Issue with partially unload an asset.

Hi @unity_bill

In docs for memory management there is one section about unloading partially unload asset:
https://docs.unity3d.com/Packages/com.unity.addressables@1.2/manual/MemoryManagement.html

This case doesnt work for me. I cant unload only just one asset from memory. Even, Im making mirroring load-unload operation there is still reference to asset (in my case im trying load/unload Sprite). In detailed memory profile i got this ref (see screenshot).

Am I doing something wrong?

Loading two different sprites from same bundle:

Code (CSharp):

1.  
2. Addressables.LoadAssetAsync<Sprite>("Assets/Sprites/A/element_fire.png").Completed += handle =>
3. {
4.       _opCache.Add(handle);
5.       image.sprite = handle.Result;
6. };
7.  
8. Addressables.LoadAssetAsync<Sprite>("Assets/Sprites/B/element_fire_1.png").Completed += handle =>
9. {
10.     image2.sprite = handle.Result;
11. };
12.  

Trying unload only one sprite:

Code (CSharp):

1.  
2.            foreach (var sprite in _opCache)
3.            {
4.                 Addressables.Release(sprite);  
5.             }
6.          
7.             _opCache.Clear();
8.                          
9.             image.sprite = null;
10.  
11.             Resources.UnloadUnusedAssets();
12.  

I found that reference staying inside of LRUCacheAllocationStrategy, as released operation with referenece to asset (m_Result). When I cleared result to null in ProviderOperation.Destroy() everythings works now. Can you please check/confirm this issue and suggest fix for that?

 

Hi, is there any progress on that please?
