Hi,

Yesterday I cleared the Extending exam.

It had 48 questions with 700 as passing score.

I had referred the official training material of CRM 2011 as the training material for CRM 2013 are not released yet. Apart from that I had gone through different articles and videos to prepare for it.

There were very few questions that were specific to CRM 2013. Mostly they were around new methods added in Client SDK.

For someone who has a good hands-on experience in development in CRM 2011, passing this exam would not be that difficult.

Bye.

Hi,

Recently we wrote a plugin that was using RetrieveResponse class to get the information of an n – n relationship using Relationship class.

The issue that we faced over here is that the Entity property of RetrieveResponse is read only, we cannot set it. The option was to write the wrapper class over it and use the same wrapper class in the code and the unit test.

/// <summary>
 /// Wrapper class for retrieve response
 /// </summary>
 [DataContract(Namespace = "http://schemas.microsoft.com/xrm/2011/Contracts")]
 public class RetrieveResponseWrapper : OrganizationResponse
 {
 /// <summary>
 /// The _entity
 /// </summary>
 private Entity entity;

/// <summary>
 /// Initializes a new instance of the <see cref="RetrieveResponseWrapper"/> class.
 /// </summary>
 /// <param name="response">The response.</param>
 public RetrieveResponseWrapper(OrganizationResponse response)
 {
 try
 {
 this.entity = ((RetrieveResponseWrapper)response).Entity;
 }
 catch
 {
 this.entity = ((RetrieveResponse)response).Entity;
 }
 }

/// <summary>
 /// Gets or sets the entity.
 /// </summary>
 /// <value>
 /// The entity.
 /// </value>
 public Entity Entity
 {
 get
 {
 return this.entity;
 }

set
 {
 this.entity = value;
 }
 }
 }

 Hope it helps.

Suppose we need to query a n:n relationship and get details of both the entity records involved.

For this we can make use of Relationship and RelationshipQueryCollection class,

Suppose I have an entity named A  and it has n to n relationship with B  Entity.

This I how we can get the details all the A records associated with a particular entity B record.

i.e. Name of all the A records associated with a particular B entity record along with the  name of the B entity record.

</pre>
private void GetManytoManyRelationShipDetails(IOrganizationService _service, Guid entityBGuid)
 {
 // get offences records' name
 QueryExpression query = new QueryExpression("EntityA");
 ColumnSet cols = new ColumnSet();
 cols.AddColumn("EntityANameToBeRetreived");
 query.ColumnSet = cols;

// Relationship Name
 Relationship relationship = new Relationship("EntityA_EntityBRelationshipName");
 RelationshipQueryCollection relationshipColl = new RelationshipQueryCollection();
 relationshipColl.Add(relationship, query);

// get the legal issue record's name
 RetrieveRequest request = new RetrieveRequest();
 request.RelatedEntitiesQuery = relationshipColl;
 request.Target = new EntityReference("EntityB", entityBGuid);
 request.ColumnSet = new ColumnSet("EntityBNameToBeRetreived");
 RetrieveResponse response = (RetrieveResponse)_service.Execute(request);

string entityAName = string.Empty;

foreach (Entity entity in response.Entity.RelatedEntities[relationship].Entities)
 {
 entityAName += entity.Attributes["EntityAName"].ToString();
 }
 }

Hope it helps.
