 ## Client versus Server Execution  
  The client executes a query in two parts. Whenever possible, expressions in a query are first evaluated on the client, and then a URI-based query is generated and sent to the data service for evaluation against data in the service. Consider the following LINQ query:  
 
-<!-- TODO: review snippet reference  [!CODE [Astoria NorthwindClient#LinqQueryClientEvalSpecific](Astoria NorthwindClient#LinqQueryClientEvalSpecific)]  -->  
+ [!code-csharp[Astoria Northwind Client#LinqQueryClientEvalSpecific](../../../../samples/snippets/csharp/VS_Snippets_Misc/astoria northwind client/cs/source.cs#linqqueryclientevalspecific)]   
+ [!code-vb[Astoria Northwind Client#LinqQueryClientEvalSpecific](../../../../samples/snippets/visualbasic/VS_Snippets_Misc/astoria northwind client/vb/source.vb#linqqueryclientevalspecific)]   
 
  In this example, the expression `(basePrice – (basePrice * discount))` is evaluated on the client. Because of this, the actual query URI `http://localhost:12345/northwind.svc/Products()?$filter=(UnitPrice gt 90.00M) and substringof('bike',ProductName)` that is sent to the data service contains the already calculated decimal value of `90` in the filter clause. The other parts of the filtering expression, including the substring expression, are evaluated by the data service. Expressions that are evaluated on the client follow common language runtime (CLR) semantics, while expressions sent to the data service rely on the data service implementation of the [!INCLUDE[ssODataShort](../../../../includes/ssodatashort-md.md)] Protocol. You should also be aware of scenarios where this separate evaluation may cause unexpected results, such as when both the client and service perform time-based evaluations in different time zones.
