In my startup.cs File i am doing the following:
//Register Background Task
services.AddHostedService<HostedMQTTService>();
The problem is, that it seems to me that the hosted service is blocking the user-interface/webserver threads because i can not access the url of the .net 6 mvc application.
Could you give me a hint or a solution to this problem?
Thanks.

You will need to change your StartAsync-method to something like this:
public Task StartAsync(CancellationToken cancellationToken)
{
return Task.Run(() =>
{
_logger.LogInformation("Background-Service started...");
while (!cancellationToken.IsCancellationRequested)
{
try
{
//No Object is created
if (this.MqttClient == null)
{
_logger.LogInformation("Try to establish new MQTT Client");
this.MqttClient = CreateNewMqttConnection();
}
else if (this.MqttClient.IsConnected == false)
{
_logger.LogInformation("MQTT Client is disconnected... Try to reconnect!");
this.MqttClient = CreateNewMqttConnection();
}
}
catch (Exception ex)
{
_logger.LogError(ex, "Ein schwerwiegender Fehler im MQTT Background-Service ist aufgetreten.");
}
}
});
}

You are blocking the process, because your hosted service never starts.
Remove the while(true) loop from the Start method.
Ensure base.StartAsync(cancellationToken); is always called.
Edit: I saw you implement the IHostedService interface. Try to inherits from the BackgroundService class

OpenIddict migration from v2 to v3 rc1 - Login success, Authorize Failed

I have tried to migration my project from v2 to v3 and I think i have updated everything, but for some reason i can login fine and i get an access_token returned, but this access_token fails to authorize a request. Not sure why, but if someone can see anything obvious that would be great. My application is a web Api with a angular2 web application for the client.
In v2 i was using JWT, but i understand that this is the default in v3 so i may have some code that needs to removed for this to work.
To restrict a controllers methods or a single method, i am using [Authorize] attribute.

MVC - Mixed Auth - OWIN + Windows Auth

I need to have both windows authentication and owin (forms) authentication but i can't get it to work.
Probably the best option is to have two sites that have different authentication methods.
I found a project that does what i want: MVC5-MixedAuth. But it uses IISExpress and i can't get it to work with Local IIS.
The error that occurs is:
Request filtering is configured on the Web server to deny the request because the query string is too long.
If i remove all my ConfigureAuth() method inside Startup.Auth.cs it doesn't throw the error but i can't login because it is needed to do CookieAuthentication.
Startup.Auth.cs:
public void ConfigureAuth(IAppBuilder app)
{
app.CreatePerOwinContext(dbEmployeePortal.Create);
app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
app.CreatePerOwinContext<ApplicationSignInManager>(ApplicationSignInManager.Create);
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
LoginPath = new PathString("/Account/Login"),
Provider = new CookieAuthenticationProvider
{
OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, UserMaster, int>
(
validateInterval: TimeSpan.FromMinutes(30),
regenerateIdentityCallback: (manager, user) => user.GenerateUserIdentityAsync(manager),
getUserIdCallback: (id) => (Int32.Parse(id.GetUserId()))
)
}
});
app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
app.UseTwoFactorSignInCookie(DefaultAuthenticationTypes.TwoFactorCookie, TimeSpan.FromMinutes(5));
app.UseTwoFactorRememberBrowserCookie(DefaultAuthenticationTypes.TwoFactorRememberBrowserCookie);
}
Any idea?
UPDATE 1
The error
Request filtering is configured on the Web server to deny the request because the query string is too long.
appears because occurs a login loop when it tries to reach the login page.

Resolved!
I followed the example: MVC5-MixAuth
Credits: Mohammed Younes
UPDATE 1
Problem: I needed to have both Anonymous Authentication and Windows Authentication enabled.
But when you enable them both, you can only get NT AUTHORITY\IUSR.
Resolution: To get the current user (introduced with NTLM prompt), we need to create an handler that will execute when an user enter at login page.
When the user hits the login page, the handler will get the current windows identity cached in the browser and then set as the LogonUserIdentity.
Note: I needed to use windows first login, when the user hits the login page it will try to get the correspondent ASP.NET User.

Note
You need to have AccountController.cs as partial.

using System.Web;
using System.Web.Mvc;
using System.Web.Routing;
using Microsoft.AspNet.Identity;

var user = UserManager.Find(loginInfo);

{

return RedirectToLocal(returnUrl);
}
else
{
return RedirectToAction("Login", new RouteValueDictionary(new { controller = "Account", action = "Login", returnUrl = returnUrl }));
}
}
//

