Can't resolve IMemoryCache dependency

I have a net.core 3.1 hosted service application. In this app, autofac is used as a DI container in addition to a standard container. I try to adding and use IMemoryCache as following:
In Program.cs
Host.CreateDefaultBuilder(args)
.ConfigureAppConfiguration(...)
...etc
.UseServiceProviderFactory(new AutofacServiceProviderFactory())
.ConfigureServices((hostContext, services) =>
{
// Register configuration
services.AddMemoryCache();
// some another services
}
.ConfigureContainer<ContainerBuilder>(ConfigureContainer)
.UseConsoleLifetime();
ConfigureContainer is a method where some types are registered using autofac.
In my service I add memory cache dependency as following:
public class MyService: IMyService
{
private readonly IMemoryCache _memoryCache;
public MyService(IMemoryCache memoryCache)
{
_memoryCache = memoryCache;
}
}
But I get this exception when application was started:
Autofac.Core.DependencyResolutionException: An exception was thrown while activating λ:Microsoft.Extensions.Hosting.IHostedService[] -> MyNamespace.WorkerService -> MyNamespace.MyAnotherService -> MyNamespace.SomeAnotherService -> MyNamespace.MyService -> Microsoft.Extensions.Caching.Memory.MemoryCache.

I tried register all needed for caching services manually using autofac in ConfigureContainer instead of using .AddMemoryCache() as following (copy paste from .AddMemoryCache() body):
builder.RegisterType(typeof(OptionsManager<>)).As(typeof(IOptions<>)).SingleInstance();
builder.RegisterType(typeof(OptionsManager<>)).As(typeof(IOptionsSnapshot<>));
builder.RegisterType(typeof(OptionsMonitor<>)).As(typeof(IOptionsMonitor<>)).SingleInstance();
builder.RegisterType(typeof(OptionsMonitor<>)).As(typeof(IOptionsFactory<>)).SingleInstance();
builder.RegisterType(typeof(OptionsFactory<>)).As(typeof(IOptionsMonitorCache<>)).SingleInstance();
builder.RegisterType<MemoryCache>().As<IMemoryCache>().SingleInstance();
but in this case I get another exception:
System.ArgumentException: The type 'Microsoft.Extensions.Options.OptionsManager`1[TOptions]' is not assignable to service 'Microsoft.Extensions.Options.IOptions`1'.

Any suggestions?

I found my mistake. Thanks to Sergey, I check my Program.cs and discovered that I use .AddMemoryCache() extension at one time with register IMemoryCache in ConfigureContainer. Only the extension method needs to be used, no manual registration of IMemoryCache needed.

HttpActionContext.get_Request() method not found when using Microsoft Asp.NET Dependency Injection

I am trying to add Microsoft Extensions Dependency Injection to an existing ASP.NET WebApi/Owin project.
Following this blog post, I have added the ConfigureServices function, implemented DependencyResolver, and made HttpConfiguration instance to use it.
Also I added all the non-abstract controllers to DI, and ensured they are instantiated using the DI mechanism.
But after all these actions, requests to the application return error 500 with exception
Method not found: 'System.Net.Http.HttpRequestMessage System.Web.Http.Controllers.HttpActionContext.get_Request()'.
I get the same result even if I just add the Microsoft.Extensions.DependencyInjection package to NuGet and don't change any other code. After I remove it, everything works fine.
Here is the code I added into Startup.cs:
The DependcyResolver implementation:
public class DefaultDependencyResolver :
System.Web.Http.Dependencies.IDependencyResolver,
System.Web.Http.Dependencies.IDependencyScope
{
protected IServiceProvider serviceProvider;
public DefaultDependencyResolver(IServiceProvider serviceProvider)
{
this.serviceProvider = serviceProvider;
}
public IDependencyScope BeginScope()
{
return this;
}
public void Dispose() { }
public object GetService(Type serviceType)
{
return this.serviceProvider.GetService(serviceType);
}
public IEnumerable<object> GetServices(Type serviceType)
{
return this.serviceProvider.GetServices(serviceType);
}
}
Adding controllers to DI:
public void ConfigureServices(IServiceCollection services)
{
System.Diagnostics.Debugger.Launch();
IEnumerable<Type> controllers = typeof(Startup).Assembly.GetExportedTypes()
.Where(t => !t.IsAbstract && !t.IsGenericTypeDefinition)
.Where(t => typeof(IController).IsAssignableFrom(t)
|| t.Name.EndsWith("Controller", StringComparison.OrdinalIgnoreCase));
foreach (var c in controllers)
{
services.AddTransient(c);
}
}
Creating ServiceCollection, calling services configuration and setting DependencyResolver:
public void Configuration(IAppBuilder app) {
// ...
HttpConfiguration httpConfiguration = new HttpConfiguration();
var services = new ServiceCollection();
ConfigureServices(services);
httpConfiguration.DependencyResolver =
new DefaultDependencyResolver(services.BuildServiceProvider());
WebApiConfig.Register(httpConfiguration);
app.UseWebApi(httpConfiguration);
}

