CRM Online Unable to Generate Early Bound Class using CRMSvcUtil - NullReferenceException

(0) ShareShare
ReportReport
Posted on by Sheharyar Hanif 5

Hi All,

We are trying to generate early bound class with CRMSvc.util, but we are getting System.NullReferenceException.

This is happening for entities only. For optionset and functions there is no issue like this.

    Yes we are still facing same issue. But alternative solution is that generate early bound class for only related entities (Entities used in the project). Do not  generate for all.

    With the latest XRM ToolBox version it should work.

    I'm having the very same problem!

    Is this a problem with early bound generator or something changed in CRM Online ?

    We have used Early bound generator. Getting same exception. We are able to generate classes for specific entities but not for all entities.
