SDK - Send Email Using Template with attachement

 InstantiateTemplateRequest instTemplateReq = new InstantiateTemplateRequest  
           {  
             TemplateId = templateId,  //template guid
             ObjectId = incidentId,   // template type id
             ObjectType = "incident"  
           };  
 InstantiateTemplateResponse instTemplateResp = (InstantiateTemplateResponse)service.Execute(instTemplateReq);  
 Entity instTemplate = (Entity)instTemplateResp.EntityCollection.Entities[0];  
 Guid emailGuid = service.Create(instTemplate);  
 //Add attachement  
 Entity emailAttachment = new Entity("activitymimeattachment");  
 //attachement in byte[]  
 emailAttachment["body"] = Convert.ToBase64String(attachement);  
 emailAttachment["objectid"] = new EntityReference("email", emailGuid);  
 emailAttachment["objecttypecode"] = "email";  
 emailAttachment["filename"] = item.Name;  
 service.Create(emailAttachment);  //Creates attachement to email
 SendEmailRequest sendEmailReq = new SendEmailRequest()  
           {  
             EmailId = emailGuid,  
             IssueSend = true  
           };  
  SendEmailResponse sendEmailResp = (SendEmailResponse)service.Execute(sendEmailReq);  

Retrieve EntityImage using SDK

In this example we will retrieve contact entity image

var Contact=Service.Retreive("contact","GUID",new ColumnSet(true));

if(Contact.Attributes.Contains("entityimage"))

{

byte[] entityimage=Contact["entityimage"] as byte[];

}

the above piece of code has no issues and ideally should Retreiveall the attributes of the contact as new ColumnSet(true) is specified but this will not get the entity image 

When you use RetrieveMultiple or Retrieve the EntityImage is not included when the ColumnSet.AllColumns property is set to true. Because of the potential size of data in this attribute, to return this attribute you must explicitly request it.

The binary data representing the image isn’t returned using the deprecated ExecuteFetchRequest class. You should use RetrieveMultipleRequestinstead.

CRM 2016 Web API Retrieve Attribute Names By Entity Name

GetEntityMetaData function will retrieve the list of attributes from he Account entity.

 function GetEntityMetaData() {

Retrieve Team Members using RetrieveMultipleRequest

As we know that CRM Sdk deprecated RetrieveMembersTeamRequestmessage (https://msdn.microsoft.com/en-us/library/gg309360.aspx). So there is only way to retrieve Team Members using RetrieveMultipleRequest. and here is the method for the same. It works for the AccessTeam too.

 private static void RetrieveTeamMembers(IOrganizationService service, EntityReference teamEntityReference)  
 {  
 QueryExpression userQuery = new QueryExpression("systemuser");  
 userQuery.ColumnSet = new ColumnSet("fullname");  
 LinkEntity teamLink = new LinkEntity("systemuser", "teammembership", "systemuserid", "systemuserid", JoinOperator.Inner);  
 ConditionExpression teamCondition = new ConditionExpression("teamid", ConditionOperator.Equal, teamEntityReference.Id);  
 teamLink.LinkCriteria.AddCondition(teamCondition);  
 userQuery.LinkEntities.Add(teamLink);  
 EntityCollection retrievedUsers = service.RetrieveMultiple(userQuery);  
 foreach (Entity user in retrievedUsers.Entities)  
 {  
 Console.WriteLine(String.Format("User: {0} with GUID {1}", user.GetAttributeValue<string>("fullname"),  
 user.Id));  
 }  
 }
