Using a custom NUGET package

I have a library class that I've turned into a NUGET package (or created a package from).I am hosting it on a shared drive and managed to get it to show up in the package manager (and also install it). But after that I can't seem to find a way to actually use it in code.

I thought I could just use the name space that the original code is using like this:

using CompanyName.WriteAssistant

Or just do using CompanyName and then var test = WriteAssistant.Write(someObject), but neither seem to work.

I have also noticed that the contents of the package, after being downloaded to the project where I want to use it, is literally just the entire solution folder of the original project, whereas most packages seem to be much smaller with just a nupckg file.

Here is my nuspec:
