Marks an assembly-level opt-in attribute whose source generator provides [AspireExportAttribute](/reference/api/csharp/aspire.hosting/aspireexportattribute.md) coverage.

## Definition

```csharp
namespace Aspire.Hosting;

public sealed class AspireExportProviderAttribute
    : System.Attribute
{
    // ...
}
```

## Remarks

Source generators can apply this attribute to their opt-in attribute type so the Aspire integration analyzer recognizes assemblies whose exports are produced during compilation. The opt-in attribute itself must target assemblies.
