How to add a new entity to MS CRM - dynamics-crm-2011

Question

I want to create an new entity in crm
OrganizationService_orgService ;
var connection = CrmConnection.Parse(conn);
_orgService = new OrganizationService(connection);
Entity newEntity = new Entity("this_is_a_new_entity");
Guid newEntityID = _orgService.Create(newEntity);
I wrote the above code where the conn is the connection string in the format which is correct (i checked)
string conn = "Url=https://damnidiot.crm5.dynamics.com; Username=XXXXXXXX#damnidiot.onmicrosoft.com; Password=XXXXXXXXX;";
but when i run the code i get an exception {"The entity with a name = 'this_is_a_new_entity' was not found in the MetadataCache."}
i am asuming i got this error because my crm does not have defination for the entity this_is_a_new_entity .
Is it possible to retrive And update the metadata cache of my MS CRM ?(I AM USING Microsoft Dynamics CRM 2013 )

Answer 1

If you use new Entity("new_entity_name") you are telling the code that you want to create a new record inside the already existing entity named new_entity_name.
To create a new entity altogether you have to issue a CreateEntityRequest (link to MSDN)
// PART OF THE LINKED SAMPLE
CreateEntityRequest createrequest = new CreateEntityRequest
{
//Define the entity
Entity = new EntityMetadata
{
SchemaName = _customEntityName,
DisplayName = new Label("Bank Account", 1033),
DisplayCollectionName = new Label("Bank Accounts", 1033),
Description = new Label("An entity to store information about customer bank accounts", 1033),
OwnershipType = OwnershipTypes.UserOwned,
IsActivity = false,
},
// Define the primary attribute for the entity
PrimaryAttribute = new StringAttributeMetadata
{
SchemaName = "new_accountname",
RequiredLevel = new AttributeRequiredLevelManagedProperty(AttributeRequiredLevel.None),
MaxLength = 100,
Format = StringFormat.Text,
DisplayName = new Label("Account Name", 1033),
Description = new Label("The primary attribute for the Bank Account entity.", 1033)
}
};

To create new entity you should use Create Entity Request. Your code creates record of this_is_a_new_entity.
