Is there any information about the possibility of creation entity records in EntityMetadata? - dynamics-crm

Question

Here is the documentation EntityMetadata EntityType where all the properties of an entity are described.
I can not find any property that can describe the possibility to create a record of this entity type there.
How can I figure out that this entity type supports the creation of records?
As an example - activitypointer EntityType supports only Operations Supported GET, but in the entity metadata description, there is nothing related to it.

Answer 1

I reviewed this and I agree that there is no explicit entity metadata attribute akin to IsCreatable.
You could wrap an attempt to Create an empty entity of the type in a try / catch block.
When I ran:
var pointer = new ActivityPointer();
pointer.Create(svc);
The service threw this exception, even though the pointer entity contains no attributes:
System.ServiceModel.FaultException`1: 'The 'Create' method does not
support entities of type 'activitypointer'.'
This article lists the entities that support the IOrganizationService Create method under "Supported Entities".
