“Object of type can not be converted to type ‘IBusinessEntity’ ” exception with crm Early Binding
Hi,
You may come across below exception in Plug-Ins, while performing Create/Update operation using CRM early binding
Exception: Unhandled Exception: System.InvalidOperationException: Object of type ‘entity_name‘ can not be converted to type ‘IBusinessEntity’
Fix :-
- You need to add below line in your Plug-in project’s “AssemblyInfo.cs” file (Navigate to project folder and go to ..\Properties\AssemblyInfo.cs)
[assembly: Microsoft.Xrm.Sdk.Client.ProxyTypesAssemblyAttribute()]
AssemblyInfo.cs
- Clean and Rebuild the solution
- Register the plug-in assembly
Hope it helps 🙂

Hi,
Same error happens during workflow custom activity execution as well, though I added the assembly entry in workflow project as well.
