Yes, I check after using break point, I am getting Null Reference Exception, and you are absolutely right, that problem is in _localendpoint.ConferenceServices. Problem is _localendpoint OBJECT is empty,I am not getting how to pass values to it.
You gave enough links, I will try to see what i am doing wrong here.

Hello, I found this useful, because reading from this, at least i am able to understand and write some code. but issue is not resolved yet

private void button1_Click(object sender, EventArgs e)
{

ConferenceScheduleInformation CSI = new ConferenceScheduleInformation();

CSI.AccessLevel = ConferenceAccessLevel.Everyone;
CSI.AutomaticLeaderAssignment = AutomaticLeaderAssignment.Everyone;
CSI.ConferenceId = "Whatever";
CSI.Description = "Test Conference";
CSI.Subject = "Testing_Subject";
CSI.Mcus.Add(new ConferenceMcuInformation(McuType.AudioVideo));

try
{
_localendpoint.ConferenceServices.BeginScheduleConference(CSI,
ar =>
{
try
{
Conference newConference = _localendpoint.ConferenceServices.EndScheduleConference(ar);
//DoSomethingWithTheConference(newConference);
}
catch (RealTimeException ex)
{
Console.WriteLine(ex);
}
},
null);
}
catch (InvalidOperationException ex)
{
Console.WriteLine(ex);
}

}

Hello Sir, i am having a doubt, you can see my whole share button click event handler method i posted below. In that what i think is, i am giving posttaskasync wrong path. I am talking about this line
await fb.PostTaskAsync(String.Format("/me/{0}:eat", Constants.FacebookAppGraphAction), new { meal = Video_Id, tags = Video_Id, place = Video_Id });
because before getting this bool object exception i was getting
(OAuthException - #2500) Unknown Path components:/namespacebyfacebook

now when i made changes to this line then i got rid of this exception but started getting new above exception. I hope you got what i am trying to explain.

AND using break point at e.Getresultdata i am getting
e(facebook.facebookApiEventargs) 
and in that
base
Non-public members
and in non-public members
result | true

Hello Sir, i exactly tried this before. first of all this is my whole event handler method for share button 
 
async private void PostActionToFBHandler(object sender, EventArgs evtArgs) 
{ 
NavigationContext.QueryString.TryGetValue("Video_Id", out Video_Id); 
 
FacebookSession session; 
 
string message = String.Empty; 
try 
{ 
session = await App.FacebookSessionClient.LoginAsync("publish_stream"); 
} 
catch (InvalidOperationException e) 
{ 
message = "Login failed! Exception details: " + e.Message; 
MessageBox.Show(message); 
return; 
} 
 
FacebookClient fb = new FacebookClient(App.AccessToken); 
 
fb.PostCompleted += (o, e) => 
{ 
if (e.Error != null) 
{ 
Dispatcher.BeginInvoke(() => MessageBox.Show(e.Error.Message)); 
return; 
} 
 
var result = (Dictionary<string, object="">)e.GetResultData(); 
 
Dispatcher.BeginInvoke(() => 
{ 
MessageBox.Show("Posted Open Graph Action, id: " + (string)result["id"], "Result", MessageBoxButton.OK); 
}); 
}; 
 
await fb.PostTaskAsync(String.Format("/me/{0}:eat", Constants.FacebookAppGraphAction), new { meal = Video_Id, tags = Video_Id, place = Video_Id }); 
} 
 
Sir, i already tried what you said. But i am using lambda expression so i am exception when i change variable result to bool type these are the exceptions 
 
Error 1 Cannot apply indexing with [] to an expression of type 'bool' 
Error 2 Cannot convert lambda expression to type 'System.Delegate' because it is not a delegate type 
Error 3 Cannot implicitly convert type 'object' to 'bool'. An explicit conversion exists (are you missing a cast?)

Member 10801309 15-May-14 9:44am View

sir, i think i am doing something wrong after this method call, exactly after this method call takes place i am calling this

await fb.PostTaskAsync(String.Format("/me/{0}:eat", Constants.FacebookAppGraphAction), new { meal = Video_Id, tags = Video_Id, place = Video_Id });

I am definitely making some mistake, while making object and the path i am giving to it.
Sir, i will see to it what is wrong.

and thank you for your quick reply.

Member 10801309 15-May-14 9:05am View

sir, then what should i do, i changed that way also and checked i am getting same exception. i got your point, but what should i do if object o is of value type bool? then how should i get it? i did different way, but its not working.

Member 10801309 15-May-14 8:49am View

It is showing in additional information Unable to cast object of type 'System.Boolean' to type 'System.Collections.Generic.IDictionary

How to solve this exception i am not getting it.

Member 10801309 15-May-14 8:26am View

I am getting bool type data in 'e' which is showing 'TRUE'. I checked that by using break point.

and because of this exception i am not able to post to facebook wall.

Member 10801309 8-May-14 0:25am View

Hello Sir, Any help would be really appreciated. Actually i am not getting a single example, how to do it. I am not even sure if it is possible to do so in WP8 or not, The same application is developed by our android and ios team, and they did it very easily, They are able to play that sound file once on application start up with splash screen.

Member 10801309 7-May-14 9:11am View

Sir, i am using that code to play audio file. But i am able to use it in mainpage constructor, now problem is every time i am coming back to mainpage it is playing that sound. But i want to play it only once with splash screen that's it. sir, I hope you are getting what i am trying to explain.

Member 10801309 7-May-14 9:07am View

Sir, i updated my question, and tried as much as possible to explain. I just want to play a small .wav file once on application start up, when splash screen in application comes up. Thank you.
