  hi

  Can you try to switch the current tenant?

  using (CurrentTenant.Change(tenantId))
  {
      //IDistributedCache<IdentityServer4.Models.Client> Cache
  }

  Hi maliming,

  Thanks for the reply. The situation is:

  using (CurrentTenant.Change(null))
  {
      // GetAsync works on host! It gets cached item from host.
      var cachedClient = await _clientCache.GetAsync(identityClient.ClientId);
  
      cachedClient.Enabled = false;
  
      // But SetAsync does not work on host! It adds a new cached item under tenant folder on redis.
      // Instead of overwriting the item on host folder.
      await _clientCache.SetAsync(identityClient.ClientId, cachedClient, new DistributedCacheEntryOptions
      {
          AbsoluteExpirationRelativeToNow = _identityServerOptions.Caching.ClientStoreExpiration
      },
      considerUow: true);
  }

  Can you try considerUow: false

  Yeap. When considerUow: false, it works!

  What is the reason of this behavior? Should I give up on considerUow? But I need it, because I execute this cache update together with some database operation .

  hi

  You can create a new unit of work.

  
  using (CurrentTenant.Change(null))
  {
      using (var uow = _unitOfWorkManager.Begin(
          requiresNew: true
      ))
      {
          // GetAsync works on host! It gets cached item from host.
          var cachedClient = await _clientCache.GetAsync(identityClient.ClientId);
      
          cachedClient.Enabled = false;
      
          // But SetAsync does not work on host! It adds a new cached item under tenant folder on redis.
          // Instead of overwriting the item on host folder.
          await _clientCache.SetAsync(identityClient.ClientId, cachedClient, new DistributedCacheEntryOptions
          {
              AbsoluteExpirationRelativeToNow = _identityServerOptions.Caching.ClientStoreExpiration
          },
          considerUow: true);
              
          await uow.CompleteAsync();
      }
  }
