JetBrains Rider, a powerful IDE for .NET developers, offers robust run/debug configurations. Selecting the correct run setting is crucial for efficient development. This guide will walk you through choosing and managing run settings in Rider.

Understanding Run Configurations in Rider

Before diving into selection, let's understand what run configurations are. They define how Rider launches and debugs your application. This includes specifying the startup project, command-line arguments, environment variables, and more. Choosing the right one ensures your application runs as intended.

Types of Run Configurations

Rider supports various run configurations depending on your project type. Common examples include:

• .NET Console Application: This is used to run simple console applications.
• .NET Web Application: This is for web applications, often specifying a web server and port.
• Unit Tests: For executing unit tests using frameworks like NUnit or xUnit.
• External Tools: For launching external applications or scripts.

Choosing the correct type is the first step towards a successful run.

Selecting a Run Setting: A Step-by-Step Guide

There are several ways to select a run configuration in Rider:

Method 1: Using the Run/Debug Configuration Selection Dropdown

1. Locate the Dropdown: Look at the top right corner of the Rider window. You should see a dropdown menu displaying the currently selected run/debug configuration. It often shows the name of your project or the configuration name.

2. Select a Configuration: Click the dropdown arrow. A list of all available run configurations will appear.

3. Choose Your Run Setting: Choose the configuration that matches your needs. If you don't see the configuration you want, you'll need to create a new one (explained in the next section).

4. Run or Debug: Once selected, you can click the "Run" or "Debug" button to start your application.

Method 2: Using the Run/Debug Menu

1. Open the Menu: Go to the "Run" menu at the top of the screen.

2. Select "Edit Configurations...": This opens the "Run/Debug Configurations" dialog.

3. Choose Your Configuration: In this dialog, you can select an existing configuration from the list on the left.

4. Modify or Create: You can modify the settings of an existing configuration or create a new one.

5. Run or Debug: After selecting or creating a configuration, close the dialog and run or debug your application using the "Run" or "Debug" button.

Creating a New Run Configuration

If the configuration you need doesn't exist, you can create one:

1. Open the Run/Debug Configurations Dialog: Follow steps 2 and 3 from Method 2 above.

2. Add New Configuration: Click the "+" button at the top left of the dialog.

3. Select Configuration Type: Choose the appropriate type from the list of templates.

4. Configure Settings: Fill in the required settings based on the type of application you're running. This will often include the startup project, the target framework, and any necessary arguments or environment variables.

5. Apply and Run: Click "Apply" to save the configuration. Then, you can select the new configuration from the dropdown and run your application.

Troubleshooting Common Issues

• No Configurations Appear: Ensure you've built your project successfully. A build error can prevent configurations from appearing.
• Incorrect Configuration Settings: Double-check all settings in the configuration to ensure accuracy. A single misplaced character can cause unexpected behavior.
• Multiple Configurations: Having many configurations can make selection tricky. Organize them logically (e.g., by environment: Development, Testing, Production).

This detailed guide should help you master selecting and managing run settings in JetBrains Rider, enabling you to streamline your development workflow. Remember that understanding your project's needs is key to choosing the correct run setting and avoiding debugging headaches.
