Hi, SingleOrDefault() The SingleOrDefault() method returns a single specific element of a sequence or default value if that element is not found in the sequence. Whenever you use SingleOrDefault, you clearly state that the query should result in at most a single result. FirstOrDefault() The FirstOrDefault() method returns a first specific element of a sequence or default value if that element is not found in the sequence. Whenever FirstOrDefault is used, the query can return any amount of results but you state that you only want the first one.
