Details of the issue are in this link. I reported this issue, at this time, looks like this is happening because of MongoDB Dependencies.

https://developercommunity.visualstudio.com/content/problem/164184/publish-tools-are-failing-after-upgrade-to-vs-2017.html

Note that after trying everything mentioned there, eventually ended up with the below error. I tried everything for days & nights - reinstalled nuget packages over and over again. The only way to get it to work was to install VS 2017 on my Azure VM and then the error stopped happening.

I went through all the dependencies of the driver, found some documented ones missing - installed them manually - nothing worked.

Very hard to debug this issue and it does not say which file is missing. VS 2017 install fix indicates that the missing dll was probably in the GAC.

Note I even installed .NET 4.7.1 and latest .net core on that VM - even that did not get the below to work
