Part 1 took an overview of the initial design of ASP.NET and how Microsoft reacted to the various changes in webdev. In Part II, we will now look at how those changes influenced the development of ASP.NET MVC and ended up transforming ASP.NET into a much more flexible framework composed of multiple libraries that solved different problems.

I’ve been building some ASP.NET Core apps as of late and had to dig into how Dependency Injection works there. After talking with Julie Lerman a bit on Twitter about it, I realized that there might be some confusing things about how it works in ASP.NET Core, so I’m hoping I can add some clarity in this post. 

In this post, I'll describe how controllers are created in ASP.NET Core MVC using the IControllerActivator, the options available out of the box, and their differences when it comes to dependency injection. 

How To Use:

//In Startup.cs:
    
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvcCore(options =>
        {
            options.ModelBinderProviders.Insert(0, new PersianDateModelBinderProvider());
        });
    }

//In Actions:
    
     public async Task<IActionResult> SampleAction(DateTime birthDate)
        {
            if (ModelState.IsValid)
            {
                //birthDate is valid
            }
            else
            {
                birthDate is wrong
            }

            ...
        }

highlights the capabilities of the In-memory technology, showcasing the awesome performance gains as well as how easy it is to get started with and use In-memory OLTP.
