I am using Visual Studio 2010, Visual C#, .NET framework 4.0.
I have app in IIS. All my methods looks something like this:
[WebGet(ResponseFormat = WebMessageFormat.Json)]
public string Select()
return "Hello World";
And the work fine - the only problem is how to return DataTable in Json format?
I've found this topic: http://schotime.net/blog/index.php/2008/07/27/dataset-datatable-to-json/
But, nothings comes back from the server. The dictionary<string, object> is created, but nothing is returned from server.
I need to return DataTable in Json format and the (on the client) convert this back to DataTable and show in DataGrid (Windows forms).
