Posted on by Khaled Rimawi 145

Hi,

I have generated Xrm for my CRM instance , when i use the classes in it which represents schema names of an entities , exception occurs . For example, i have entity called "Class" and it's schema name is "new_class", when i create a query like this :

using (var orgService = crmConnection.GetContext())
{
  return (from i in orgService.CreateQuery<new_instructorplacement>()
          where i.Id == id
          select i).FirstOrDefault();
                   
}

exception occurs : {"Unable to cast object of type 'Microsoft.Xrm.Sdk.Entity' to type 'new_instructorplacement'."}. Any one knows what might be the problem ?

    Hi,

    Can you share the definition of your class? As mentioned above, based on the error message, it looks like new_instructorplacement doen't inherit from Microsoft.Xrm.Sdk.Entity.

    Hello,

    Just try to do it in late bound to see the result and post it here plz  :

    return (from i in orgService.CreateQuery("new_instructorplacement")

         where i.GetAttributeValue<Guid>("new_instructorplacementid")==id

          select i).FirstOrDefault();

    "Unable to cast object of type 'Microsoft.Xrm.Sdk.Entity' to type 'new_instructorplacement" suggests that new_instructorplacement is not an considered as an entity

    Hi Khaled Rimawi,

    How did you generate the classes? I recommend creating early bound entity classes is with the code generation tool (CrmSvcUtil.exe). You can find information on this here.
