OData Type Provider with SharePoint 2010

‘Type Providers’ is an extremely cool F# feature that was introduced with F 3.0 and shipped with VS 2012 and .NET 4.5. You can find Type providers’ explanation  here and details about OData type provider here.

It maybe not a news, but OData Type Provider works pretty well with SharePoint 2010.

SharePoint 2010 has a OData Service. You can find mode details about this service at the MSDN article Query SharePoint Foundation with ADO.NET Data Services

One special thing that distinguishes SharePoint service from the others is that you should be authenticated. Just set your credentials into created data content before using it. You can find full code sample below.

#r "FSharp.Data.TypeProviders.dll"
#r "System.Data.Services.Client.dll"

open Microsoft.FSharp.Data.TypeProviders
open System.Net

type sharepoint = ODataService<"http://server_name/_vti_bin/listdata.svc">
let web = sharepoint.GetDataContext() in
    web.Credentials <-
        (NetworkCredential("user_name", "password", "domain") :> ICredentials)

    |> Seq.iter (fun item -> printfn "%A : %s" item.Modified item.Name)
