问题 I'm working on a .NET Core project with a friend and we're splitting the work as we see best.

I've decided on MongoDB, and I've found this page which seems to suggest that the following code will configure our project somehow to use the library. Selecting .NET Core and Nuget (both of which I've installed locally and on our server), I get the following code which seems to be
