The partnership with FC Carolina Alliance Youth Soccer Club ended in 2017. This conclusion is based on the information found in the search results, specifically from the page titled "50th Anniversary All Star Team - North Carolina FC Youth" which states that in 2017, the organization rebranded to “North Carolina FC Youth” (i.e., NCFC Youth), when CASL, TFCA, and the North Carolina Football Club collaborated to pool their resources. This rebranding marked the end of the partnership with FC Carolina Alliance. Source
