### From the Project Panel

Whenever you add a web service to a library project or install a new dependency to your project, either a `.nupkg` file from **Manage Packages** default feeds or a custom library that you've created, the namespace can be imported from the **Project** panel as well.

Simply right-click the dependency or web service in the tree, and select **Import Namespaces**. The namespaces are automatically added to your project, you can check them in the **Imports** panel.

## Removing Namespaces

To remove a namespace, open the Data Manager, navigate to the **Namespaces** panel, then right-click the namespace and select **Delete**.

To remove all the namespaces that are not used anywhere in the current file, select **Remove Unused** > **Imports** in the Studio ribbon.

Note that namespaces can only be removed if they aren't used. For example, you can remove a namespace from the project if the assembly that contains it is no longer referenced by the project.
