Unable to install package with stable version but prerelease dependencies

[skofman1]

Repro steps:

1. Create a package with prerelease dependencies using project.json and dotnet pack
2. Place the package in a folder and configure VS to use this folder as a local repository
3. Create a project with packages.config. Using package manager console/UI add the package to the project.

Error (for example):
Unable to find a version of 'NuGet.Protocol.Core.v3' that is compatible with 'NuGet.Client.Staging 1.0.0 constraint: NuGet.Protocol.Core.v3 (>= 3.5.0-beta-final)'.

sounds like a bug in dotnet pack. I think we shouldn't let you build a "final" version of a package if it has prerelease dependencies.

This is fixed for PackageReference. We should determine if we want to fix this for packages.config, or leave it as is.

@emgarten What needs to be added to PackageReference to get this to work?

@nicbavetta with PackageReference it works by default. To find out more on converting take a look at https://blog.nuget.org/20170316/NuGet-now-fully-integrated-into-MSBuild.html
