I am trying to build a routing infrastructure and I use Autofac as IoC container. I read the wiki and I know these steps:
ContainerBuilder builder = new ContainerBuilder();
builder.Register(c => new Logger()).As<ILogger>();
builder.Register(c => new EchoService(c.Resolve<ILogger>())).As<IEchoService>();
using (IContainer container = builder.Build())
{
Uri address = new Uri("http://localhost:8080/EchoService");
ServiceHost host = new ServiceHost(typeof(EchoService), address);
host.AddServiceEndpoint(typeof(IEchoService), new BasicHttpBinding(), string.Empty);
host.AddDependencyInjectionBehavior<IEchoService>(container);
host.Description.Behaviors.Add(new ServiceMetadataBehavior {HttpGetEnabled = true, HttpGetUrl = address});
host.Open();
Console.WriteLine("The host has been opened.");
Console.ReadLine();
host.Close();
Environment.Exit(0);
}
I do have this code here to satisfy my scenario:
builder.RegisterType<RoutingService>().As<ISimplexDatagramRouter>().InstancePerLifetimeScope();
builder.Register(c =>
{
var routingConfiguration = new RoutingConfiguration();
routingConfiguration.RouteOnHeadersOnly = false;
return routingConfiguration;
}).As<RoutingConfiguration>();
builder.Register(c =>
{
var publisherServiceHost = new ServiceHost(typeof(RoutingService));
publisherServiceHost.AddServiceEndpoint(typeof(ISimplexDatagramRouter), new NetTcpBinding(), "some address");
publisherServiceHost.Description.Behaviors.Add(new RoutingBehavior(c.Resolve<RoutingConfiguration>()));
return publisherServiceHost;
}).As<ServiceHost>();
This doesn't work, as I get an error from Autofac as it can't find condtructor for RoutingService (its constructor is private).
Do you have any hint?
As far as I know the RoutingService class has no constructors defined. You can see that if you try to do this:
RoutingService rs = new RoutingService();
You will get an error from the compiler saying:
The type System.ServiceModel.Routing.RoutingService has no constructors defined.

I have the following error when I start the masstransit with azure bus.Start(); on my function StartService() I have configuring my azure with masstransit and autofact. The error:
MassTransit.Azure.ServiceBus.Core.ServiceBusConnectionException
HResult=0x80131500
Message=ReceiveTransport faulted: sb://softbaire-amilkar.servicebus.windows.net/;SharedAccessKeyName=**REMOVED**;SharedAccessKey=**REMOVED**/TeamTimeManager
Source=mscorlib
configuration with masstransit:
public static IContainer ConfigureContainer()
{
var builder = new ContainerBuilder();
builder.AddMassTransit(cfg =>
{
cfg.SetKebabCaseEndpointNameFormatter();
cfg.AddConsumer<TeamTimeManager>();
cfg.UsingAzureServiceBus((context, conf) =>
{
var settings = new HostSettings
{
ServiceUri = new Uri("sb://softbaire-amilkar.servicebus.windows.net/;SharedAccessKeyName=RootManageSharedAccessKey;SharedAccessKey=UeIC0z5RPCt25SjnWdss2ssP5a6msUKNJxmLnBpm26g="),
TokenProvider = TokenProvider.CreateManagedIdentityTokenProvider()
};
conf.Host(settings);
conf.ConfigureEndpoints(context);
});
});
return builder.Build();
}
this is where I start the service and I get the error:
public void StartService()
{
var container = CreatorContainer.ConfigureContainer();
var bus = container.Resolve<IBusControl>();
if (host != null)
{
host.Close();
}
host = new ServiceHost(typeof(TeamTimeManager));
utilHost = new ServiceHost(typeof(TeamTimeUtilityManager));
bus.Start();
source.TraceInformation("Starting TeamTimeManager Azure Bus...");
host.Open();
source.TraceInformation("TeamTimeManager Started!");
utilHost.Open();
utilSource.TraceInformation("Starting TeamTimeUtilityManager...");
}
UPDATE
this problem is solved when I comment on the line:
cfg.AddConsumer<TeamTimeManager>();
if I add a queue or a subscription the problem appears again
BUG
https://github.com/Azure/azure-sdk-for-net/issues/8627
It's likely permissions. MassTransit requires Manage, and you're configuring the managed identity token provider.
