Find .NET Core packages in all projects

In a quick aide-memoire for next time I need to use it: here’s a Powershell snippet that will return a list of all unique package names in all .NET Core projects under the current folder:

get-childitem -recurse -filter *.csproj |
  foreach { get-content $_.FullName } |
  select-string -pattern "PackageReference Include=""(.+?)""" |
  % { $_.matches[0].Groups[1].Value } |
  sort-object -unique

Line by line…

• Get all *.csproj in the current and child folders
• Read the content of each one
• Extract every line that matches the specific regex and extract the name of the package
• Grab the package name group
• Sort & filter to unique values

This outputs something like

CommandLineParser
CsvHelper
Microsoft.Extensions.DependencyInjection
Microsoft.Extensions.Logging
Microsoft.Extensions.Logging.Console
