JetBrains Rider 2021.3 Help

Explorer window

The Solution explorer lets you take a look at your solution from various viewpoints and perform different tasks such as creating new items (directories, files, classes, and so on), opening files in the editor, navigating to the necessary code fragments, and more.

Most of the functions in this tool window are accessed as context menu commands in the content pane and via associated shortcuts.

Also, the view contains the Scratches and Consoles folder that lets you manage created scratch files, database consoles, and extension scripts.

Views

The tool window has several views:

  • Solution view, which contains the solution node with an organized logical view of projects and project items in the current solution, as defined in its .sln file.

  • FileSystem view, which shows you all files and subdirectories starting from the directory where the current solution file is located.

  • Unity view, which provides an organized view of all assets in a Unity project (you see exactly the same project tree as in the Unity editor). This view is only available for Unity projects.

  • Assembly Explorer view, which lets you open and explore compiled assemblies.

To switch between views, press Alt+Right/Alt+Left or select the desired view from the list on the title bar.

JetBrains Rider: choosing a view in the Solution Explorer

To configure a view, use the corresponding options in the title bar context menu. The necessary options can also be accessed by clicking Settings on the title bar.

Search the Explorer window

There are two ways to search items in the Explorer window: speed search and full search.

Speed search works in all views of the window — start typing when the application focus is in the Explorer window and JetBrains Rider will highlight all items that match your query in the opened nodes.

JetBrains Rider: Speed search in the Explorer window

Full search works in the Solution and File System views — press Ctrl+F or click Find Icons actions find on the toolbar and start typing the search query. If there are matching items, JetBrains Rider will expand the tree at the first match and highlight it.

You can then press F3 and Shift+F3 or click the arrow buttons on the search panel to navigate between the matches.

JetBrains Rider: Full search in the Explorer window

In the Solution view, you can optionally click Search Settings Icons general gear plain on the search panel and choose to include dependencies (referenced assemblies, imports, NuGet packages, and so on) in the search.

Preview files

There are two ways to preview files without opening each one in a separate tab:

  • Use the file preview popup — select a file in the Solution explorer and press Space.

  • Enable the preview tab — click the Show Options Menu button and select Enable Preview Tab.

Show file size and modification timestamp

The Solution Explorer allows you to see the size and modification timestamp for the files in the solution tree. To display this information, select View | Appearance | Details in Tree Views from the main menu.

Show tree indent guides

In the Solution Explorer, you can display vertical lines that mark indent levels and help you better understand the hierarchy of the components in your solution. To display these lines, enable Show tree indent guides on the Appearance and Behavior | Appearance page of the IDE settings Ctrl+Alt+S.

Toolbar buttons

Show all files Show All Files

By default, JetBrains Rider only displays projects, files and references that are included in the current solution.

You can use the Show All Files option to additionally display all subdirectories and files that are located on the file system under the solution directory. For your convenience, those items are shown in yellow. If non-solution items are not indexed by JetBrains Rider, meaning that you cannot use, for example, Ctrl+Shift+F to search in those files, these items are marked with the no index label. External items in the current solution are marked as attached.
