Run/Debug Configuration: .NET Project
Choose a startup project for this configuration.
Note that only projects of executable types (for example, Console Application) could be selected here.
If you want to run a non-executable project (for example, Class Library), use the .NET Executable configuration and choose an executable that will run your project.
A .NET Framework version that will be used to run this configuration.
The path to the executable file of the selected target project is calculated automatically, but you can change it if needed.
Arguments that will be passed to the executable when the configuration is started.
Multiple arguments should be separated with whitespaces.
For some project types (for example, Web Application), JetBrains Rider will fill this field automatically so that the target project could be started correctly.
The working directory is automatically set to the bin/debug path of the selected target project, but you can change it if needed.
Here you can specify custom environment variables for the target executable.
Both dotnet and Mono support setting custom runtime arguments when launching an application. For example Mono supports many runtime arguments to customize how your application is run. You can select the garbage collector to be used (
Use mono runtime
If you are working on Windows, you can check how your application works with the mono runtime. JetBrains Rider will use the mono executable specified on thepage of JetBrains Rider settings Ctrl+Alt+S.
To debug with mono runtime, you need:
Use external console:
This checkbox does not affect classic .NET application types (for example, .NET Console Application) — their output in always shown in an external window.
Browser / Live Edit tab
In this tab, configure the behaviour of the browser and enable debugging the client-side code of the application. This functionality is provided through a
In the field in this area, specify a project HTML file to create a correct URL to this file according to the project root to be started on the built-in web server. For example, if you choose project_root/inner_folder/index.html the resulting URL will be http://localhost:63342/project_root/inner_folder/index.html. If you select the After Launch checkbox, the browser will open this page automatically after the application starts. Alternatively you can view the same result by opening the page with this URL address in the browser of your choice manually.
Select this checkbox to automatically open the browser. From the list, select the browser to use:
Select this checkbox to enable debugging the client-side code in the selected browser.
When you edit a run configuration (but not a run configuration template), you can specify the following options:
Specify a name for the run/debug configuration to quickly identify it when editing or running the configuration, for example, from the Run popup Alt+Shift+F10.
Allow parallel run
Select to allow running multiple instances of this run configuration in parallel.
By default, it is disabled, and when you start this configuration while another instance is still running, JetBrains Rider suggests to stop the running instance and start another one. This is helpful when a run/debug configuration consumes a lot of resources and there is no good reason to run multiple instances.
Store as project file
Save the file with the run configuration settings to share it with other team members. The default location is .idea/runConfigurations. However, if you do not want to share the .idea directory, you can save the configuration to any other directory within the project.
By default, it is disabled, and JetBrains Rider stores run configuration settings in .idea/workspace.xml.
The tree view of run/debug configurations has a toolbar that helps you manage configurations available in your solution as well as adjust default configurations templates.
Create a run/debug configuration.
Delete the selected run/debug configuration. Note that you cannot delete default configurations.
Create a copy of the selected run/debug configuration. Note that you create copies of default configurations.
The button is displayed only when you select a temporary configuration. Click this button to save a temporary configuration as permanent.
Move into new folder / Create new folder. You can group run/debug configurations by placing them into folders.
To create a folder, select the configurations within a category, click , and specify the folder name. If only a category is in focus, an empty folder is created.
Then, to move a configuration into a folder, between the folders or out of a folder, use drag or and buttons.
To remove grouping, select a folder and click .
Click this button to sort configurations in the alphabetical order.
In this area, you can specify tasks to be performed before starting the selected run/debug configuration. The tasks are performed in the order they appear in the list.
Click this icon to add one of the following available tasks:
Click this icon to remove the selected task from the list.
Click this icon to edit the selected task. Make the necessary changes in the dialog that opens.
Click these icons to move the selected task one line up or down in the list. The tasks are performed in the order that they appear in the list.
Show this page
Select this checkbox to show the run/debug configuration settings prior to actually starting the run/debug configuration.
Activate tool window
Otherwise, if the checkbox is cleared, the tool window is hidden. However, when the configuration is running, you can open the corresponding tool window for it yourself by pressing Alt+4 or Alt+5.
