 _BNuget_ works with Unity Assembly Definitions. An Assembly Definition is a file that logically groups a set of C# script files into one compile unit. Every C# script in a Unity project is grouped into an Assembly Definition. By default, there are a set of [predefined assemblies](https://docs.unity3d.com/Manual/ScriptCompileOrderFolders.html) that capture most C# scripts. However, if an Assembly Definition file is created, then all C# script files in the Assembly Definition's folder and sub folders are part of the Assembly Definition. When Unity compiles the C# code in a project, each Assembly Definition's C# script files are built into individual `.DLL` files and shipped with the Unity game.

 _BNuget_ uses a hierarchical file based configuration system. A configuration asset will define the behavior of _BNuget_ operations for all `.bnuget` files in the sub directories of the configuration. Each `.bnuget` file will be configured by exactly one configuration asset. If there are multiple configuration assets in a `.bnuget` file's parent path, then the closest configuration by file distance will be used. If there is no configuration file anywhere in the parent path of a `.bnuget` file, then that `.bnuget` file will use the default hardcoded configuration.

 Nuget packages can come from a variety of locations. Many packages are located on [nuget.org](https://nuget.org), which is a public repository of (mostly) free packages for the Dotnet environment. However, _BNuget_ can be configured to use packages from additional locations. The Nuget API defines the schema for a Nuget Package Source, and _BNuget_ supports the v3 Nuget API specification.