Remove the shared access credentials from the connection string, since they would conflict with the managed identity provider.
Make sure the service identity has Manage permissions on the namespace.
Well, the problem was in the token provider.
The problem was that the token generated was connected to azure but without any queue or topic register, the problem started when I wanted to register queues and topics, when I wanted to generate the connection with the queue or a topic I got an error because the token was invalid for my user(weird), so... I changed the method to generate the token and everything started to work correctly.
Before:
var settings = new HostSettings
{
ServiceUri = new Uri("sb://xxxx-busazure.servicebus.windows.net"),
TokenProvider = TokenProvider.CreateManagedIdentityTokenProvider()
};
After: now I'm using CreateSharedAccessSignatureTokenProvider() you need to send as parameters the "SharedAccessKeyName" and the "SharedAccessKey"
var settings = new HostSettings
{
ServiceUri = new Uri("sb://xxxxx-busazure.servicebus.windows.net"),
TokenProvider = TokenProvider.CreateSharedAccessSignatureTokenProvider("RootManageSharedAccessKey", "xxxxxxxxxxxxxxx=")
};
queues and everything is running smoothly, Final configuration method:
public static IContainer ConfigureContainer()
{
var builder = new ContainerBuilder();
builder.AddMassTransit(cfg =>
{
cfg.SetKebabCaseEndpointNameFormatter();
cfg.AddServiceBusMessageScheduler();
cfg.AddConsumer<TeamTimeManager>();
cfg.UsingAzureServiceBus((context, conf) =>
{
conf.UseServiceBusMessageScheduler();
var settings = new HostSettings
{
ServiceUri = new Uri("sb://amilkar-busazure.servicebus.windows.net"),
TokenProvider = TokenProvider.CreateSharedAccessSignatureTokenProvider("RootManageSharedAccessKey", "xxxxxxxxxxxxxxxxxxxxxx")
};
conf.Host(settings);
conf.ReceiveEndpoint("team-time-manager", e =>
{
e.ConfigureConsumer<TeamTimeManager>(context);
});
conf.ConfigureEndpoints(context);
});
});
return builder.Build();
}

this.userService = userService; **showing NULL**
this.conversationState = conversationState;

A tempory solution at least for me was to inject the service in a razor page to get the user there and pass the user to the service.
note: this should be a comment but i dont have enough repuation to comment.
Need to resolve IRabbitMqHost for adding handler to bus after bus started.
Steps to Reproduce
Register "IRabbitMqHost" in masstransit configuration
Try to resolve "IRabbitMqHost" in autofac
Then "Exception of type 'Autofac.Core.Registration.ComponentNotRegisteredException' was thrown"
builder.Register(context =>
{
var bus = Bus.Factory.CreateUsingRabbitMq(opt =>
{
var result = new List<string>();
Configuration.GetSection("RabbitMq:HostNames").Bind(result);
var host = opt.Host(result[0], Configuration.GetValue<string>("RabbitMq:VirtualHost"), h =>
{
h.Username(Configuration.GetValue<string>("RabbitMq:Username"));
h.Password(Configuration.GetValue<string>("RabbitMq:Password"));
});
builder.Register<IRabbitMqHost>(a => host);
});
return bus;
}).As<IBus>()
.As<IBusControl>();
builder.Build().Resolve<IRabbitMqHost>()
Expected Behavior
Need to resolve IRabbitMqHost which configured in IBus configuration, because need to add handler after bus started.
Need _rabbitMqHost.ConnectReceiveEndpoint()...
