Package manager for Unity, which one and how to use it?

Question

Mono

I tried to figure out how to install packages in a Unity project, but since I don’t know the ecosystem, it didn’t work out. I will say right away that the following operations were performed through the IDE Rider.
I know that NuGet exists and I actually saw it as an integrated option in Rider. Tried to install two packages. As a result, I saw that the manager installs in the root of the project rootProject/packages/*. After, I created a local config for NuGet and indicated that the packages should be downloaded in rootProject/Assets/Packages. After I noticed that the downloaded packages contain dll, instead csof scripts. Where to dig?

Answer 1

First, you have to come to terms with the idea that there are no packages in the sharp, but libraries (*.dll), which, most often, cannot be viewed and edited.
Secondly, the unity is a completely different story. Either download *.unitypackage (for example, from the same asset store), which encapsulates all kinds of assets, or connect those same libraries ( be sure to look at the corresponding section of the documentation ).
It is also important to know that the old sharp is used in the unit (like 4).

Answer 2

Unity has its own format - Unitypackage. Which is used for all plugins, and incl. for what lies on the AssetStore (which is to some extent a package manager).
