Using CRM 2011 SOAP and REST endpoints with Silverlight
To communicate with CRM 2011 from Silverlight application you can either use SOAP or REST endpoints.
URL’s for both endpoints will be available under “Developer Resources” section (Go to Settings -> Customizations -> Developer Resources)
SOAP and REST endpoints
Below are the important points on usage & limitations of both endpoints
Using REST endpoint with Silverlight
- CRM 2011 uses the WCF Data Services framework to provide an OData endpoint that is a REST-based data service.
- This endpoint is called the Organization Data Service
- It supports early bound entity types so that the coding will be easy (i.e., you can instantiate contact c=new contact(); c.name=”Rajeev”)
- Limitations
- Only Create, Retrieve, Update, and Delete actions can be performed on entity records
- You need to regenerate the proxy every time you change the entity schema (Ex – If you create a new entity or attribute)
- You cannot use late binding to work with custom entities that were not included when proxy generated.
- Here is the MSDN article Walkthrough REST in Silverlight
Using SOAP endpoint with Silverlight
- Unlike the REST endpoint, the SOAP endpoint uses the Organization service
- You can do all the operations with SOAP endpoint
- Here is the MSDN article Walkthrough SOAP in Silverlight
- SOAP does not provide early bound entity types natively but here is article to how to use early bindings with SOAP

Assign record using JScript in CRM 2011
Hi,
Below is the Jscript to assign a record to particular User using SOAP.
function AssignRecord(Assignee, Target, entityName) {
var request = “<s:Envelope xmlns:s=\”http://schemas.xmlsoap.org/soap/envelope/\”>”;
request += “<s:Body>”;
request += “<Execute xmlns=\”http://schemas.microsoft.com/xrm/2011/Contracts/Services\””;
request += ” xmlns:i=\”http://www.w3.org/2001/XMLSchema-instance\”>”;
request += “<request i:type=\”b:AssignRequest\””;
request += ” xmlns:a=\”http://schemas.microsoft.com/xrm/2011/Contracts\””;
request += ” xmlns:b=\”http://schemas.microsoft.com/crm/2011/Contracts\”>”;
request += “<a:Parameters xmlns:c=\”http://schemas.datacontract.org/2004/07/System.Collections.Generic\”>”;
request += “<a:KeyValuePairOfstringanyType>”;
request += “<c:key>Target</c:key>”;
request += “<c:value i:type=\”a:EntityReference\”>”;
request += “<a:Id>” + Target + “</a:Id>”;
request += “<a:LogicalName>” + entityName + “</a:LogicalName>”;
request += “<a:Name i:nil=\”true\” />”;
request += “</c:value>”;
request += “</a:KeyValuePairOfstringanyType>”;
request += “<a:KeyValuePairOfstringanyType>”;
request += “<c:key>Assignee</c:key>”;
request += “<c:value i:type=\”a:EntityReference\”>”;
request += “<a:Id>” + Assignee + “</a:Id>”;
request += “<a:LogicalName>systemuser</a:LogicalName>”;
request += “<a:Name i:nil=\”true\” />”;
request += “</c:value>”;
request += “</a:KeyValuePairOfstringanyType>”;
request += “</a:Parameters>”;
request += “<a:RequestId i:nil=\”true\” />”;
request += “<a:RequestName>Assign</a:RequestName>”;
request += “</request>”;
request += “</Execute>”;
request += “</s:Body>”;
request += “</s:Envelope>”;
// Get server URL
var serverUrl = Xrm.Page.context.getServerUrl();
var req = new XMLHttpRequest();
req.open(“POST”, serverUrl, true)
// Responses will return XML. It isn’t possible to return JSON.
req.setRequestHeader(“Accept”, “application/xml, text/xml, */*”);
req.setRequestHeader(“Content-Type”, “text/xml; charset=utf-8”);
req.setRequestHeader(“SOAPAction”, “http://schemas.microsoft.com/xrm/2011/Contracts/Services/IOrganizationService/Execute”);
req.onreadystatechange = function () { assignResponse(req); };
req.send(request);
}
// This function gets called after the execution
function assignResponse(req) {
if (req.readyState == 4) {
if (req.status == 200) {
alert(“Success !!!”);
}
else {
alert(“Error – ” + req.responseXML);
}
}
}
How Do I Call this function :-
- Pass User Id, Record Id and Entity name to the function
var userId = “” // GUID of user whome to assign the record
var recordId = “” // GUID of record you want to assign
var entityName = “” // Entity name the record
AssignRecord(userId,recordId,entityName);
Hope it helps 🙂
