title: How to retrieve a Entity without Guid in Dynamics 365 SDK?
body: <p>Well, I have this command: <code>IOrganizationService.Retrieve(String entityName, Guid ID, ColumnSet columnSet)</code> reference: <a href="https://msdn.microsoft.com/en-us/library/microsoft.xrm.sdk.iorganizationservice.retrieve.aspx" rel="nofollow noreferrer">IOrganizationService</a></p>
  
  <p>I tried the SDK Code Samples but the retrieve information is made using the Guid when this create a record, like here: <code>Guid _accountId = orgService.Create(account);</code></p>
  
  <p>I want to get this <code>Guid</code> using the name of the Account(Entity), how can I do that?</p>
