Created Entity using plugin has no valid Entity.Id Value - entity

Question

I have managed to execute the statement to create an entity successfully without any errors, but the id of the entity remains as default 00000000-0000-0000-0000-000000000000. In CRM, the created entity did not appear too.
I have not included all fields in the entity, and only inputting 1 field for testing.
Is it due to some mandatory fields not being filled, that is causing the above false positive that the entity is created?
Below is my code snippet:
Call CreateCase(row)
foreach (DataRow row in caseTable.Rows)
{
Entity caseEntity = helper.GetCasebyID((string)row[Excel.ID]);
if (caseEntity == null)
{
caseEntity = CreateCase(row);
}
}
CreateCase(row):
private Entity CreateCase(DataRow row)
{
Entity caseEntity = new Entity("new_case");
if (!(string.IsNullOrEmpty(row[Excel.sourcename].ToString().Trim())))
{
caseEntity.Attributes[Case.sourcename] = row[Excel.sourcename];
}
helper.GetOrganizationService().Create(caseEntity);
Logger.Info(caseEntity.LogicalName + " " + caseEntity.Id + " created. ");
//output: case 00000000-0000-0000-0000-000000000000 created.
}
Helper class:
public class Helper
{
private OrganizationServiceProxy _proxy;
private IOrganizationService _org;
public IOrganizationService GetOrganizationService()
{
if (_org == null)
{
var credential = new ClientCredentials();
credential.Windows.ClientCredential.Domain = ConfigurationManager.AppSettings["Domain"];
credential.Windows.ClientCredential.UserName = ConfigurationManager.AppSettings["Username"];
credential.Windows.ClientCredential.Password = Decrypt(ConfigurationManager.AppSettings["Password"]);
Uri organizationUri = new Uri(ConfigurationManager.AppSettings["OrganizationUri"]);
Uri homeRealmUri = null;
_proxy = new OrganizationServiceProxy(organizationUri, homeRealmUri, credential, null);
_proxy.ServiceConfiguration.CurrentServiceEndpoint.Behaviors.Add(new ProxyTypesBehavior());
_org = new OrganizationService(_proxy);
}
return _org;
}
}

You should not use the same object to check if record created or guid is available.
Below line in your code return Guid datatype and not subset of object.
helper.GetOrganizationService().Create(caseEntity);
Also when you create a record, Try to add atleast Primary name attribute value.
In your case it shall be new_name
So you should have your code as
Guid newlyCreatedCaseRecord = helper.GetOrganizationService().Create(caseEntity);
Logger.Info(caseEntity.LogicalName + " " + newlyCreatedCaseRecord + " created. ");
You could also fetch newly created Record from Database as Entity object.
Guid newlyCreatedCaseRecord = helper.GetOrganizationService().Create(caseEntity);
Entity newlyCaseEntity = helper.GetOrganizationService().Retrieve("new_case",newlyCreatedCaseRecord , new ColumnSet(true));
Logger.Info(newlyCaseEntity .LogicalName + " " + newlyCaseEntity.Id + " created. ");
Note: There can be Typo in code, try validating in Visual studio.
