The problem is that I need

This extended version of the PS Script from Danny Tuppeny shows references for both csproj and vcxproj files, and also supports

-Depth - maximum dependency chain length

-Like - prints only dependency chains starting with projects with name -like $Like

-UntilLike - cuts dependency chains on projects with name -like $UntilLike

-Reverse - prints reversed dependency chains ([proj] <- [referencing proj])
