  Hi @mahendra,

  Could you also share your Entity definition and the code you update this entity ?

  Thanks,

  Here is my Entity Class, CacheItem and Cahe Class...

  `[Table("InvProductGroup")]
  public class ProductGroup : MCFullAuditedEntity
  {
      [Column("ProductGroupKey")]
      [Key, DatabaseGenerated(DatabaseGeneratedOption.None)]
      [MaxLength(BaseEntityConsts.MaxKeyLength)]
      public override string Id { get; set; }
  
      [Column("Id")]
      [Required]
      [MaxLength(BaseEntityConsts.MaxEntityIDLength)]
      public virtual string EntityId { get; set; }
  
      [MaxLength(BaseEntityConsts.MaxDescriptionLength)]
      public virtual string Description { get; set; }
  
      
  }
  
  [AutoMapFrom(typeof(ProductGroup))]
  public class ProductGroupCacheItem
  {
      public const string CacheName = "ProductGroup";
      public string EntityId { get; set; }
      public string Description { get; set; }
      
  }
  
  
  public class ProductGroupCache: MustHaveTenantEntityCache<ProductGroup, ProductGroupCacheItem, string>, ITransientDependency
  {
      public ProductGroupCache(ICacheManager cacheManager, IUnitOfWorkManager unitOfWorkManager, IRepository<ProductGroup, string> repository)
      : base(cacheManager, unitOfWorkManager, repository)
      {
      }
  
      
  }`
  
  
  Now in the appService, when I try to get a productGroup having id - 10000000000001 using below code
  
  `var abc = _cacheManager
              .GetCache(ProductGroupCacheItem.CacheName)
              .Get("10000000000001", ()=> someMethod());`
  
  
  it goes to someMethod (below)...which is fine and then in the subsequent call, it does not go into someMethod...which is also fine.    
              
   `private async Task<ProductGroupDto> someMethod() 
      {
          return ObjectMapper.Map<ProductGroupDto>(await _productGroupRepository.FirstOrDefaultAsync("10000000000001"));
      }`
      
      
  

  But when I update the productGroup having id 10000000000001, it updates the productGroup using following code

  `ProductGroup productGroup = await _productGroupRepository.GetAsync(createOrUpdateProductGroupDto.Id); ..... .....

  ObjectMapper.Map(createOrUpdateProductGroupDto, productGroup); await _productGroupRepository.UpdateAsync(productGroup);`

  After the above update, when I try to fetch the productGroup 10000000000001 again, I am expecting the someMethod function to be called as it should invalidate the cache, but it does not....

  Hi @mahendra,

  I tried to reproduce this problem but your code has some problems. ProductGroup doesn't have TenantId field but it must implement IMustHaveTenant interface.

  Could you share classes below without removing anything ?

  1. ProductGroup
  2. MCFullAuditedEntity
  3. ProductGroupCache
  4. and the AppService class
