Is this still up to date?

[FacticiusVir]

For the most part this is up to date; I'm currently working on a port of Sascha Willem's Vulkan samples that will properly test the remaining methods, though the full API is being generated and should work correctly.

[realvictorprm]

Please bear with me, but what prevents usage of VulkanSharp from Mono?

[FacticiusVir]

If you're asking why I created these bindings, rather than using the VulkanSharp project - I'm not a fan of VulkanSharp's interop layer which has a lot of opportunities for memory leaks. Additionally, the API as a whole uses a lot of short-lived reference-type objects which causes a lot of memory churn & GC pauses, which is a real problem for apps trying maintain a consistent framerate. On an aesthetic note, SharpVk also arranges the API to be more C#-like, with commands invoked from the specific handle (e.g. CommandBuffer.Draw) instead of the parent Instance or Device.

You might also want to look at https://github.com/discosultan/VulkanCore, which is a hand-crafted binding where ours are auto-generated.

[realvictorprm]

I would rather say that it's more Object oriented :) Thanks for this information. I would suggest to add this to the read me or somewhere else too because it wasn't clear to me from the readme.

[realvictorprm]

You said it's auto generated, why isn't than everything auto generated? If so the list would be checked completely wouldn't it?

[FacticiusVir]

To clarify - all the methods listed are generated, but they're checked when I have sample code that proves the generation is correct and shows how they're used. You should be able to use any of these methods from your code if you need them.

[realvictorprm]

Thanks you very much for this information. So we could contribute to this if we help translating the C++ Samples for Vulkan, right? If so I'm going to translate some too.

[FacticiusVir]

That would be great, thanks! There's a Samples projects here - I'd started porting the C++ base classes in response to https://github.com/FacticiusVir/SharpVk-Samples/issues/2 so the TextOverlay project is the priority, but I'd not had time recently to make much progress so any contribution would be very welcome.
