A needed tool that works, more or less. The less part is the persistent problems it continues to have. A big favorite is the inability to implement proper updating because of key signature problems. This has been going on since the beginning... Here again, February 2013, its broekn again. Please fix it. Another issue is that it gets confused and loses track of the libraries its managing. This happens infrequently, thank Buddha, but when it does it screws things up pretty good. It should be advertised as perpetual beta and used with extreme caution on any non-trivial project.
can you please take a look the known issues list here for the fix: http://docs.nuget.org/docs/reference/known-issues#Upgrading_to_latest_NuGet_from_an_older_version_causes_a_signature_verification_error.