#region helpers
private UserLoginInfo GetWindowsLoginInfo()
{
if (!Request.LogonUserIdentity.IsAuthenticated)
return null;
return new UserLoginInfo("Windows", Request.LogonUserIdentity.User.ToString());
}
#endregion
}
public class WindowsLoginConfirmationViewModel
{
[Required]
[Display(Name = "User name")]
public string UserName { get; set; }
}
}
Then, you need to add the handler:
<add name="Windows Login Handler" path="Login" verb="GET,POST" type="MixedAuth.WindowsLoginHandler" preCondition="integratedMode" />
Startup.cs
app.CreatePerOwinContext(dbEmployeePortal.Create);
app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
app.CreatePerOwinContext<ApplicationSignInManager>(ApplicationSignInManager.Create);
PathString path = new PathString("/Account/Login");
if (GlobalExtensions.WindowsAuthActive)
path = new PathString("/Windows/Login");
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
//LoginPath = new PathString("/Account/Login")
LoginPath = path
});
// Use a cookie to temporarily store information about a user logging in with a third party login provider
app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
Then you need to configure Local IIS to use WindowsAuthentication and AnonymousAuthentication. You can do this in the Authentication Module.
Note If you don't have WindowsAuthentication go to Control Panel then Programs and Features then "Turn Windows features on or off":
select "Internet Information Services" > "World Wide Web" > "Security"
and select Windows Authentication.

I didn't see this in your answer, so for anyone looking on how to capture Windows Auth in your Owin pipeline, you also can add the following to your ConfigureAuth method:
public void ConfigureAuth(IAppBuilder app)
{
HttpListener listener = (HttpListener)app.Properties["System.Net.HttpListener"];
listener.AuthenticationSchemes = AuthenticationSchemes.IntegratedWindowsAuthentication;
}

Asp.net Identity + Unit of Work: Getting duplicated entries

I am using the newest version of ASP.NET Identity, using the sample project as a base template.
My changes are simple: Adding a FIRM Properyt to the application user.
Thus, the application User looks like this:
public class ApplicationUser : IdentityUser
{
/// <summary>
/// Gets or sets the firm.
/// </summary>
/// <value>
/// The firm.
/// </value>
public virtual Firm Firm { get; set; }
/// <summary>
/// Generates the user identity asynchronous.
/// </summary>
/// <param name="manager">The manager.</param>
/// <returns>A claims identity</returns>
public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
{
//// Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
//// Add custom user claims here
return userIdentity;
}
}
Also, I do have a Unit Of Work implented, which is responsible for Firm and other entities.
/// <summary>
/// This contains a Unit of Work pattern Implementation. Provides access to all Elements used in this Application.
/// </summary>
public class UnitOfWork : IDisposable, IUnitOfWork
{
/// <summary>
/// The database context
/// </summary>
private PriorityDBContext dbContext = new PriorityDBContext();
public UnitOfWork(ApplicationDbContext dbContext)
{
this.dbContext = (PriorityDBContext)ApplicationDbContext;
}
private GenericRepository<Firm> firmRepository;
public IGenericRepository<Firm> FirmRepository
{
get
{
if (this.firmRepository == null)
{
this.firmRepository = new GenericRepository<Firm>(this.dbContext);
}
return this.firmRepository;
}
}
}
Now to my problem: I have an Account Controller, which can create new Users (among other things). When a new User is created, the Firm is silently doubled. E.g. I had a Firm called "Example1" in the database before. Now I create a new User and suddenly the Database contains "Example1" two times.
As far I can tell, the root cause is that Asp.net Identity uses one DbContext, my UnitOfWork another. I am unsure why, I tried to set up Ninject in a way that the same DbContext is used in all parts. But it simply have enormous problems getting the same db Context into the UserManager and the unit of work :(

this.uoW = uow;

{
get
{
if (this.userManager == null)
{
this.userManager = HttpContext.GetOwinContext().GetUserManager<ApplicationUserManager>();
}
return this.userManager;
}

this.userManager = value;
}
}

public async Task<ActionResult> Register(RegisterViewModel model)
{
bool success = true;

var user = new ApplicationUser { FirstName = newUser.FirstName, LastName = newUser.LastName, Email = newUser.Email, UserName = newUser.Email, PreferredLanguage = newUser.Language, Firm = firm };
var password = Guid.NewGuid().ToString();
var result = await this.UserManager.CreateAsync(user, password);
if (result.Succeeded)
{
this.logger.Info("Created user for {0} successfully", newUser.Email);
}
}
}
}
}
}
Ninject, registering the Bindings:
private static void RegisterServices(IKernel kernel)
{
/// loading the ApplicationDbContext here because the UserManager uses it from the OwinContext and if the
/// Unit of Work defines it's own DBContext, bad things happen, e.g. duplicated objects when working with users AND our own pocos here.
kernel.Bind<IUnitOfWork>().To<UnitOfWork>().WithConstructorArgument("dbContext", ninjectContext => HttpContext.Current.GetOwinContext().Get<ApplicationDbContext>());
kernel.Bind<IGenericRepository<Firm>>().To<GenericRepository<Firm>>();
//kernel.Bind<ApplicationUserManager>().To(HttpContext.Current.GetOwinContext().GetUserManager<ApplicationUserManager>());
}
The ApplicationUserManager:
public class ApplicationUserManager : UserManager<ApplicationUser>
{
public ApplicationUserManager(IUserStore<ApplicationUser> store)
: base(store)
{
}
public static ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options, IOwinContext context)
{
var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(context.Get<ApplicationDbContext>()));
//// Konfigurieren der Überprüfungslogik für Benutzernamen.
manager.UserValidator = new UserValidator<ApplicationUser>(manager)
{
AllowOnlyAlphanumericUserNames = false,
RequireUniqueEmail = true
};
// snipped
return manager;
}
}

