Since the OData endpoint was released with CRM 2011, I’ve used CRM OData Query Designer developed by my fellow MVP Rhett Clinton. Today, I was working on a brand new online instance of CRM 2015 and I trying to import a lovely tool into CRM when I got a message that solutions developed for CRM 2011 could not be imported into CRM 2015. I started to look for alternatives and found a brilliant solution developed by another fellow MVP – Jason Lattimer. The great advantage of CRM REST Builder is that you can get the complete code of calls using different frameworks developed for Dynamics CRM. So try, use, and love this tool – CRM REST Builder.
