CRM 2011 – Update Rollup 7 for Microsoft Dynamics CRM 2011 (KB 2600643)

The rollups keep rolling up for CRM 2011 and this means we are closers to R8 and the big enhancements coming our way.

I have updated the wiki page with the all the rollup numbers and version which you can see by clicking the link below

CRM 2011 Build and version numbers


To download rollup 7 click the release below

Version: 05.00.9690.2165

The KB article is KB2600643

Just to remind you, you will need to have rollup 6 installed to use this.

It seems to have a lot of fixes in this release but I can’t really make out any new major functionality.



CRM 2011 – QueryExpressions where a field is null

I had to write some code today which retrieved some entities which didn’t have a value in a field, so basically I had to write a query to find all the entities which had a null value.

I finally found some sample code on the Microsoft SDK

FilterExpression null_filter = new FilterExpression(LogicalOperator.And);
null_filter.FilterOperator = LogicalOperator.And;
null_filter.AddCondition("leadid", ConditionOperator.Null);

below is my full code.  I am selecting my custom charges entity where the invoice lookup value is null

public IEnumerable<meta_charge> getCharges(IOrganizationService service)

ConditionExpression condition1 = new ConditionExpression();

condition1.AttributeName = "new_invoice";
condition1.Operator = ConditionOperator.Null;
FilterExpression filter1 = new FilterExpression();

QueryExpression query = new QueryExpression(new_charge.EntityLogicalName);
query.ColumnSet = new ColumnSet(true);


EntityCollection result1 = service.RetrieveMultiple(query);

IEnumerable<new_charge> charges = result1.Entities.Cast<new_charge>();
return charges;

catch (Exception)
// You can handle an exception here or pass it back to the calling method.
return null;