How do I NOT use DependencyResolver.Current.GetService(...) in this situation

Following the advice I have been given in this thread [Ninject UOW pattern, new ConnectionString after user is authenticated I now understand that I should not use the following line...
var applicationConfiguration =
(IApplicationConfiguration)
DependencyResolver.Current.GetService(typeof(IApplicationConfiguration));
...as a Service Locator is an anti-pattern.
But in the case of the following procedure how can I instantiate my concrete object that implements "IApplicationConfiguration" so that I can use that object to get the unknown user role name, or use it to assign to the "ApplicationConfiguration" property of my principle?

I am using Ninject as my Dependency Injection framework. Any suggestions appreciated.
EDIT: Full code can be seen here:

You can't prevent having to call either the DI Container or an abstraction over it in your Application_PostAuthenticateRequest, but that shouldn't be a problem, since this Application_PostAuthenticateRequest can be considered to be part of your Composition Root. Or in other words: you have to resolve it somewhere.
The problem in your case, however, is that this method contains an awful lot of code, and the real problem is that you are missing an abstraction. To resolve this, extract all logic of this method into a new class and hide it behind an abstraction. What will be left is the following code:
protected void Application_PostAuthenticateRequest(Object sender, EventArgs e)
{
var provider = (IPostAuthenticateRequestProvider)
DependencyResolver.Current.GetService(typeof(IPostAuthenticateRequestProvider));
provider.ApplyPrincipleToCurrentRequest();
}
The code can be built up by your DI Container, and will have the following signature:
public class MvcPostAuthenticateRequestProvider : IPostAuthenticateRequestProvider
{
private readonly IApplicationConfiguration configuration;
public MvcPostAuthenticateRequestProvider(IApplicationConfiguration configuration)
{
this.configuration = configuration;
}
public void ApplyPrincipleToCurrentRequest()
{
// ...
}
}

Following Steven's suggestion, the final code was:
A new interface "IPostAuthenticateRequestProvider"
/// <summary>
/// Defines the expected members of a PostAuthenticateRequestProvider
/// </summary>
internal interface IPostAuthenticateRequestProvider
{
/// <summary>
/// Applies a correctly setup principle to the Http request
/// </summary>
/// <param name="httpContext"></param>
void ApplyPrincipleToHttpRequest(HttpContext httpContext);
}
A concrete class that implements "IPostAuthenticateRequestProvider"
/// <summary>
/// Provides PostAuthenticateRequest functionality
/// </summary>
public class MvcPostAuthenticateRequestProvider : IPostAuthenticateRequestProvider
{
#region Declarations
private readonly IApplicationConfiguration _configuration;
#endregion
#region Constructors
public MvcPostAuthenticateRequestProvider(IApplicationConfiguration configuration)
{
_configuration = configuration;
}
#endregion
#region IPostAuthenticateRequestProvider Members
/// <summary>
/// Applies a correctly setup principle to the Http request
/// </summary>
/// <param name="httpContext"></param>
public void ApplyPrincipleToHttpRequest(HttpContext httpContext)
{
// declare a collection to hold roles for the current user
String[] roles;
// Get the current identity
var identity = HttpContext.Current.User.Identity;
// Check if the request is authenticated...
if (httpContext.Request.IsAuthenticated)
{
// ...it is so load the roles collection for the user
roles = Roles.GetRolesForUser(identity.Name);
}
else
{
// ...it isn't so load the collection with the unknown role
roles = new[] { _configuration.UnknownUserRoleName };
}
// Create a new WebIdenty from the current identity
// and using the roles collection just populated
var webIdentity = new WebIdentity(identity, roles);
// Create a principal using the web identity and load it
// with the app configuration
var principal = new WebsitePrincipal(webIdentity)
{
ApplicationConfiguration = _configuration
};
// Set the user for the specified Http context
httpContext.User = principal;
}
#endregion
}
And in global.asax...
public class MvcApplication : NinjectHttpApplication
{
/// <summary>
/// Handles the PostAuthenticateRequest event of the Application control.
/// </summary>
/// <param name="sender">The source of the event.</param>
/// <param name="e">The <see cref="EventArgs"/> instance containing the event data.</param>
protected void Application_PostAuthenticateRequest(Object sender, EventArgs e)
{
// Get a PostAuthenticateRequestProvider and use this to apply a
// correctly configured principal to the current http request
var provider = (IPostAuthenticateRequestProvider)
DependencyResolver.Current.GetService(typeof(IPostAuthenticateRequestProvider));
provider.ApplyPrincipleToHttpRequest(HttpContext.Current);
}
