  To generate proxies for a new integration service in an ABP microservice solution, ensure the following steps are completed:

  1. Define the Integration Service Interface
     • The interface must inherit from IIntegrationService (or IApplicationService for older versions).
     • Place the interface in the Application.Contracts project of the microservice.

  public interface IMyIntegrationService : IIntegrationService
     {
         Task<MyDto> GetDataAsync(Guid id);
     }
  

  2. Implement the Integration Service
     • Implement the interface in the Application project.

  public class MyIntegrationService : MyAppService, IMyIntegrationService
     {
         public Task<MyDto> GetDataAsync(Guid id)
         {
             // Implementation
         }
     }
  

  3. Expose Integration Services in the Provider Microservice
     • In the provider microservice's module (e.g., IdentityServiceHttpApiModule), expose integration services:

  Configure<AbpAspNetCoreMvcOptions>(options =>
     {
         options.ExposeIntegrationServices = true;
     });
  

  4. Build All Projects

     • Ensure all projects are built so the new interface and implementation are available.

  5. Generate Proxies in the Consumer Microservice

     • In the consumer microservice, add a reference to the provider's Application.Contracts project.
     • Run the proxy generation command in the consumer microservice's directory:

  abp generate-proxy -t csharp
  

  • Or use ABP Studio's proxy generation feature.

  6. Check Remote Service Configuration
     • Ensure the remote service is configured in appsettings.json:

  "RemoteServices": {
       "IdentityService": {
         "BaseUrl": "https://localhost:PORT"
       }
     }
  

  7. Register Static Proxies
     • In the consumer's module, register the static HTTP client proxies:

  context.Services.AddStaticHttpClientProxies(
         typeof(YourProviderApplicationContractsModule).Assembly,
         "IdentityService"
     );
  

  Common Issues:

  • If the interface does not inherit from IIntegrationService or is not in the correct project, proxies will not be generated.
  • If the provider microservice is not running or not exposing integration services, the CLI cannot discover the endpoints.
  • Always rebuild the solution after adding new services.

  The generate proxy issue resolved, it caused by a typo which the interface of the integration service not follow the conventional.
