Sample: Dump attribute metadata to a file


Applies To: Dynamics CRM 2015

This sample code is for Microsoft Dynamics CRM 2015 and Microsoft Dynamics CRM Online 2015 Update. Download the Microsoft Dynamics CRM SDK package. It can be found in the following location in the download package:



For more information about the requirements for running the sample code provided in this SDK, see Use the sample and helper code.


This sample shows how to write out all the attribute metadata to an XML file. It uses the RetrieveAllEntitiesRequest message.

The following sample creates a new file at \Entities\bin\Debug\AllAttributeDesc.xml. You can open this file in Microsoft Office Excel to see a tabular report. You can easily look up information such as which attributes can be specified in a create, retrieve, or update operation. This information can also be found in the “EntityName Entity Attribute Metadata” topic for each entity.
