Return newly created TFS work item ID using TFS API?

Question

Using the TFS API, I am able to create a TFS item, no problem.

What would be the best way for me to know what the Item ID is for the newly created Item?

Thank you,

George

As soon as you save userStory, the ID field will be populated. You should be able to just return userStory.Id.
