I have a Business Logic Layer (BLL) and a Data Access Layer (DAL) that used for WinForms, WebForms, and ASP.NET MVC projects in the past. The objects implement all kinds of interfaces. Now I would like to tackle ADO.NET Data Services. I am trying something simple like the following, but it's not rendering my service. Am I totally m...
How can I mock a DataServiceQuery for unit testing purpose? Long Details follow: Imagine an ASP.NET MVC application, where the controller talks to an ADO.NET DataService that encapsulates the storage of our models (for example sake we'll be reading a list of Customers). With a reference to the service, we get a generated class inheritin...
Hey all! There are a number of questiosn on StackOverflow that ALMOST hit this topic head on, but they are either for other technologies, reference obsolets information or don;t supply an answer that I can suss out.

I am really confused about when to use WCF and when to use ADO data services in my website ajax calls. I always make my javascript code call a webservice to get data from server "ajax". But while reading in both WCF and ADO data service, i am not sure when to use each and when not use?, and if they replace each other in my case? or can...
I have a database I'd like to create an entity from, and then generate RESTful output. My objective is to add a property to one of the tables once it becomes an entity. The data for that property would be one I'd come up with through calculations done on a few different fields in the table. From there, the code generator would create ...
I am uisng Silverlight 3 and ADO.NET Data Services with a cusotm-built Model (separate project) and DAL (separate project)) in place. Within my Silverlight project, I create a [Service Reference] that references my .svc file that in turn points to my Model. Here's my question: I would like to use the rich features of DataAnnotations ...
I've been learning by doing with ADO.Net Data Services (Astoria) for the last couple of months, and while I like the technology the learning has been a real trial. Information that you need to use them effectively is spread over MSDN documentation, articles, blog posts, support forums and of course StackOverflow. This question is a place...
I am configing ado.net dataservice in public static void InitializeService(IDataServiceConfiguration config) { // config.UseVerboseErrors = true; // TODO: set rules to indicate which entity sets and service operations are visible, updatable, etc. // Examples: ...
I am trying to build an ADO.NET Data Service with lots of entities and a few service operations. On one side I created a ASP.NET Web Application, in which an ADO.NET Entity Data Model and an ADO.NET Data Service are located. On the other side I created a second ASP.NET Web Application that has a Service Reference to the Data Service. En...
I'm trying to perform a simple query using ADO.NET Data Services running against LINQ to NHibernate. I can execute this query var query = _context.CreateQuery("FileDTOs") .Where(file => file.Name.Contains("name")); I can run a similar query directly against LINQ to NHibernate without issues, but when I pass the same q...
This question is a bit of a two parter for .Net data services. This is the function signature I'm trying to achieve: /// <summary> /// Returns Descriptions for any asset in the given assetIDs. /// </summary> [WebGet] public IQueryable<Description> FindDescriptionForAssets(int[] assetIDs); I'm trying to create a custom service operat...
We have an existing application that relies heavily on stored procedures and untyped DataSets. I'd like to maintain that flexibility, but leverage the REST capabilities of ADO.NET Data Services. However, when I attempt to use the following code to expose the DataSet to ADO.NET Data Services: namespace NewTechnologyDemo { public class ...
I have a application where the validation is done in the web server side (in the page). and the control is passed to the sl client. The SL client makes call to the ado.net data services for its query and wcf service for writing to the DB. How should I handle the security of the ado.net data services? I use http://programmerpayback.com/2...
I'm looking to create a service (based on .NET Fx 3.5 or 4.0) that exposes data via Atom and enables AtomPub (so that I can update using Windows Live Writer). There looks to be two options: Use ADO.NET Data Services. From what I can tell this is the easiest to get working, but requires EF (I'm using LinqToSQL - although I know there ...
There's no obvious entry point for implementing a custom provider for an ADO.NET Data Service using IDataServiceMetadataProvider, and then telling a Data Service to use that provider. Has anyone had any luck in this area? I've tried implementing this interface on my Data Source class, but none of my breakpoints are hit. There is also no ...
I have an ADO.NET data service exposed by a .NET app (not IIS) which is consumed by a .NET client app. Some calls to this data service return large amounts of data. I'd like to compress the XML data on the wire to reduce payload and improve performance. Is this possible? ...
Our team is evaluating using WCF Data Services (formerly ADO.NET Data Services), and have determined we'll have to create a Custom Data Service Provider. Where can we find a sample implementation of the two required interfaces: IDataServiceMetadataProvider and IDataServiceQueryProvider? EDIT: Note that a "WCF Custom Data Service Provid...
I am trying to write REST web service through which our clients can upload a file on our file server. IS there an example or any useful links which I can refer for any guidance? I haven't seen many examples of POST operation using ADO.NET data services available. ...
I want to store per-thread data in an ADO.NET Data Service. Is it safe to use the ThreadStatic attribute on my thread-specific static variable, or will I run into problems? My concern is that my ThreadStatic variable(s) won't be garbage collected after the request is completed and the thread dies. If there's a better way to do what I'm...
