Aspire Host run configuration

The .NET Aspire plugin provides a special run configuration for the .NET Aspire Host projects. It discovers such projects by the <IsAspireHost>true</IsAspireHost> MSBuild property. For each launchSettings.json profile of this project, the corresponding run configuration will be generated.

Description

Project

.NET Aspire host project (defined by the IsAspireHost property).

Launch profile

A profile name from the launchSettings.json file. After changing the profile, the Environment Variables and URL fields will be updated accordingly.

Arguments

Arguments that will be passed to the executable when the configuration is started.

Multiple arguments should be separated with whitespaces.

Working directory

The working directory is automatically set to the project root path of the selected target project, but you can change it if needed.

Environment variables

List of environment variables. The list is defined by the environmentVariables property from the launchSettings.json file.

Use Podman container runtime

Select this checkbox if you are using Podman. This option automatically sets the environment variable DOTNET_ASPIRE_CONTAINER_RUNTIME to podman.

This run configuration allows you to run or debug multiple projects registered in the Host project.

Debugging multiple Aspire projects

A separate node will also be created in the Services tool window. It allows you to monitor resources while Aspire Host is running. For example, you can find resource properties, endpoints, environment variables, and read logs there.
