## Remarks

This type is reserved for resources that carry [IProjectMetadata](/reference/api/csharp/aspire.hosting/iprojectmetadata.md). Aspire hands the project path (and launch profile) to the IDE, which owns building and launching the project, so no process fallback is offered for resources using this type.
