[BUG] Propably serialization bug on retrieval GetOrFetchObject.

[tomasfil]

After some testing the issue is ReactiveObject, upon removing inheritation from ReactiveObject, then the cache is running just fine.

[glennawatson]

ReactiveObject has some quirks in regards to serialisation.

[tomasfil]

Almost all my domain object are inheriting ReactiveObject, so forth making it every single one not usable with the Akavache cache...

@glennawatson Any tip how to make this work? It seems like I would need to implement whole new layer for DTOs, that would get cached.
That would be Entity -> DTO -> Domain object

Which doesnt really makes sense, because all of the apps are WPF, accessing database directly via repository pattern on top of Entity framework, so the Entities are our DTOs.

Implementing DTOs would require to make huge infrastructure changes, since some entities are desired and some not to be cached.

The most reasonable thing is to cache normally ReactiveObject, but I am not sure where the issue lies in the first place.

If it was me I would use source generators to generate the dto at compile time so I'm not having to manually generate them all.

There are some serialisation hints in the docs that may help

One thing I can think of causing issues is Akavache uses the binary compiler by default.

I am aware of DTO generators, but for this project it doesnt make sense to map the entity 2 times, it is just excesive.

Binary compiler? Is there way for me to test out this theory? I went through source code briefly, but didnt find out what you mean

[tomasfil]

I am aware of this, i use it for the user preferences and settings, but I wanted to use Akavache for the temporary cache of some objects, that get loaded from db from time to time, but need to be refreshed 30-60 minutes.

I thought that it would be good idea to use Akavache, since it is from ReactiveUI, but it makes little to no sense, that it has problems with the main MVVM framework object of RxUI.

To complement, the issue is there not only on NET 5, but on NET 6 and all latest versions:

Oof, so, it seems like restarting the computer fixed the issue 😄 I will test out tomorrow and close the issue if that is the case
