  hi

  The Dynamic-CSharp-API-Clients proxy required the Castle.DynamicProxy

  You can consider to use Static-CSharp-API-Clients

  Hello i changed the client module to static api but i am getting the same error. And the exception is the same. Do i do sth wrong over here? Is there any specific config that i need to do? To state the app that i use static proxies? Here is an overview of what i have done.

  you can see the folder structure here for static proxies.

  

  here is the client module code.

  using Doohlink.CampaignManagement;

              options.FileSets.AddEmbedded<DoohlinkHttpApiClientModule>();
          });
      }
  }
  

  and here how it is implemented on avalonia ui.

  using Adzup.Player.Services;
  using Adzup.Player.Utils;

      {
  #if DEBUG
          
          PreConfigure<AbpHttpClientBuilderOptions>(options =>

                  clientBuilder.ConfigurePrimaryHttpMessageHandler(HttpClientHelper.GetInsecureHandler);
              });
          });
  #endif
      }
      public override void ConfigureServices(ServiceConfigurationContext context)
      {
          var configuration=context.Services.GetConfiguration();
          Configure<PlayerOptions>(configuration.GetSection(PlayerOptions.Player));
      }
  }

          AbpApplication?.Dispose();
          AbpApplication = null;
      }
  }
  

  and i have this exception again when i try to resolve the appservice.

  appservice is resolve like this in view model.

  _screenAppService = AbpBootstrapper.GetRequiredService<IScreenAppService>()!;
  

  hope you can point me into the right direction. thank you.

  one more thing about the problem. My HttpApi Client module consists of multiple HttpApi Client modules. After i posted the previous message, i have tried with only one of them, then the exception go away, but this time i got another exception message. "no service for type IScreenAppService has been registered". So somehow it can not get the service from ioc container. But i can see the generated service. I couldn't understand what i am doing wrong.

  Hello, I have solved it while i am preparing a minimal project :) Sometimes it is better to create it from scratch. Here is my findings and some questions if you can answer. I can also send the sample test project if you do not understand the questions just let me know.

  So my problem was with the namespace. When i expose my services from the module i create "Controller" folder under httpapi project then set all folders under it here is a screenshot from my folder structure.

  

  so i was trying to inject the isampleappservice from the application service namespace instead of controller namespace. And static generation is creating the isampleappservice for the controller namespace.

  So the first question is if do not put my controller class under controller folder and namespace, it becomes ambiguous namespace for isampleappservice. Cause it is gonna be two isampleappservice comes from application.contracts and from generated folder. How can you fix that? Second question is about "With Contracts and Without Contracts" (https://docs.abp.io/en/abp/latest/API/Static-CSharp-API-Clients#client-proxy-generation) if i create my proxies without contracts first problem is solved. But i want to know downsides of it. Why isampleappservice is created at the first place with contracts? isn't the project referencing to application.contracts anyway? when you create your proxies "with contracts" then shouldn't you reference to application.contracts project? if you do not reference it, as i see it, it doesn't generate the dtos? how it is gonna be functional then?

  As you can see i am little bit confused how should it be used. I want to create a nuget package that can be shared on my private repository since different ui platforms needs to access the backend. Any advice to do that? with or without contracts?

  hi

  1

  Can you share a project to show the namespace problem?

  Thanks

  2

  If the client project already references to the app.contracts package, they should use the --without-contracts parameter. Otherwise, they will have conflicts for app service interfaces and DTO classes (they will be duplicated, one in the referenced app.contracts package, and one in the current project, with the same namespace and name).

  See https://github.com/abpframework/abp/issues/13613

  Hello again, the link was very useful. But i speak too soon. The problem persists still.

  The platform not supported exception gone but when i do the call, then i got an exception below from clientproxybase.

  System.AggregateException: One or more errors occurred. (Object reference not set to an instance of an object)
   ---> System.NullReferenceException: Object reference not set to an instance of an object

  It gets nullreference exception. probably it can not resolve ClientProxyApiDescriptionFinder. Then i realized probably this is related with autofac module, which i can not depend on since ios kernel not allowing it. (Always getting platform not supported exception) https://github.com/abpframework/abp/issues/10929

  It seems like i stucked with this. I am sending you the sample project that i use. If you have some solution, i would like to hear about it. Right now, i wrote my own http client calls with regular HttpClient object. Though it would be very helpful to use the abp client proxies.

  As a note, I use jetbrains rider on mac. When i first created avalonia project it created with target framework as .net7.0. Before i change the framework to .net8.0 I managed to make it work if i wasn't hallucinating :) probably it took .net standard2.0 dlls. But i couldn't make it work after i try to change it back to .net7.0 it was giving me runtime error afterwards. Weird behavior.

  You need to intergate the autofac.

  I tested BookStore.Avalonia.Desktop and shared the source code with you.

  Hello, yes it works for desktop and android, but the problem is in ios. As i mentioned before in my previous posts. Did you try it with ios?

  hi

  I don't have IOS environment.

  But you can remove Autofac. The problem is about the Properity injection.

  So set base service manually.

  using System;
using BookStore.Category.Samples;
using Volo.Abp.DependencyInjection;

namespace BookStore.Avalonia.ViewModels;

public class MainViewModel : ViewModelBase,ISingletonDependency
{
#pragma warning disable CA1822 // Mark members as static
    public string Greeting => "Welcome to Avalonia!";
#pragma warning restore CA1822 // Mark members as static

    public MainViewModel()
    {
        var sampleAppService = AbpBootstrapper.GetRequiredService<ISampleAppService>();
        sampleAppService.As<SampleClientProxy>().LazyServiceProvider = AbpBootstrapper.GetRequiredService<IAbpLazyServiceProvider>();

        var sampleDto = sampleAppService.GetAsync().Result;
    }
}

  thank you @maliming. this is what i was looking for. you are a life saviour. I have tried it and it works nicely. I am gonna close this issue, but just one last thing. Is it possible to override clientproxybase so i don't need to do the same for every service that i am injecting.

  sampleAppService.As<SampleClientProxy>().LazyServiceProvider = AbpBootstrapper.GetRequiredService<IAbpLazyServiceProvider>();

  

  I can write another static method to get the service, but mostly i use constructor injection on my projects. I didn't use it in this example cause of designer data context. any suggestion for that?

  hi

  . Is it possible to override clientproxybase so i don't need to do the same for every service that i am injecting.

  Not currently possible.

  You can consider:

  context.Services.Replace(ServiceDescriptor.Transient<ISampleAppService>(serviceProvider =>
  {
  	var sampleClientProxy = serviceProvider.GetRequiredService<SampleClientProxy>();
  	sampleClientProxy.LazyServiceProvider = serviceProvider.GetRequiredService<IAbpLazyServiceProvider>();
  	return sampleClientProxy;
  }));
