Use the Unity Package Manager Client class to manage the packages used in a Project.
Note: You can only call the Client methods in sequence. If you try to add or remove multiple packages at the same time, the outcome is nondeterministic. For example, if you call the Remove method on a package while a Remove operation is already in progress or queued, might overwrite the current operation and only handle the latest Remove operation.
| Add | Adds a package dependency to the Project. This is the equivalent of installing a package. |
| List | Lists the packages the Project depends on. |
| Remove | Removes (uninstalls) a previously added package from the Project. |
| ResetToEditorDefaults | Resets the list of packages installed for this Project to the editor's default configuration. This operation clears all packages added to the Project and keeps only the packages set for the current editor's default configuration. |
| Search | Searches the Unity package registry for the given package. |
| SearchAll | Searches the Unity package registry for all packages compatible with the current Unity version. |
