Custom Logic and Proxy Classes in ADO.NET Data Services
I've just read "Injecting Custom Logic in ADO.NET Data Services" and my next question is, How do you get your [WebGet] method to show up in the client-side proxy classes? Sure, I can call this directly (RESTfully) with, say, WebClient but I thought the strong typing features in ADO.NET Data Services would "hide" this from me auto-magical...
oData and PHP without control of the server
B"H Is there a way to query oData from PHP without needing to change the php.ini? i.e. if I only have permission to upload files into the public web directory, and I do not have a shell account to run the scripts to generate the proxy classes, is there a way I can use curl directly to query an oData database? Or could I use only part o...
Using LinqExtender to make OData feed fails
A pretty simple question, has anyone here tried to make a OData feed based on a IQueryable created with LinqExtender? I have created a simple Linq-provider that supports Where, Select, OrderBy and Take and wanted to expose it as an OData Feed. I keep getting an error though, and the Exception is a NullReference with the following StackT...
WCF Data Services consuming data from EF based repository
We have an existing repository which is based on EF4 / POCO and is working well. We want to add a service layer using WCF Data Services and looking for some best practice advice. So far we have developed a class which has a IQueryable property and the getter triggers the repository 'get all users' method. The problem so far have been tw...
OData EndPoint/DataService Using IEnumerable<IQueryable>
I am using NHibernate with NHibernate.Linq, and have a bunch of dynamically loading modules each with their own POCO's and Mappings (ClassMap<POCO>). I have created OData services before, but normally with a datacontext and IQueryable as Properties/Getters. What I want is to create the service by passing in IEnumerable, into the constr...
Can't submit new object to WCF DataService because of Primary Key constraint
I've got a SQL database that uses Guid's for PK's and upon insert, it generates a NewId(). I have an EF data context setup pointing to that database with the primary keys setup with the Entity key:true, Setter:private and StoreGeneratedPattern:Identity because I want the DB to manage the keys and not have code set the PK property. I h...
Return Count from Netflix oData Service When the LINQ Count() Method Doesn't Work
Is there a way to use a LINQ expression to request a Count query from the Netflix oData service in Silverlight 4? The Netflix documentation shows that you can return counts by appending $count to a request for a collection, but a URL like this: http://netflix.cloudapp.net/Catalog/Genres/$count Is not generated from an expression like...
oData RIA PowerPivot Large Message Size
Hi, I was playing with powerpivot to directly load 3 million rows from a sql database and performance is suprisingly good. I tried generating a simple oData service by using vs2010 and silverlight RIA services and access that from powerpivot. Which works with small numbers of rows but blows up on the server if a single method tries to ...
Updating/Inserting multiple rows using jQuery and OData (WCF Data Services)
I have three tables, Template, Fields and TemplateFields. TemplateFields holds the selected fields for each template. I need to update TemplateFields when the user is finished selecting the fields. The only way I can see to do this is by deleting all the TemplateFields for that Template and then add them one by one in separate requests...
Controlling ASP.NET output cache memory usage
I would like to use output caching with WCF Data Services and although there's nothing specifically built in to support caching, there is an OnStartProcessingRequest method that allows me to hook in and set the cacheability of the request using normal ASP.NET mechanisms. But I am worried about the worker process getting recycled due to ...

Is there a more easy way to create a WCF/OData Data Service Query Provider?
I have a simple little data model resembling the following: InventoryContext { IEnumerable<Computer> GetComputers() IEnumerable<Printer> GetPrinters() } Computer { public string ComputerName { get; set; } public string Location { get; set; } } Printer { public string PrinterName { get; set; } public string Location { get; set; ...
OData and custom WCF WebGet methods
I've created an OData endpoint (using entity framework, WCF data service) and added a custom test WebGet test method like so: [WebGet(UriTemplate = "{text}")] public IQueryable<string> SplitString(string text) { if (text == null) throw new DataServiceException("text not specified"); var result = (from s in t...
Consuming Odata service with .NET Compact Framework
Hi, I'd like to consume an odata service with a .NET Compact Framework 3.5 client application. What's the easiest way to do that? There are are clients for various programming languages in the odata SDK, but I could not find anything related to the compact framework. Am I missing something or do I have to use plain old HttpWebRequests...
Request all titles by actor using LINQ to Netflix OData
I'm experimenting with LINQPad to use LINQ to query the Netflix OData. I'm trying to search for all films with a particular actor in. For example: from t in Titles from p in t.Cast where p.Name == "Morgan Freeman" select t.Name this results in: NotSupportedException: Can only project the last entity type in the query being transl...
How to deal with the limited Linq support of OData (Open Data Protocol)
I have a software, which uses a lot of Linq-to-SQL. Recently, I want to migrate to OData / WCF Data Service architecture. But I met too many problems in the Linq support of OData - it is so limited. I have to modify most of my Linq statements and test them thoroughly again. I am wondering whether there is a system way to solve such a pr...
Can't get the JSONP workin' with WCF Data Services...
What am I missing here? It seems from all that I read and watched, exposing JSON from a WCF Data Service should be as easy as adding the '[JSONPSupportBehavior]' directive in front of the Service Class. Problem is VS2010 doesn't recognize 'JSONPSupportBehavior'. Is there a reference I am missing? Seemed like, from alll the articles, it w...
Can I expose MySQL data using PHP and OData?
As I understand it, OData is just a standardized way to expose relational data RESTfully. If I've got a PHP application, it should be able to process those RESTful requests and manipulate a MySQL database based on the request data and then return an ATOM feed. First, are the preceeding statements correct? Second, does a PHP library to...
OData / WCF Data Service - HTTP 500 Error
I have created an OData/WCF service using Visual Studio 2010 on Windows XP SP3 with all current patches installed. When I click on "view in browser", the service opens and I see the 3 tables from my EF model. However, when I add a table name ("Commands" in this case) to the end of the query string, rather than seeing the data from the...
