LINQ to JSON in .net 4.0 Client Profile

How will I use LINQ for JSON in a .net 4 client profile in C #. I would like to request some json answers as shown in the msdn blog post without writing out a contract (datacontract, servicecontract, etc.). I really only need to request (read) the response, I do not need to modify the json response. (Would datacontract also be faster than LINQ for JSON?)

Alternatively, I could use XML or the full .net 4 framework, but I hope this can be avoided. I can use external libraries if this is better than installing the whole structure.

JSON.net is pretty popular and it seems you like it.

If your service is used by Ajax clients (jQuery), you will get better performance using JSON.

Another recommendation; To get rid of the same domain policy, I recommend that you enable the crossDomainScriptAccessEnabled function:

<webHttpBinding> <binding name="myHttpBinding" crossDomainScriptAccessEnabled="true" /> </webHttpBinding>

Regarding DataContract; DataContract is not needed in your script.

Code example:

  • Your service:

     [ServiceContract] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] public class BlogService { [OperationContract] [WebGet(ResponseFormat = WebMessageFormat.Json)] public List<Article> GetBlogArticles() { return Article.GetDummyArticles.ToList(); } }

  • Article class (excerpt):

     public class Article { public string Title { get; set; } public string Body { get; set; } public static IEnumerable<Article> GetDummyArticles() { yield return new Article { Title = "Article 1", Body = "sdlkfjsdlkfjskl" }; yield return new Article { Title = "Article 2", Body = "sfsfsdfd23434wfdfsfdfkfjskl" }; } }

For your scenario, I actually cannot find a reason to use any (third-party) library, since WCF4 already contains native JSON support with or without Padding.
