}
```

## Constructors

- [ParameterProcessor(ResourceNotificationService, ResourceLoggerService, IInteractionService, ILogger<ParameterProcessor>, DistributedApplicationExecutionContext, IDeploymentStateManager, IUserSecretsManager)](/reference/api/csharp/aspire.hosting/parameterprocessor/constructors.md#constructor-resourcenotificationservice-resourceloggerservice-iinteractionservice-ilogger-parameterprocessor-distributedapplicationexecutioncontext-ideploymentstatemanager-iusersecretsmanager) -- Handles processing of parameter resources during application orchestration.

## Methods

- [DeleteParameterAsync(ParameterResource, CancellationToken)](/reference/api/csharp/aspire.hosting/parameterprocessor/methods.md#deleteparameterasync-parameterresource-cancellationtoken) : `Task` -- Deletes a parameter value from the deployment state and marks it as unresolved.
- [InitializeParametersAsync(IEnumerable<ParameterResource>, bool)](/reference/api/csharp/aspire.hosting/parameterprocessor/methods.md#initializeparametersasync-ienumerable-parameterresource-bool) : `Task` -- Initializes parameter resources and handles unresolved parameters if interaction service is available.
- [InitializeParametersAsync(DistributedApplicationModel, bool, CancellationToken)](/reference/api/csharp/aspire.hosting/parameterprocessor/methods.md#initializeparametersasync-distributedapplicationmodel-bool-cancellationtoken) : `Task` -- Initializes parameter resources by collecting dependent parameters from the distributed application model and handles unresolved parameters if interaction service is available.
- [SetParameterAsync(ParameterResource, CancellationToken)](/reference/api/csharp/aspire.hosting/parameterprocessor/methods.md#setparameterasync-parameterresource-cancellationtoken) : `Task` -- Prompts the user to set a value for a single parameter.
