## ATS metadata

### ATS export

- Type ID: `Aspire.Hosting.Dotnet/DotnetProjectResource`
- Public instance properties are exported as ATS capabilities.

## Remarks

A [DotnetProjectResource](/reference/api/csharp/aspire.hosting.dotnet/dotnetprojectresource.md) is added by path and is launched as an executable: `dotnet run --project <path>` for a project file, or `dotnet run --file <path>` for a file-based app (a `.cs` file).

Automatic publishing is not supported. Use `AddProject<TProject>(...)` or `AddCSharpApp(...)` for standard .NET project publishing, explicitly configure container publishing with `PublishAsDockerFile(...)`, or exclude an intentionally run-only resource with `ExcludeFromManifest()`.
