Latest paket, I have a dependencies file which I have reduced to: -

source https://nuget.org/api/v2
nuget Microsoft.ApplicationInsights.WindowsServer = 1.2.3

This does not work, although (as far as I can see) it should.

Resolving packages for group Main:
 - Microsoft.ApplicationInsights.WindowsServer is pinned to 1.2.3
 - Microsoft.ApplicationInsights 1.2.3
 - Microsoft.ApplicationInsights.DependencyCollector 2.0.0
 - Microsoft.ApplicationInsights.PerfCounterCollector 2.0.0
 - Microsoft.ApplicationInsights.WindowsServer.TelemetryChannel 2.0.0
 - Microsoft.Diagnostics.Tracing.EventSource.Redist 1.1.28
 - Microsoft.ApplicationInsights.PerfCounterCollector 1.2.3
 - Microsoft.ApplicationInsights.DependencyCollector 1.2.3
Paket failed with:
        There was a version conflict during package resolution.
  Resolved packages:
   - Microsoft.ApplicationInsights 1.2.3
   - Microsoft.ApplicationInsights.DependencyCollector 1.2.3
   - Microsoft.ApplicationInsights.PerfCounterCollector 1.2.3
   - Microsoft.ApplicationInsights.WindowsServer 1.2.3
   - Microsoft.ApplicationInsights.WindowsServer.TelemetryChannel 2.0.0
  Could not resolve package Microsoft.ApplicationInsights:
   - Microsoft.ApplicationInsights.DependencyCollector 2.0.0 requested: 2.0.0
   - Microsoft.ApplicationInsights.PerfCounterCollector 1.2.3 requested: 1.2.3
   - Microsoft.ApplicationInsights.WindowsServer 1.2.3 requested: 1.2.3

  Please try to relax some conditions.

It seems to be pulling in version 2.0 dependencies for some reason...

According to nuget.org, Microsoft.ApplicationInsights.WindowsServer v1.2.3 requires = 1.2.3 of Microsoft.ApplicationInsights and >= 1.2.3 for it's other dependencies. That's why Paket tries to get v2.0.0 of Microsoft.ApplicationInsights.*.

You could use strategy: min, to emulate NuGet's behavior of downloading the oldest compatible version. This should get v1.2.3 of every package, which Microsoft.ApplicationInsights.WindowsServer depends on.

I believe strategy:min vs max should not result in conflict vs. non-conflict since it only changes order. I'll take a deeper look

I'm pretty sure this is a bug, but not sure where exactly yet

@mrinaldi

It has something to do with this optimization:

match !state with
| Resolution.Conflict(_,_,stillOpen,_,_) 
    when stillOpen |> Set.exists (fun r -> r = currentRequirement || r.Graph |> List.contains currentRequirement) |> not ->
        forceBreak := true
| _ -> ()

If I comment this block out then it finds a resolution.

I think 28d9b82#diff-781e85b03afcc7c6cedfbd46e3d3b607R430 solves it.

Yeah works now! Interestingly I still get up to 2.x for some of the transitive dependencies - is there a way to stop this aside from adding those manually into the .dependencies file?

Yes now you can try to change the strategy to min.

You are receiving this because you modified the open/close state.

Hmmm. Yes that works as well although not quite what I'm thinking, which is more "don't go above 'major' version of transitive dependencies".

  • A = 1.2.3
  • A depends on B >= 1.2.3
  • I don't want B to ever go >= 2.0

I guess this is more about the package author of A (not specifying deps version boundaries tightly enough) than paket though, right?

yes that is something that can't be really expressed in nuget