Actual Behavior
container.Resolve throws exception belove.
image in https://github.com/MassTransit/MassTransit/issues/1470
When registered to bus in autofac gave delegate function which create bus instance and registers host. But this delegate not invoked yet. After build the containerbuilder and tried to resolve IBus, then it invoke delegate and registered IRabbitMqHost but not built container. Then when i try to solve IRabbitMqHost it not find registered component because added container not built.
this code worked for me;
builder.Register(context =>
{
var bus = Bus.Factory.CreateUsingRabbitMq(opt =>
{
var result = new List<string>();
Configuration.GetSection("RabbitMq:HostNames").Bind(result);
var host = opt.Host(result[0], Configuration.GetValue<string>("RabbitMq:VirtualHost"), h =>
{
h.Username(Configuration.GetValue<string>("RabbitMq:Username"));
h.Password(Configuration.GetValue<string>("RabbitMq:Password"));
});
ContainerBuilder b = new ContainerBuilder();
b.Register<IRabbitMqHost>(a => host).SingleInstance();
b.Update(ApplicationContainer);
});
return bus;
}).As<IBus>()
.As<IBusControl>()
.SingleInstance();

I am getting this error when hosting my application on azure:
The data protection operation was unsuccessful. This may have been caused by not having the user profile loaded for the current thread's user context, which may be the case when the thread is impersonating.
When trying creating a user or resending a confirmation email.
This article:
http://tech.trailmax.info/2014/06/asp-net-identity-and-cryptographicexception-when-running-your-site-on-microsoft-azure-web-sites/
says that you should create a single instance on the startup class, but I am using autofac, so I have done this:
builder.Register(c => new IdentityFactoryOptions<UserProvider>() { DataProtectionProvider = new DpapiDataProtectionProvider(c.Resolve<PiiiCKConfig>().Issuer) }).SingleInstance();
and then in my UserManager constructor, I do this:
// Get our data protection provider
var dataProtectionProvider = options.DataProtectionProvider;
// If we have on
if (dataProtectionProvider != null)
{
// Set our token provider
UserTokenProvider = new DataProtectorTokenProvider<User>(dataProtectionProvider.Create("PiiiK Identity"))
{
// Set our long the email confirmation token will last
TokenLifespan = TimeSpan.FromHours(6)
};
}
But I still get the error.
Does anyone know how I can solve this issue?
According to your description, I checked this issue on my side and I could reproduce this issue. Per my test, you could follow the approaches below to solve this issue:
builder.Register(c => new IdentityFactoryOptions<UserProvider>() { DataProtectionProvider = new DpapiDataProtectionProvider(c.Resolve<PiiiCKConfig>().Issuer) }).SingleInstance();
You could using IAppBuilder.GetDataProtectionProvider() instead of declaring a new DpapiDataProtectionProvider, based on the above code, you need to modify it as follows:
builder.Register(c => new IdentityFactoryOptions<UserProvider>()
{
DataProtectionProvider = app.GetDataProtectionProvider()
}).SingleInstance();
Or
builder.Register<IDataProtectionProvider>(c => app.GetDataProtectionProvider()).SingleInstance();
Additionally, here is a similar issue, you could refer to here.
UPDATE:
Here is the code snippet of Startup.Auth.cs as follows:
public partial class Startup
{
public void ConfigureAuth(IAppBuilder app)
{
var builder = new ContainerBuilder();
builder.RegisterControllers(typeof(MvcApplication).Assembly);
builder.Register(c => new IdentityFactoryOptions<ApplicationUserManager>()
{
DataProtectionProvider = app.GetDataProtectionProvider()
}).SingleInstance();
//Or
//builder.Register<IDataProtectionProvider>(c =>app.GetDataProtectionProvider()).SingleInstance();
var container = builder.Build();
DependencyResolver.SetResolver(new AutofacDependencyResolver(container));
}
}
I have a project that is both OWIN and Web API 2.
