'paket add --interactive' does not do interactive adding

[reijerh]

Description

(Tested in 4.8, net5.0, net6.0)

Using paket add --interactive doesn't do what it should; instead of adding the specified package interactively, it justs adds the package to the first found project.

add --interactive is my goto command for adding a package to multiple/all projects in a large solution.

Repro steps

mkdir paket-add-repro
cd paket-add-repro

dotnet new sln -n repro
dotnet new console -f net5.0 -n proj1
dotnet new classlib -f net5.0 -n proj2
dotnet sln add proj1
dotnet sln add proj2

dotnet new tool-manifest
dotnet tool install paket
dotnet tool restore

dotnet paket init
dotnet paket add Newtonsoft.Json --interactive
dotnet paket install
dotnet paket find-refs Newtonsoft.Json

Expected behavior

For every found project, Paket asks me if I want to add the specified reference to it.

Actual behavior

Paket adds the package to the first found project. Note that it also does this without the --interactive flag, which is not what the docs say it should do:

By default packages are only added to the solution directory, but not on any of its projects. It's possible to add the package to a specific project

Last bit of console output:

Known workarounds

E.g: Powershell: (Get-ChildItem -Filter *.*sproj -Recurse).FullName | Sort length -Descending | Foreach {.\.paket\paket.exe add System.Diagnostics.DiagnosticSource --project $_}
