wcf-data-services

I am using WCF data services and I have a few fields/properties that I want to "blank out" (set value to empty string or null) before sending back to client. For example: User table has password column which I do not want to pass the value to the client. This is one example, there are other such columns in the app that the value should be excluded for security/privacy reasons. Sorry for such a basic question, I'm new to WCF dataservices and have not found any promising leads yet. I've tried QueryInterceptors but no luck. Can someone point me in the right direction? Thanks IMO this is out of

I am trying to create a WCF Data Service over an Entity Framework Object context that exposes a number of System.TimeSpan properties. However, when I try to access the service, I get the following error: 'The property 'ScheduledDepartureTime' on type 'DepotRoute' is of type 'Time' which is not a supported primitive type.' I have tried using DataServiceConfiguration.RegisterKnownType(typeof(TimeSpan)) as well as DataServiceConfiguration.EnableTypeAccess(typeof(TimeSpan).FullName) but neither of these seem to make any difference - I still get the error... public static void InitializeService

I have a query like the following var query = (from x in NetworkDevices where x.Name == "blabla1" || x.Name == "blabla2" select x ); and i'm running it against an Odata endpoint, so it effectively gets translated into the following URL https://targetserver/endpoint.svc/NetworkDevices()?$filter=Name eq 'blabla1' or Name eq 'blabla2' So i want to dynamically add lots of those where filters... In C# i can just keep adding it to my query, but that isn't dynamic. I want to do it at runtime. If i was calling this from Javascript, well i can easily just update the URL as well. My Question, is in C#

I'm building WCF service and I would like to accept List as a parameter to one of my method. Here is my code: [ServiceContract] public interface IProductService { [OperationContract] int InsertProducts(List<Product> products); } [DataContract] [KnownType(typeof(List<Product>))] public class Product { [DataMember] public int ProductId{ get; set; } [DataMember] public string ProductName{ get; set; } [DataMember] public List<Product> Products { get; set; } } When I run service it gives me an error. This operation is not supported in the WCF, because it uses NameSpace.Product[] When sending a

I was reading about query interceptors . I was disappointed because thats more like a filter instead of an interceptor. In other words you can eather include records or not include them. You are not able to modify records for instance. If I want to create a query interceptor for my entity Users I could then do something like: [QueryInterceptor("Users")] // apply to table users public Expression<Func<User, bool>> UsersOnRead() { return cust => cust.IsDeleted == false; } What if I instead create the operation: NOTE IS VERY IMPORTANT TO HAVE THE OPERATION NAME JUST LIKE THE ENTITY NAME OTHERWISE

I'm using some code (available here on MSDN) to dynamically build LINQ expressions containing multiple OR 'clauses'. The relevant code is var equals = values.Select(value => (Expression)Expression.Equal(valueSelector.Body, Expression.Constant(value, typeof(TValue)))); var body = equals.Aggregate<Expression>((accumulate, equal) => Expression.Or(accumulate, equal)); This generates a LINQ expression that looks something like this: (((((ID = 5) OR (ID = 4)) OR (ID = 3)) OR (ID = 2)) OR (ID = 1)) I'm hitting the recursion limit (100) when using this expression, so I'd like to generate an expression
