Description

Xamarin.Forms >= 2.3.4 depends Xamarin.Android.Support.* packages >= 23.3, but for MonoAndroid1, it is pinned at exactly 23.3.

Paket always assumes it needs to be exactly 23.3

Repro steps

This paket.dependencies file will fail:

content: none
redirects: on
source https://www.nuget.org/api/v2/

nuget Xamarin.Forms 2.3.4.231
nuget Xamarin.Android.Support.Design 25.4.0.2

Expected behavior

Same as NuGet, both packages must install, as they're compatible

Actual behavior

Paket version 5.96.1
Resolving packages for group Main:
 - Xamarin.Android.Support.Design is pinned to 25.4.0.2

Paket failed with

     Resolved packages:

      - Xamarin.Forms 2.3.4.231 requested package Xamarin.Android.Support.Design: 23.3

     Please try to relax some conditions or resolve the conflict manually (see http://fsprojects.github.io/Paket/nuget-dependencies.html#Use-exactly-this-version-constraint).

Known workarounds

  1. Use NuGet
  2. Don't use Xam.Support > 23.3

Event specifying == doesn't work, with nuget Xamarin.Android.Support.v7.AppCompat == 25.4.0.2:

Conflict detected: - Dependencies file requested package Xamarin.Android.Support.v7.AppCompat: == 25.4.0.2 - Xamarin.Android.Support.Design 25.4.0.2 requested package Xamarin.Android.Support.v7.AppCompat: 25.4.0.2 - Xamarin.Forms 2.3.4.231 requested package Xamarin.Android.Support.v7.AppCompat: 23.3

So I guess you don't want to build for MonoAndroid1? I guess you might be able to filter that with framework restrictions ..

Paket by default/design tries to find a global solution of packages valid to compile for all frameworks. It will not (like Nuget) allow different versions of a single package.

Paket tells you that such a solution doesn't exist for your specified dependencies...

So you can either change your version or tell paket you don't care about monoandroid framework

== on the other hand should work as well if applied to the correct packages, but you basically will have an unsound resolution in that case.

Ah, so simple. Works :)

nuget Xamarin.Forms 2.3.4.231 framework: MonoAndroid7.0
nuget Xamarin.Android.Support.Design == 25.4.0.2
nuget Xamarin.Android.Support.v7.AppCompat == 25.4.0.2

to make it very clear: This is abuse of the concept of a package. I wished MS would be more careful...
