If you should happen to see this error when calling Users.GetInfo() it's because facebook changed something in the way their hs_info is passed down and the C# API is not expecting nullable values.

Here is the fix:

recompile the binaries from source with the following members and their referencing properties set to set to int?

These are members of > Facebook.Schema.hs_info

private int? grad_yearField;
private int? hs1_idField;
private int? hs2_idField;

If you don't have the capability or need to get your site running ASAP.. i've attached the binaries with this change already compiled in.

When authenticating an application, you will received this error.

WORKAROUND:
Turn off the new dialog in your application settings in Facebook (Developer App -> Your App -> Settings -> Migrations -> "New Data Permissions" -> Disabled

NOTE the WORKAROUND WILL STOP WORKING JUNE 1, 2010.. Code needs to be fixed before then.

I found that the API support for previous API providers is also down.

I have replaced the API with new API from computerBeacon.net http://computerbeacon.net/ Now Facebook integration to my app is working fine.

Same issue here.

Did Facebook changed anything?

If somethings do not work anymore with facebook, my rule is: just wait for one week and if it still does not work, then start worrying.

Unfortunately, this issues now is aout 5 days and I'm starting to get worried.

Hope someone can help us out of this misery.
Don't have the time to convert my running project to the C# SDK. :-/

akole_vaibhav — Fri, 20 Jul 2012 12:07:45 GMT

My app is on production server and stopped unexpectedly...

connectSession.IsConnected() is always returning false.

The code snippet is as follow,

aspx page:

</script>
<fb:login-button perms="publish_stream, email" onlogin='window.location="FacebookSocialMediaInterPage.aspx"'>

</fb:login-button>
<script type="text/javascript">

FB.init('<%=ConfigurationManager.AppSettings["FacebookAPI"] %>', "xd_receiver.htm", { "ifUserConnected": "AfterFBLogin.aspx" });

</script>

AfterFBLogin.aspx.cs Page:

protected void Page_Load(object sender, EventArgs e)

{

Facebook.Session.ConnectSession connectSession connectSession = new Facebook.Session.ConnectSession(<FacebookAppKey>, <FacebookAppSecret>);

connectSession.Login();

if (connectSession.IsConnected()) //THIS ALWAYS RETURNING FALSE

{

//My business logic is here...

}

Thanks in advance.

New Post: Logout in desktop application

ondrej — Thu, 28 Jun 2012 20:47:10 GMT

I'am developing desktop application in Windows Forms using this toolkit. I need to add simple functionality which allow various users to login to Facebook services.

I tried to use Facebook.Winforms.Components.FacebookService.LogOff() and also Facebook.Winforms.Components.FacebookService.Application.Session.Logout() but neither of this methods does not work. Disposing FacebookService component does not work too. Calling ConnectToFacebook method second time does not display login window as I was expecting.

I found lot of posts discussing this issue here, but not single one was usefull.

New Post: Facebook Developer Toolkit :: facebook does not exist in the current context

harinarayananvp — Thu, 17 May 2012 04:01:34 GMT

I am using facebook developer toolkit. I have added reference to facebook.dll and facebook.winforms.dll. Also added Facebook.winforms.dll to toolbox. Please see the code below.

        private void btnLogin_Click(object sender, EventArgs e)
        {
            facebookService1.ConnectToFacebook();

try
{
facebookService1.GetExtendedPermission(facebook.Types.Enums.  Extended_Permissions.status_update);
}
catch (Exception exception)
{
MessageBox.Show(this, exception.Message, "Error");
}

        }

private void btnShare_Click(object sender, EventArgs e)
        {
            String status = txtStatus.Text;
Boolean updated = facebookService1.API.users.setStatus(status);
if (updated)
{
txtStatus.Text = "";
}
        }
    }

I am getting 3 compilation errors.

The name facebook does not exist in the current context.

2.Facebook.Winforms.Components.FaceBookService does not contain a definition for GetExtendedPermission.

3.Facebook.Winforms.Components.FaceBookService does not contain a definition for API.

Why this happens?..No clue about it..Any ideas? Thanks
