ExternalCode is a ReSharper plugin that adds support for source files that are not part of a project.

This plugin allows adding source files to ReSharper's code analysis by specifying folder paths. This is particularly helpful in situations where code is included at build time but not necessarily available during development, such as code generation.

NOTE: Exclusions specified in Code Inspection | Generated Code still apply to external code.

You can install directly using ReSharper's extension manager.

From menu bar, select ReSharper | Manage Extensions. In the left pane, select Online, search for "externalcode", then click Install in the results.

ReSharper supports the concept of setting layers where settings can be personal, team-shared, or this computer. By default, settings are this computer and apply to any project loaded on the local machine. You will generally want to use team-shared project settings for this plugin. This allows project-specific settings while allowing the settings to be added to source control and shared with other users of that project.

1. On the main menu, choose ReSharper | Manage Options. The Settings Layers dialog box opens.

2. Select the Solution team-shared layer and click Add Layer, then click Create Settings File. The Save As dialog box opens.

3. Set the settings file name and path and click Save. Save the settings file in project folder and name it the same as the project file and append .DotSettings extension.
   For example, the project MySolution\MyProject.csproj has its settings file named MySolution\MyProject.csproj.DotSettings.

1. On the main menu, choose ReSharper | Manage Options. The Settings Layers dialog box opens.

2. In the Settings Layers dialog, select a layer to be edited then click Edit Layer. The Options dialog opens.

3. In the left pane, click Code Inspection | Include External Sources.

4. In the right pane, add/edit/remove paths that contain external source files.

5. Click Save to save the changes and close the dialog.
   Changes do not take affect until project is reloaded.

Paths may be relative or absolute to files or directories. Relative paths are relative to the directory containing the project.
