(Parameter 'configure') in startup when configuring services.AddMvc(). According to Microsoft ( https://docs.microsoft.com/en-us/dotnet/core/compatibility/aspnetcore ) a breaking change AddAuthorization overload moved to different assembly may be the cause The sample code requires the configuration via the setupAction parameter, that's why it's not allowed to pass null which is verified. In case the configuration is optional, it is common with .NET Core to define the setupAction parameter as optional with a default value null.

You have a ASP.NET Core web project and you are using the built-in IoC container of ASP.NET Core to register and resolve your dependencies. Things looks good and perfect, ASP.NET Core framework. The Null Object Pattern is a pattern that uses objects with null behavior instead of performing null checks throughout the codebase. ILogger and ILoggerFactory are dependencies that often require a lot of null checking, so they are perfect candidates for the null object pattern. Suppose your classes take ILogger or ILoggerFactory as a dependency, and you are not using the null object pattern.

WRN: Assembly binding logging is turned OFF. To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1. Note: There is some performance penalty associated with assembly bind failure logging. To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] Azure Functions have had native IoC since V2 — the official Microsoft documentation is quite well written and simple to follow along..

If you've built applications using ASP.NET Core then you've most likely used the built-in dependency injection container from Microsoft.Extensions.DependencyInjection.This package provides an implementation of the corresponding abstractions found in Microsoft.Extensions.DependencyInjection.Abstractions.. In this post, I wanted to take a deeper look at the first concept from the Microsoft. This post looks at the GetService<T>() and GetRequiredService<T>() methods of the default/built-in ASP.NET Core DI container, provided in Microsoft.Extensions.DependencyInjection.I'll describe the differences between them and which one you should use. tl;dr GetService() returns null if a service does not exist, GetRequiredService() throws an exception instead

TIP: Even though the ASP.NET Core integration packages take a dependency on the Simple Injector core library, prefer installing the the core library explicitly into your startup project. The core library uses an independent versioning and release cycle. Installing the core library explicitly, therefore, gives you the newest, latest release (instead of the lowest compatible release), and allows.

  4. Personally, I'd recommend using Couchbase.Extensions.DependencyInjection to register onto DI. It has the concept of an INamedBucketProvider interface.

.NET Core Dependency Injection with Configuration - csharp ..

Azure App configuration is an amazing service that we have been using in our project to centralize our configuration. If you are unfamiliar with the service I suggest reading Azure App Configuration: an introduction by @rickvdbosch.. We were really happy to move our apis to App Configuration in combination with Azure Key Vault references, this meant that we centralized our configuration. I've been trying to figure out the best way to provide access to connections in my services via Dependency Injection (DI) for a while now. Typically I'll pass the IConfiguration object through to the service using DI and then retrieve the connection string directly and create a new connection object from it like so For a method, if we want to provide multiple roles access, we can either add the AuthorizeAttribute attribute multiple times or provide a comma-separated list of roles for the AuthorizeAttribute attribute.. For our application, the administrator (warehouse manager) role, as well as the user role, both can access the GET method of the InventoryController class When designing code you often end up expecting parameters to be not null but end up checking for null to avoid a NullReferenceException. As you already know, all reference types in C# can take the value of null. Value types like int and boolean cannot take a value of null unless explicitely specified using the nullable value type (int? or. From a terminal window inside VS Code, install the latest version of the Microsoft.Azure.Webjobs.Extensions package (3.0.6) using the code snippet on this site.

While building my console applications I want to be able to use UserSecrets. Just like I can in an ASP Core application.

If a program was calling MyService it still can do it after recompilation because the ILogger is optional. If null is passed for the ILogger, the service still works thanks to the null check operator _logger?
