- Version: `13.5.3-preview.1.26425.3`
- Namespace: `Aspire.Hosting`

- Source: [GitHub](https://github.com/microsoft/aspire/blob/b5f143315ffb6968ea939a9978797a5b20e4c688/src/Aspire.Hosting.Radius/CloudProviders/RadiusCloudProviderExtensions.cs)

Cloud-provider configuration entry points for [RadiusEnvironmentResource](/reference/api/csharp/aspire.hosting.radius/radiusenvironmentresource.md). These extensions attach a `Annotations.RadiusCloudProvidersAnnotation` to the environment that the publisher consumes to emit `providers.azure` / `providers.aws` scope blocks and to schedule `rad credential register` invocations during deploy.
