Using the dynamic controllers from WPF/Xamarin host in Owin #415

  I am actually trying to use a Windsor IHttpControllerActivator now.

  using Abp.Modules; using Castle.Windsor; using System; using System.Collections.Generic; using System.Linq; using System.Net.Http; using System.Text; using System.Threading.Tasks; using System.Web.Http.Controllers; using System.Web.Http.Dispatcher;

  namespace ReadyCare.Owin.WebApi.Host { public class WindsorCompositionRoot : AbpModule, IHttpControllerActivator { //private readonly IWindsorContainer container;

      public WindsorCompositionRoot()
      //public WindsorCompositionRoot(IWindsorContainer container)
      {
          //this.container = container;
      }
  
      public IHttpController Create(
          HttpRequestMessage request,
          HttpControllerDescriptor controllerDescriptor,
          Type controllerType)
      {
          var controller =
              (IHttpController)this.IocManager.IocContainer.Resolve(controllerType);
  
          request.RegisterForDispose(
              new Release(
                  () => this.IocManager.IocContainer.Release(controller)));
  
          return controller;
      }
  
      private class Release : IDisposable
      {
          private readonly Action release;
  
          public Release(Action release)
          {
              this.release = release;
          }
  
          public void Dispose()
          {
              this.release();
          }
      }
  }
  

  }

  And the startup is now

  using Abp; using Abp.Modules; using Abp.WebApi.Configuration; // Add the following usings: using Owin; using ReadyCare.WebApi; using System.Web.Http; using System.Web.Http.Dispatcher;

  namespace ReadyCare.Owin.WebApi.Host { [DependsOn(typeof(ReadyCareWebApiModule))] public class Startup : AbpModule { // This method is required by Katana: public new void Configuration(IAppBuilder app) { AbpBootstrapper bootstrapper = new AbpBootstrapper();

          bootstrapper.Initialize();
  
          GlobalConfiguration.Configuration.Services.Replace(
              typeof(IHttpControllerActivator),
          new WindsorCompositionRoot());
  
          var httpConfiguration = IocManager.Resolve<IAbpWebApiModuleConfiguration>().HttpConfiguration;
  
          //httpConfiguration.DependencyResolver = windsorDependencyResolver;
  
          // Use the extension method provided by the WebApi.Owin library:
          app.UseWebApi(httpConfiguration);
      }
  }
  

  }

  But I get a "Object reference not set to an instance of an object." when the startup is called in the main

  using Abp.Modules; using ReadyCare.WebApi; using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using Microsoft.Owin.Hosting;

  namespace ReadyCare.Owin.WebApi.Host {

  class Program
  {
      static void Main(string[] args)
      {
          string baseUri = "http://localhost:8080";
  
          Console.WriteLine("Starting web Server...");
          try
          { 
          WebApp.Start<Startup>(baseUri);
          }
          catch(Exception ex)
          {
              string msg = ex.GetBaseException().Message;
          }
          
          Console.WriteLine("Server running at {0} - press Enter to quit. ", baseUri);
          Console.ReadLine();
      }
  }
  

  }

  Note that my ReadyCareWebApiModule is intialising fine. like this

  using System.Reflection; using Abp.Application.Services; using Abp.Modules; using Abp.WebApi; using Abp.WebApi.Controllers.Dynamic.Builders; using ReadyCare.Application; using ReadCare.ViewModels;

  namespace ReadyCare.WebApi { [DependsOn(typeof(AbpWebApiModule), typeof(ReadyCareApplicationModule))] public class ReadyCareWebApiModule : AbpModule { public override void Initialize() { IocManager.RegisterAssemblyByConvention(Assembly.GetExecutingAssembly());

          DynamicApiControllerBuilder
                     .For<IImageApplicationService<PatientBodyImageViewModel>>("telstra/readycare/ImageApplicationService")
                     .WithConventionalVerbs()
                     .Build();
          //DynamicApiControllerBuilder
          //    .ForAll<IApplicationService>(typeof(ReadyCareApplicationModule).Assembly, "telstra/readycare")
          //    .WithConventionalVerbs()
          //    .Build();
  
         
  
      }
  }
  

  }

  Where I am using a generic for the ImageApplicationService as the DTOs are viewmodels for Xamarin/WPF and simple dtos for Web apps.
