Will this project support .NET 8 (LTS) once its released? #1616

No issue, just a question. Will this project support .NET 8 (LTS) once its released?

shimat commented 8 months ago

Currently OpenCvSharp is provided as an assembly for .NET 6, which should also work as .NET 8. I think it will be some time before OpenCvSharp.dll will be built as TargetFramework=net8 .

hedronn commented 8 months ago

Assuming there are no breaking changes porting .net6 version to .net8 (which i doubt) it should be fairly easy to simply reference the new framework, plus the project would benefit from the massive performance improvements from version 6 to 8.

Happy to assist in the investigation

How will this affect consumers who use older .NET versions in their product and want the latest OpenCV features?

LostBeard commented 8 months ago

@rhalaly Nuget packages can have multiple framework targets. .Net 7 or .Net 8 targets can be added without losing .Net 6 support. If that were to be the route taken, it would not affect consumers who use older .Net versions at all. Multitargeting in a project as large as this one may not be easy though, and could be a real pain in the rear.

If he simply switched to .Net 8 as the target framework the change would be easier but then, as you stated, people still using older frameworks would not be able to use it.

The current .Net 6 target works in .Net 7 and 8.

That is probably why @shimat wrote

Didn't know it can support multiple .NET versions at once (I know it can support several versions between frameworks, for example .NET and .NET Framework)

Thanks!

Not too long I hope, as we also need to consider the lifecycle of .NET frameworks, below is the Microsoft page link to the roadmap for support of .NET releases.

Note: .NET 6 (LTS) support ends November 12, 2024
