I would love to see it done with Entity Framework as there might be some tricky things like validation and stuff. But good job!

I think it would be better if this article include with jQuery code like in the first introductory article.

It should be mentioned somewhere in this tutorial.

I know it is still in beta, and you guys ahve done a good job in publishing the tutorials and samples.

The id parameter is not getting populated from the request URI but instead from the Contact object passed in the request body. Not good. :-(

For example, if I want to get contacts with id 1, 3 and 8.

I appreciate this is not an article on patterns but some newer guys might not be aware that you are removing the loose coupling of an interface by assigning a concrete instance inline?

static readonly IContactRepository _repository = new ContactRepository();

However, I am finding that regarding this.... var response = Request.CreateResponse<Product>(HttpStatusCode.Created, item); ....causes a CTE of something like "CreateResponse" cannot accept typed arguments.... and the non-typed version only takes 1 param, the StatusCode. Also, I am finding that for this.... string uri = Url.Link("DefaultApi", new { id = item.Id }); ....the UrlHelper does not have a "Link" method... so I am skipping that part. Regardless, it is a good article. Thanks. -- Mark Kamoski

How can one call this from the code-behind of an ASP.NET ASPX page using C# and POST? Can you show a quick code sample? I have RetrieveAll and RetrieveOne working with WebApi. But, for some reason, I cannot get the CreateOne to wire-up with POST, and the service call just times out. Etc. Please advise. Thanks. -- Mark Kamoski

Are there any plans to fix these?

Request.CreateResponse<Product> and Url.Link(...

don't build. Any ideas?

I decided to download the project code from the top of this page. When I did that and opened it, I recieved error messages from VS that some components (I'm sorry, I don't remember the exact ones and didn't write it down) were not installed, and it offered to install them for me. It had something to do with MVC3 and also something about ASP.NET in general. This may have been because I installed VS 2010 recently, never had MVC3 on this and directly loaded MVC 4, so I think some components were missing.

Anyway, that fixed it. If you are getting the build problem, please try opening the provided solution. If you do, please post here as to what packages needed to be loaded. Thanks!

Are we expected to ignore these?

You can add a SuppressMessage attribute to suppress the warning. Thanks for pointing that out!

I noticed that HttpResponseException is one of the things that changed between the Beta and the RC. Do you know if there will be more changes to HttpResponseException? I admit I'm a little leery of just suppressing this warning (for the whole method), though I suppose I can mitigate the impact somewhat by isolating it.

Great tutorial btw.

check your code,

correct is " public class ProductsController : ApiController "

but default vs created is " public class ProductsController : Controller "

I am trying to find a sample which will show me how to build an OData service which will allow be to use the OData specified query URIs to query my EF data model (www.odata.org/#QueryStringOptions). Any ideas?

Although you give good example code (for those getting the error on Request.CreateResponse - Using System.Net.Http), but you give no example models or anything. This is pretty much on the useless end of worthless. It mimics much of the useless Microsoft MSDN writings that do nothing but confuse and frustrate the developer.

You go into great detail of the Get methods but end it with a slight mention of the Delete method. Update gets even less attention.

Worthless.

For the PUT and DELETE methods, I figured they are reasonably straightforward, once you've seen the pattern for GET and POST. The main considerations are (a) do you return anything in the response body; (b) what status code to return. But if I left out something that seems important, let me know.

I should add: There are definitely other things to consider, e.g. model validation, that I didn't cover here.
