publish object to facebook wall with open graph api using asp.net

[nexia]

I have defined the custom action and object for my app on facebook.I have also kept the meta tags and made the page as open graph object.How can i make a request to action to publish my object on facebook wall.I did lot of research but could not find any example in C#/Asp.net for making an action request to publish my object on facebook.I should be able to make that request from server side and post the object on facebook timeline.The existing documentation on facebook gives an example for curl request only.http://developers.facebook.com/docs/opengraph/actions/Thanks,S.Technology used:Asp.net mvc3
