadm -o deploysolution -name SPGSvcWp.wsp -local -allowgacdeployment -allcontenturls

 

The files are copied to the services OK.

Deployed to ISAPI folder (_vti_bin)

 

DataService

 

REST service

SOAP service

 

Activate the features for the webpart:

 

Add the Web Part to the page:

 

The javascript needs a small modification - since the page in 2013 is loaded asynchronously.  But once I've re-attached the click event, the REST service itself works fine and returns the properties of the selected item.
