Fleece should not include LinqBridge for a .NET 4.5 project

[ctaggart]

When installing Fleece in a .NET 4.5 project, LinqBridge should not show up as dependency. This is related to #140. //cc @mausch

The test project to reproduce is here:
https://github.com/ctaggart/Paket09x/commits/master

https://www.nuget.org/packages/ReadOnlyCollectionExtensions/

With it added as a dependency, you get warnings like this:

because it includes implementations of System.Action and System.Func

/cc @cdrnet @agross

I think this one might be solvable. The assumption is: we only reference one version of LinqBridge.
We can't have LinqBridge 1 for framework A and LinqBridge 1.1 for framework B.

Then we need to do the following:

• add framework restriction to lock file
• parse framework restriction from lock file
• use this info in install model

[agross]

@forki As far as I understand it, that's reasonable.

[ctaggart]

I upgraded us to 0.14.3 and this is still an issue.

[forki]

sorry, but we're making only very slow progress here.

But the resolver and the lock file understands this now.

==> The last part is extending the install model.

[forki]

It seems 0.15 is working for https://github.com/ctaggart/Paket09x/commits/master

[ctaggart]

Yes, LinqBridge is gone. However, FSharp.Data.SqlClient is too. I'll create another ticket. I updated the repo.

I'm just getting started with Paket and having this problem in version 0.25.1.0. The problematic package for me is https://www.nuget.org/packages/Cassette/ , it's choking on the Iesi.Collections dependency even though it's a .NET 4.5 project.

I only ran paket convert-from-nuget, then fixed a couple minor issues with incorrectly named packages, then paket install, do I need to do anything else?

@ctaggart have you opened another issue about this? I can't seem to find it.

[forki]

What's the concrete error?
What's your dependencies file?

The exact error is (when running paket install):

  Can't resolve:
    - Iesi.Collections <  4.0
       - from Cassette 2.4.2
 Please try to relax some conditions.

This project has a huge list of dependencies, but the problem seems to be that NHibernate 4.0.2.4000 requires Iesi.Collections (≥ 4.0 && < 5.0) and this conflicts with Cassette's requirement of Iesi.Collections (< 4.0) (which only applies to .NET 3.5 and therefore should be ignored for this particular project).

Let me know if that's enough or you want a more precise repro.

Cheers

[forki]

I now understand the issue. I'll try to come up with a solution.

[forki]

as a workaround add

nuget Iesi.Collections == 4.0.1.4000

to your dependencies file. This will force the version.

[mausch]

Thanks, that workaround did the trick. I just have to be careful with paket simplify until this is fixed, as it removes that versioning constraint from the dependencies file (or is that a separate issue?)

[forki]

Yes. I'm working on a better solution. Internally we already have
everything to say: just don't care about net35. But this is not part of the
dependencies file yet
