The cheat sheet is a refreshed version of the old one highlighting the new functionality in CRM 2013 and any removed or deprecated methods. You can download the A3 PDF from HERE or browse the SkyDrive folder for other versions.
I have created 3 versions:
An A3 version with all the details
A concise version that can fit in an A4
A black and white version of the A4
If you have any suggestions, I’m keen to hear your thoughts and publish newer versions.
