I try upgrading my solution to nuget but I have encountered many and many problems in every operation on reference (update many times tends to make it impossible to use some packages and find non way to remove it or make it work, our reverse proxy block some installation, use svn to align the PC development tends to create references to non-existent, install specific version of a library in difficult, and many more)
in short, a disaster compared to the old copy paste of some files made only when I really need to update a library
So I revert all to the old way (manual download of dll) and all work fine except for ajax control toolkit and and postsharp.
There is a way to extract dll from nuget packages to install them with a simply copy/paste?
I have, in the past, created a dummy project just to use NuGet to add the required package containing the specific DLLs I want. Then it exists on my machine and I can copy/paste/whatever the DLL as I see fit into the real project.
