Update to .NET7

[Tim Forkmann]

Its this time of the year...

@dustinmoris Do you mind releasing a new Giraffe version?
I would the try to upgrade Saturn.

Thanks,

Tim

[Tim Forkmann]

Any news on that? Cheers, Tim

I thought there was no need to update the tfm if there was no binary breaking changes in dependencies and we weren't taking advantage of new APIs?

[Dustin Moris Gorski]

That's a good question. I don't think it needs updating since none of the .NET 7 changes affect Giraffe but I've posted a question to see if someone knows.
