Hello i am working on my template web api project.

I just wanna hear any suggestion how to improve this code. I heard that repository pattern is anti pattern so i want to make code without it. Any opinion will be great 😀

Service

public class TemplateService : ITemplateService {     private readonly ContextTemplate context;      public TemplateService(ContextTemplate context)     {         this.context = context;     }      public int AddTemplate(TemplateInput input)     {         var template = new TemplateModel()         {             Name = input.Name,             CreatedDate = DateTime.UtcNow         };          context.TemplateModel.Add(template);         context.SaveChanges();         return template.Id;     }      public int UpdateTemplate(TemplateInput input)     {         var template = GetTemplate(input.Id);         if (template != null)  {             template.Name = input.Name;             template.ModifiedDate = DateTime.UtcNow;             context.Update(template);             context.SaveChanges();         }         return (int)template?.Id;     }      public bool ArchiveTemplate(int templateId)     {         var isArchiveSuccessfull = false;         var template = GetTemplate(templateId);         if (template != null)         {             template.IsArchived = true;             isArchiveSuccessfull = true;             context.Update(template);             context.SaveChanges();         }         return isArchiveSuccessfull;     }      public IEnumerable<TemplateModelDto> GetTemplates()     {         return Mapper.Map<List<TemplateModel>, List<TemplateModelDto>>(this.context.TemplateModel.Where(x=>!x.IsArchived).ToList());     }      public TemplateModel GetTemplate(int templateId)     {         var template = context.TemplateModel.FirstOrDefault(x => x.Id == templateId);         return template;     } 

Controller

 [Route("api/[controller]")]  public class TemplatesController : Controller  {     private readonly ITemplateService templateService;     private readonly ILogger logger;      public TemplatesController(ITemplateService templateService, ILogger<TemplatesController> logger)     {         this.templateService = templateService;         this.logger = logger;     }     // GET api/templates     [HttpGet]     public IEnumerable<TemplateModelDto> Get() => templateService.GetTemplates();      // GET api/templates/5     [HttpGet("{templateId}")]     public TemplateModel GetTemplate(int templateId) =>  templateService.GetTemplate(templateId);      // POST api/templates     [HttpPost]     public int Post([FromBody]TemplateInput input) => templateService.AddTemplate(input);      // PUT api/templates/5     [HttpPut("{templateId}")]     public int Put(int templateId, [FromBody]TemplateInput input) => templateService.UpdateTemplate(input);      // DELETE api/templates/5     [HttpDelete("{templateId}")]     public Boolean ArchiveTemplate(int templateId) => templateService.ArchiveTemplate(templateId); }
