Hi guys,

I am having a problem with providing coordinates to my app in C#.

string access_token = tokens["access_token"];

var client = new FacebookClient(access_token);

client.Post

  ("/me/checkins", new {coordinates=("latitude='51.47', longitude='-3.09'"), place="test", message = "message!"});

when I run the application, I get this error:

(OAuthException - #160) (#160) Invalid coordinates. Coordinates must contain at least latitude, and longitude.

Would you kindly help?

Thanks
