I tried the following:
this install version 220.127.116.11 of TestVersion
now I create a new version of TestVersion (18.104.22.168)
installs version 22.214.171.124 of TestVersion
but when I look at the packages directory of my solution, TestVersion.126.96.36.199 folder still exists (although no other packages depend on this and no projects have the older version installed).
Shouldn't it remove the folder TestVersion.188.8.131.52 or is there a good reason for not doing so?
Secondly, Project A has a reference to Project B
TestVersion 184.108.40.206 is installed in A
TestVersion 220.127.116.11 is installed in B
It does not update reference in Project A, is there a way to make all projects automatically reference 18.104.22.168?
