We have some legacy components still running on ESXi 5.5 and we're looking to upgrade to 6.7. The legacy components hook into vCenter and automate VM deployments and install/config. It's not something we could easily port over to vRealize and Ansible (largely because we don't have the employees to do it, rather than because it's impossible -- small company problems). Anyway, the existing software we have is all written in C# and uses the PowerCLI APis. Except for one teenie, tiny little problem: I can't find vmware.vim.dll in the new PowerCLI 10+ installs (the PowerCLI versions for ESXi 6.7+). That DLL only seems to ship with the 6.5 and earlier PowerCLI installs. So...is the C# API just gone for 6.7? I can't find anything on google about where it went.
Nevermind, I found the DLL file. It was hiding in the Powershell modules folder in C:\Users. *phew*.
