@Gökhan DURMAZ Welcome to Microsoft Q & A Community Forum. AFAIK, it is not possible to assign multiple users to a task in Azure Devops. There is open feedback thread for this under review. Also, kindly note this forum is mainly intended for Azure questions. I would kindly suggest you to post Azure DevOps question here where Azure DevOps experts can assist you effectively for your request.
