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

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.

    try to use Early Bound Generator (it's a plugin available inside XrmToolBox)

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

    I'm having the very same problem!

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

    Hello, 

    This started happening for me too just before christmas. Out of nowhere..

    No solution yet?

    With the latest XRM ToolBox version it should work.

    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.

    This issue was resolved with the nuget release NuGet Gallery | Microsoft.CrmSdk.CoreTools 9.1.0.68  this was release the 2ed week of January. 
    Daryl's XRM toolbox addin was also updated 

    thanks
