- Memory cache implementation for .Net core

public class CachePocRepository : ICachedEmployeeRepository
    {
        private readonly IEmployeeRepository _employeeRepository;
        private readonly IMemoryCache _memoryCache;

        public CachePocRepository(
            IEmployeeRepository employeeRepository,
            IMemoryCache memoryCache)
        {
            _employeeRepository = employeeRepository;
            _memoryCache = memoryCache;
        }

        public async Task GetEmployeeDetailsId(string employeeId)
        {
            _memoryCache.TryGetValue(employeeId, out Employee employee);

            if (employee != null)
            {
                return employee;
            }

            employee = await _employeeRepository.GetEmployeeDetailsId(employeeId);
            
            _memoryCache.Set(employeeId,
                employee,
                new MemoryCacheEntryOptions()
                {
                    AbsoluteExpiration = DateTimeOffset.UtcNow.AddDays(7),
                });

            return employee;

        }
