FSharp.Core version warning (net7.0)

[quentez]

Describe the bug
Following what I suspect to be this change, I now get the following warning after upgrading to version 3.3.0:

[NU1608] Detected package version outside of dependency constraint: FsToolkit.ErrorHandling 3.3.0 requires FSharp.Core (= 4.7.2) but version FSharp.Core 7.0.0 was resolved.

To Reproduce
Steps to reproduce the behavior:

1. Add FsToolkit.ErrorHandling.TaskResult version 3.3.0 to a net7.0 project.
2. Build the project.

Expected behavior
No warning.

• OS: macOS 13.0

Yup, I think there should be >= instead of =

[cmeeren]

Yes, this was >= before, but is now =. For us who have enabled warnings as errors, this precludes updating FsToolkit.ErrorHandling.

Ah paket has changed rules around its version. Lemme see if I can clean it up

[TheAngryByrd]

Opened an issue on paket as it seems they are generating a nuspec file differently fsprojects/Paket#4183

[TheAngryByrd]

I think i'm gonna pull the version from nuget for the moment

[yreynhout]

This happens for net6.0 projects too.

[abelbraaksma]

Fwiw, 3.2.0 does not exhibit this problem, it has the versions as >=. And if I saw it correctly, 3.3 is beta, or did you pull the definitive version already @TheAngryByrd?

[TheAngryByrd]

I already pulled the official version. Please refer the paket issue I filled as that's the root cause.

Do you mean that a new package with unlocked FSharp.Core version won't be published before upstream fixes it? Since the NuGet package is now locked to a fairly old F# version, it may prevent many people from updating until it's fixed. Would be great to have a package released with unlocked version as a quick fix!

Yes, I'm not gonna get into the habit of hand editing nuget packages everytime I need to do deploy and this helps the ecosystem.

[TheAngryByrd]

Just published https://www.nuget.org/packages/FsToolkit.ErrorHandling/3.3.1-beta002#dependencies-body-tab

can you give it a try?

[quentez]

Looking good on my end!

[cmeeren]

Looks good on NuGet! (Assuming that you want to require FSharp.Core 7.0.0 on netstandard2.1.)

[abelbraaksma]

Question: do we really need to force upgrade to F# Core 7.0? On NetStandard 2.1, the lowest denominator with tasks) should probably be used, which is 6.0.2, or 6.0.6 (Result additions).
