JetBrains Rider 2020.2 Help

Explorer window

This tool window lets you look at your solution from various viewpoints and perform the tasks such as creating new items (directories, files, classes, and so on), opening files in the editor, navigating to the code fragment of interest, 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 provides you with the following views:

JetBrains Rider choosing a view in the Explorer window
  • 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.

  • Scratches view, which lets you manage your scratch files and database consoles.

The necessary view is selected from the list in the left-hand part of the title bar or, if the views are represented by tabs, by clicking the corresponding tab.

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.

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 Settings/Preferences Ctrl+Alt+S.

Description

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.

AddAlt+Insert Use this command to create a new item (directory, file, or class) within the selected one. (solution or directory). JetBrains Rider will suggest available file templates for creating new files.
You can also choose Add Existing Item to associate an existing file or directory with your solution. In this case JetBrains Rider will additionally ask you whether you want to copy, move, or create a link to the existing item.
Manage NuGet Packages This command is available on the solution and project nodes. It opens the NuGet window where you can manage NuGet packages.
Unload/Reload Project(s) Use this command to temporarily exclude selected projects from the solution. Unloaded projects are excluded from the build, code inspection and indexing. However, you will still be able to open files Ctrl+Shift+N from unloaded projects and perform textual search Ctrl+Shift+F.
Note that if you want to view or edit the project file (.csproj or .vbproj) you can do so without unloading the project.
Build Solution/Selected Projects This command builds the solution or selected projects.
Run Unit TestsCtrl+;, R Use this command to start unit tests in the selected scope.
Advanced Build Actions | Rebuild Solution/Selected Projects Removes build artifacts from previous builds and then build the selected projects.
Advanced Build Actions | Clean Solution/Selected Projects Removes build artifacts from previous builds.
Advanced Build Actions | Pack Solution/Selected Projects Runs the dotnet pack command for the current solution/selected projects. The command will build the projects and create NuGet packages.
Note that the command only works for .NET Core/ASP.NET Core projects.
Advanced Build Actions | Package Solution/Selected Projects This command helps deploying classic ASP.NET projects. It will use the Package MSBuild target to generate a deployment package in the form of a .zip file, which you can then deploy using the MSDeploy command line.
Reference in C# Interactive Use this command to add reference(s) to the selected project to the C# Interactive session. If no sessions are open, JetBrains Rider will create a new session.
