New Post: Window Forms

Hi Linvi

thank you for your reply.

I believe my credentials have been set correctly because the Who Am I correctly returns the name of the account
I have added the .NewGuid() call to all tweet strings.
The second case of tweet which is created, is NOT null after it is used, however after each of the two lines (i.e. the var creation line and the .Publish()) the last exception is

• exceptionInfos {"Operation is not valid due to the current state of the object."} TweetinviCore.Exceptions.ITwitterException {TweetinviLogic.Exceptions.TwitterException}
  

Any ideas?

Edit: that exception is being set on the PublishTweet and on the var tweet = and on the .Publish
