How to use TinyIoC in ASP NET Core

With ASP.NET Core MVC, the tradition of ASP.NET MVC continues into today’s version of the framework. The Web Forms approach allowed experienced Windows developers to program dynamic web pages. This process meant that the web’s underlying mechanisms were hidden from developers; they could continue to use workflows and development environments with which they were familiar. More specifically, Microsoft-specific visual rapid application development (RAD) tools were used. The basic functionality of ASP is roughly comparable with PHP or the “Java Server Pages” (JSP).

ASP.NET Core middleware performs asynchronous logic on an HttpContext and then either invokes the next middleware in the sequence or terminates the request directly. You generally “Use” middleware by taking a dependency on a NuGet package and invoking a corresponding UseXYZ extension method on the IApplicationBuilder in the Configure method. The first preview release of ASP.NET came out almost 15 years ago as part of the .NET Framework. Since then millions of developers have used it to build and run great web apps, and over the years we have added and evolved many capabilities to it.

New programming models in ASP.NET Core

It was possible to use other web servers with “Mon” as a free .NET implementation. However, the real change came with the release of .NET Core and the “Open Web Interface for .NET” (OWIN). OWIN dissociates an ASP.NET application from the underlying web server. The biggest advantage of ASP.NET – the use of the Microsoft-specific ecosystem – is also its main disadvantage. That’s because web development is otherwise largely built on free and open platforms, languages, and formats.

  • When the managed code is compiled, the compiler converts the source code into a CPU independent intermediate language (IL) code.
  • It provides server side controls and events to create web application.
  • This puts ASP.NET Core on par with JavaScript-based frameworks such as React.
  • It provides fantastic integration of HTML, CSS and JavaScript.
  • It is the technology used for working with data and databases.

Note how the type has been passed to retrieve the appropriate type of object from the container. You can now use this instance (named _myService) to invoke methods pertaining to the IMyService interface. You can now invoke the RegisterDependencies method of the Bootstrap class to register the services with the built-in container of the ASP.NET Core runtime as shown below. In this example, we’ll create a minimalistic class which we’ll use as a dependency in the API controller we’ll create later. To do this, create a new class named MyService and replace the generated code with the following code listing.

Why build ASP.NET Core?¶

You can optionally provide a name when registering the service with the container as shown in the code snippet given below. Because we’re working with .NET Core, we should use the TinyIoC Release Candidate NuGet package. You should check the “Include prerelease” check box in the “Manage NuGet Packages…” window and install the latest TinyIoC RC NuGet package version as shown in Figure 1 below. To use the code examples provided in this article, you should have Visual Studio 2022 installed in your system.

Main uses WebHostBuilder, which follows the builder pattern, to create a web application host. The builder has methods that define the web server (for example UseKestrel) and the startup class (UseStartup). In the example above, the Kestrel web server is used, but other web servers can be specified. WebHostBuilder provides many optional methods including UseIISIntegration for hosting in IIS and IIS Express and UseContentRoot for specifying the root content directory. The Build and Run methods build the IWebHost that will host the app and start it listening for incoming HTTP requests. The inversion of control (IoC) and dependency injection (DI) architectural patterns help you enhance the modularity, testability, and maintainability of your application.

Furthermore, some components were redeveloped and retained their existing names. For example, the SignalR Framework exists in both ASP.NET and ASP.NET Core versions. Let’s take a look at the main new developments of ASP.NET Core. Implementing a complete solution with all the details you’ve requested involves a significant amount of code, and it might not be feasible to provide an exhaustive example here.

The code that is directly managed by the CLR is called the managed code. When the managed code is compiled, the compiler converts the source code into a CPU independent intermediate language (IL) code. A Just In Time(JIT) compiler compiles the IL code into native code, which is CPU specific. These can be hosted on a variety of server environments in addition to IIS.

Inversion of control and dependency injection

Most IoC containers consume a lot of resources—not ideal when you don’t need a full-fledged IoC container in your application. Classic Web Forms are used to assemble pages from predefined components. Here, a visual form builder is used that allows individual components to be positioned by drag-and-drop. This was particularly attractive for developers with experience in Windows programming. They could use the tools they were familiar with for “Rapid Application Development” (RAD).

With ASP.NET Core MVC, functionalities of ASP.NET MVC and ASP.NET Web API have been combined. This enables the development of highly dynamic web applications with a modular user interface and underlying API. Familiar approaches what is asp net from .NET API development can be transferred to MVC development and vice versa. For cases where application logic is less important than a sophisticated layout and design, ASP.NET Web Pages are a good choice.


The web root of your app is the directory in your project for public, static resources like css, js, and image files. The static files middleware will only serve files from the web root directory (and sub-directories) by default. The web root path defaults to /, but you can specify a different location using the WebHostBuilder. In ASP.NET Core you compose your request pipeline using Middleware.

The integrated Kestrel web server is used, which runs on Windows, Linux, and macOS. Popular web servers such as Nginx and Apache can be configured as reverse proxies in conjunction with Kestrel. On Windows, the Kestrel alternative HTTP.sys is also available.

On Windows, ASP.NET Core is built on top of the .NET Framework; on other operating systems, the .NET Core Framework is used instead. Create a new API controller and replace the generated source code with the following code listing. The complete source code of the Program.cs file is given below for your reference. If you have multiple dependencies to register with the container, you can write them inside a method and then call it here once to ensure that the code is clean. Next add the TinyIoC NuGet package to the Web API project you just created in Visual Studio.
