## PackageName

- Name: `PackageName`
- Modifiers: `get`
- Returns: `string`
- Source: [GitHub](https://github.com/microsoft/aspire/blob/f4c27f2d43ddc1cacd0dd083b30d1fea1cee7a62/src/Aspire.TypeSystem/ApiReferenceExportOptions.cs#L67)

<a id="packageversion"></a>

## PackageVersion

- Name: `PackageVersion`
- Modifiers: `get`
- Returns: `string`
- Source: [GitHub](https://github.com/microsoft/aspire/blob/f4c27f2d43ddc1cacd0dd083b30d1fea1cee7a62/src/Aspire.TypeSystem/ApiReferenceExportOptions.cs#L82)

Gets the version label recorded for this export, as supplied by the caller.

```csharp
public string PackageVersion { get; }
```

## Remarks

Consumers key published documentation on this value, so callers are expected to pass the exact version that was restored. Nothing on this type can confirm that: an exporter sees loaded assemblies, not the package resolution that produced them, so any value -- including a floating or range expression -- would be recorded verbatim. Exactness therefore belongs where the restore is decided. `aspire sdk export` rejects a floating or range version before the scanner is built, pins the requested version so an unavailable one fails the restore instead of resolving upward, and refuses a package a repository checkout would build in place of the requested one.
