    }
}
```

## Parameters

- `name` (`string`)
  The name of the resource in the distributed application model.
- `targetAzureResource` ([AzureProvisioningResource](/reference/api/csharp/aspire.hosting.azure/azureprovisioningresource.md))
  The Azure resource that the roles are assigned on.
- `ownerResource` (`IResource?`)
  The Aspire resource that owns this set of role assignments, or `null` for global role assignments granted to the deployment principal.
- `identityResource` ([AzureUserAssignedIdentityResource?](/reference/api/csharp/aspire.hosting.azure/azureuserassignedidentityresource.md))
  The user-assigned managed identity whose principal receives the role assignments, or `null` for global role assignments granted to the deployment principal.
- `configureInfrastructure` (`Action<AzureResourceInfrastructure>`)
  Callback to configure the Azure role assignment resources.

## Remarks

When [AzureRoleAssignmentResource.OwnerResource](/reference/api/csharp/aspire.hosting.azure/azureroleassignmentresource/properties.md#ownerresource) is non- `null`, the role assignments are granted to the managed identity ( [AzureRoleAssignmentResource.IdentityResource](/reference/api/csharp/aspire.hosting.azure/azureroleassignmentresource/properties.md#identityresource)) owned by that Aspire resource. When [AzureRoleAssignmentResource.OwnerResource](/reference/api/csharp/aspire.hosting.azure/azureroleassignmentresource/properties.md#ownerresource) is `null`, the role assignments are global and are granted to the deployment principal.
