interface DurableTaskHubResource
  extends IExpressionValue,
    IManifestExpressionProvider,
    IResource,
    IResourceWithConnectionString,
    IResourceWithParent,
    DurableTaskSchedulerResource]],
    IValueProvider,
    IValueWithReferences,
    IResourceWithAzureFunctionsConfig {
  readonly connectionStringExpression: ReferenceExpression;
  readonly taskHubName: ReferenceExpression;
  withTaskHubName(taskHubName: ParameterResource): DurableTaskHubResource;
}
```