You might need to add binding redirects to your web.config file.
Check the following links with more information on the issue:
https://github.com/Microsoft/BotBuilder/issues/3615
https://github.com/dotnet/standard/issues/481
https://learn.microsoft.com/en-us/dotnet/framework/configure-apps/how-to-enable-and-disable-automatic-binding-redirection

I've installed 'System.Net.Http' from nuget (v 4.3.3) and updated my .csproj file to force msbuild to use specified dll:
<Reference Include="System.Net.Http, Version=4.1.1.2, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MSIL">
<HintPath>..\packages\System.Net.Http.4.3.3\lib\net46\System.Net.Http.dll</HintPath>
</Reference>
It resolved the problem.

Structuremap - setup dependency which has dependency

I'm using structure map as my IOC with web api and I have an injected dependency in my controller and it's concrete type also has a dependecy.
Controller
[RoutePrefix("api/products")]
public class ProductsController : BaseApiController
{
//private readonly ProductRepository _manageProducts;
private readonly IProductFactory _productFactory;
private readonly IGenericRepository _genericRepository;
public ProductsController(IProductFactory productFactory, IGenericRepository genericRepository)
{
_productFactory = productFactory;
_genericRepository = genericRepository;
//_manageProducts = new ProductRepository();
}
[Authorize]
[Route("addProduct")]
public IHttpActionResult AddNewProduct(ProductViewModels.AddProductViewModel product)
{
if (User.IsInRole("Admin"))
{
_productFactory.CreateProduct(product);
return Ok("Product Successfully Added");
}
return BadRequest("Your must have Administrator rights to perform the operation.");
}
}
Factory
public class ProductFactory : IProductFactory
{
private readonly IGenericRepository _genericRepository;
public ProductFactory(IGenericRepository genericRepository)
{
_genericRepository = genericRepository;
}
/// <summary>
/// Creates the product.
/// </summary>
/// <returns>The product.</returns>
/// <param name="viewModel">New product.</param>
public Product CreateProduct(ProductViewModels.AddProductViewModel viewModel)
{
var productToBeAdded = new Product
{
Title = viewModel.Title,
ISBN = viewModel.ISBN,
};
return productToBeAdded;
}
}
When I try to call product controller addproducts I get this runtime error for null reference exception:
{
"Message": "An error has occurred.",
"ExceptionMessage": "Object reference not set to an instance of an object.",
"ExceptionType": "System.NullReferenceException",

}
This is what I've done with structuremap
public class DefaultRegistry : Registry
{
#region Constructors and Destructors
public DefaultRegistry()
{
Scan(
scan =>
{
scan.TheCallingAssembly();
scan.WithDefaultConventions();
});
For<IGenericRepository>().Use<GenericRepository<ApplicationDbContext>>();
For<IProductFactory>()
.Use<ProductFactory>()
.Ctor<IGenericRepository>()
.Is<GenericRepository<ApplicationDbContext>>().Named("DefaultInstanceKey");
#endregion
}
}
I thought this would fix it so it knows how to resolve my factory:
For<IProductFactory>()
.Use<ProductFactory>()
.Ctor<IGenericRepository>()
.Is<GenericRepository<ApplicationDbContext>>().Named("DefaultInstanceKey");
But it doesn't work neither. Does anyone know how to fix this?