I have tried to follow the instructions as best as I can.
Inside my Configration method in the StartupConfig class I have this:
// Get our configuration
var config = new HttpConfiguration();
var container = ConfigureInversionOfControl(app, config);
var scope = config.DependencyResolver.GetRequestLifetimeScope();
var serverOptions = ConfigureOAuthTokenGeneration(app, scope);
//** removed for brevity **//
// Cors must be first, or it will not work
app.UseCors(CorsOptions.AllowAll);
// Register the Autofac middleware FIRST. This also adds
// Autofac-injected middleware registered with the container.
app.UseAutofacMiddleware(container);
//app.UseAutofacWebApi(config);
app.UseOAuthAuthorizationServer(serverOptions);
app.UseWebApi(config);
My ConfigurInversionOfControl method looks like this:
private static IContainer ConfigureInversionOfControl(IAppBuilder app, HttpConfiguration config)
{
// Create our container
var builder = new ContainerBuilder();
// You can register controllers all at once using assembly scanning...
builder.RegisterApiControllers(Assembly.GetExecutingAssembly());
// Add our dependencies (Can't use life because this is available to all controllers http://stackoverflow.com/questions/36173210/get-same-instance-of-a-component-registered-with-autofac-as-instanceperlifetimes)
builder.RegisterType<UnitOfWork<DatabaseContext>>().As<IUnitOfWork>().InstancePerRequest();
// Register our services
builder.Register(c => new AdvancedEncryptionStandardProvider(ConfigurationManager.AppSettings["rm:key"], ConfigurationManager.AppSettings["rm:secret"])).As<IAdvancedEncryptionStandardProvider>();
builder.RegisterType<LogService>().As<ILogService>();
builder.RegisterType<EmailService>().As<IEmailService>();
builder.RegisterType<RefreshTokenService>().As<IRefreshTokenService>();
// Register our providers
builder.Register(c => new SendGridProvider(c.Resolve<IUnitOfWork>(), c.Resolve<IEmailService>(), ConfigurationManager.AppSettings["SendGridApiKey"])).As<ISendGridProvider>();
builder.RegisterType<LogProvider>().As<ILogProvider>();
builder.RegisterType<RefreshTokenProvider>().As<IAuthenticationTokenProvider>();
builder.RegisterType<OAuthProvider>().As<OAuthProvider>();
// Build
var container = builder.Build();
// Lets Web API know it should locate services using the AutofacWebApiDependencyResolver
config.DependencyResolver = new AutofacWebApiDependencyResolver(container);
// Return our container
return container;
}
Now I have set this up (I assume correctly). How do I resolve one of the services in my StartupConfig class?
I need to be able to create an instance of the OAuthProvider and RefreshTokenProvider. I tried something similar to this:
// Get our providers
var authProvider = scope.Resolve<OAuthProvider>();
var refreshTokenProvider = scope.Resolve<IAuthenticationTokenProvider>();
// Create our OAuth options
return new OAuthAuthorizationServerOptions()
{
AllowInsecureHttp = true, // TODO: Remove this line
TokenEndpointPath = new PathString("/oauth/access_token"),
AccessTokenExpireTimeSpan = TimeSpan.FromDays(1),
AccessTokenFormat = new Business.Authentication.JwtFormat("http://localhost:62668"),
Provider = authProvider,
RefreshTokenProvider = refreshTokenProvider
};
But when it reaches the line var authProvider = scope.Resolve<OAuthProvider>();, I get an error stating:
Parameter cannot be null: Parameter name: context
Now I would assume that the context has not been created yet, so I assume I am doing something wrong with my resolve.
Can anyone help?
This was actually really simple.
I needed the change the scope from:
var scope = config.DependencyResolver.GetRequestLifetimeScope();
to
var scope = config.DependencyResolver.GetRootLifetimeScope();
I assume because the "request" is not available in the StartupConfig class.
Anyway, changing this fixed my issue.
