UpdateTaskWithLocalizedValue method is not updating the task details in SharePoint.

Hi All,

I am working on a solution that updates the Project task details that are created in SharePoint for a user. I am using the CSOM for same. Below is the code snippet that i am using for update.

LocationOrientedUserOrderedSession uos = osm.CreateLocationOrientedSession();
uos.UpdateTaskWithLocalizedValue(myNewTask.Id, WritableTaskField.Description, “New Description”);

As per my expectation UpdateTaskWithLocalizedValue method should update the description however method is neither giving any error nor updating the task description.

Any suggestion here?