Just register the two interfaces and their implementations. The framework will resolve the dependencies when resolving the target.
For<IGenericRepository>().Use<GenericRepository<ApplicationDbContext>>();
For<IProductFactory>().Use<ProductFactory>();

ASP.NET Core database configuration with dependency injection issue

I ran in to a problem 6 days ago and i still can't figure it out.
I'm setting up a DBContext using DI:
public void ConfigureServices(IServiceCollection services)
{
// Add framework services.
services.AddDbContext<ApplicationContext>(options =>
options.UseSqlite(Configuration.GetConnectionString("DefaultConnection")));
services.AddMvc();
// Add application services.
services.AddTransient<IEmailSender, AuthMessageSender>();
services.AddTransient<ISmsSender, AuthMessageSender>();
}
The database file path is configurered in the appsettings.json
{
"ConnectionStrings": {
"DefaultConnection": "Data Source=xxxx.db"
},
"Logging": {
"IncludeScopes": false,
"LogLevel": {
"Default": "Debug",
"System": "Information",
"Microsoft": "Information"
}
}
}
And I'm creating a DBContext like this (https://learn.microsoft.com/en-us/ef/core/miscellaneous/configuring-dbcontext)
public class ApplicationContext : DbContext
{
public DbSet<Network> xxxx { get; set; }
public DbSet<NetworkEntry> xxxx { get; set; }
public ApplicationContext(DbContextOptions<ApplicationContext> options)
: base(options)
{ }
}
My controller code:
public JsonResult Index(ApplicationContext db)
{
return Json(db.Networks);
}
It compiles and runs. If I use the other way of configuring the DB, it works 100% problem free:
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
optionsBuilder.UseSqlite("Filename=./blog.db");
}
The problem I'm having:

Any clues?

I have just solved a similar problem. The problem for me was that I'd misunderstood the dependency injection. The context doesn't get passed to the Controller method, but to the Controller's constructor.
public class NetworksController : Controller
{
private readonly ChoirAdminContext db;
public NetworksController(ApplicationContext context)
{
db = context;
}
public JsonResult Index()
{
return Json(db.Networks);
}
}

Using ActionFilterAttribute for model validation

I am trying to use ActionFilterAttribute to validate the model when a call is made to my Web API. I have added the following
public class ValidateModelStateAttribute : ActionFilterAttribute
{
public override void OnActionExecuting(HttpActionContext actionContext)
{
if (!actionContext.ModelState.IsValid)
{
actionContext.Response = actionContext.Request.CreateErrorResponse(
HttpStatusCode.BadRequest, actionContext.ModelState);
}
}
}
I have added standard validators to my model properties and it all works fine. However when I add a custom class level validator it fails with the following error.
A validation attribute of type XXXValidatorAttribute cannot be used to
validate values."

This validator works fine when I invoke it via a unit test using a validation factory. I am not sure why it fails during ModelState validation? What is the difference between the two?
I have the model defined as
I have a model defined as
[CashDetailValidator()]
public sealed class CashDetails : DetailsBase
{
// Reference Number
[ValidatorComposition(CompositionType.Or)]
[NotNullValidator(Negated=true)]
[StringLengthValidator(1, RangeBoundaryType.Inclusive, 16, RangeBoundaryType.Exclusive, MessageTemplate = "Reference number should be between 1 to 16 characters in length.")]
public string RelatedReference { get; set; } ...........................
}}
The composition validator also gives the same error.
