New Post: Search doesn't work properly under WCF

Hello,

Maybe this is a strange requirement but I'm running into a bug of some sort when trying to run Tweetinvi in a self hosted WCF application. Running the SearchJson version of SearchTweets once or twice will work, but the second or third time will always give an exception of the type below. I cannot trigger it using the same code in a regular console app. It seems to happen more often with the debugger attached? I have pasted my code below.

If you are interested in looking at this but don't have WCF experience I could send you a sample solution.

An exception of type 'System.NullReferenceException' occurred in Tweetinvi.dll but was not handled in user code

System.NullReferenceException was unhandled by user code
HResult=-2147467261
Message=Object reference not set to an instance of an object.
Source=Tweetinvi
StackTrace:

        [OperationContract]
        void Backfill();
    }
    
    class Backfiller: IBackfill
    {
        public void Backfill()
        {
            Tweetinvi.TwitterCredentials.SetCredentials("your", "credentials", "go", "here");
            var tweets = Tweetinvi.Json.SearchJson.SearchTweets("test");
        }
    }
}
