WcfClient.Resilient

Provides a resilient WCF client as a web service reverse proxy built on top of GenericWcfClient, featuring support for Polly's retry actions and the circuit breaker pattern.

Configuration

builder.Services.AddWcfGenericClient<IdentityService, SoapSettings>(
    config, "SoapSettings");

builder.Services.AddResilientWcfClientInstaller<IdentityService, DefaultPolicyFactory<IdentityService>>(
    config, "WcfResilient");

• AddWcfGenericClient: Registers the IGenericWcfClient for the IdentityService.
• AddResilientWcfClientInstaller: Adds resilient behavior to the GenericWcfClient (web service proxy) for the service that implements the IdentityService interface.

Note: The order of these registrations in the dependency injection (DI) container is important for the correct setup of resilient behavior.

Resilient Settings Example

The resilient settings for the provided example:

"WcfResilient": {
      "PolicyRetryAttempts": 3,
      "AsyncPolicyRetryAttempts": 3,
      "RetryAttemptInMilliseconds": 2000,
      "AsyncRetryAttemptInMilliseconds": 2000,
      "CircuitBreakerPolicyRetryAttempts": 2,
      "AsyncCircuitBreakerPolicyRetryAttempts": 2,
      "CircuitBreakerRetryAttemptInMilliseconds": 180000,
      "AsyncCircuitBreakerRetryAttemptInMilliseconds": 180000
    }

This configuration defines the number of retry attempts and the delay between retries for both synchronous and asynchronous calls, as well as the circuit breaker thresholds.
