Web API 2 security extensibility points part 1: starting point and HTTP request context


Web API 2 comes with a number of new security features. In this new series we’ll concentrate on the HTTP request context and its Principal property. In particular we’ll see how to hook into the different extensibility points in the Web API. These extensibility points offer you to plug in your security-related checks at different points in the application lifetime when a request hits your API. You can carry out a number of checks and modify the request Principal according to your business rules and needs.

I’m building the demo in Visual Studio 2013. I’m not sure at this point how much the Web API template will change in Visual Studio 2015.

Building a Web API 2 project from scratch using OWIN/Katana .NET Part 5: adding an IoC


In the previous post we transformed the CustomersApi application a little bit. We added a customer repository and a customer service. We also transformed the Get action method of CustomersController into an asynchronous one.

We ended up having to construct the dependencies of CustomersController in the constructor like this:

public CustomersController()
	_customerService = new CustomerService(new CustomerRepository());

In this post we’ll get rid of this direct control over the controller dependencies. Instead, we’ll let an ICustomerService object be injected into the controller through its constructor.

Building a Web API 2 project from scratch using OWIN/Katana .NET Part 4: async controllers and mini-DDD


In the previous post we briefly looked at a new hosting project by Microsoft called Helios. It is meant to be the future of web application deployment where Helios removes the necessity of having the entire System.Web dependency in your web project. We saw that Helios is only in a preview state so it shouldn’t be used for real-life projects yet.

In this post we’ll diverge from OWIN/Katana and instead see how we can add asynchronous controller methods to our current CustomersApi web project. We’ll also build a miniature version of a layered application. We’ll put the layers into separate folders for simplicity.

Building a Web API 2 project from scratch using OWIN/Katana .NET Part 1


If you’re a .NET developer then you must have come across the new light-weight web framework standard called OWIN. Its implementation by Microsoft in .NET is called Katana. We’ve looked at OWIN/Katana on this blog already starting here. I won’t go through the same exact same topic in this new series. Instead we’ll concentrate on the basic components that are required at a minimum to build a functioning, platform independent Web API 2 project.

If you’ve read other posts on this blog then you’ll know about my preference for web services as opposed to shiny GUI development á la ASP.NET MVC. Also we’ll be looking into other Web API 2 features in OWIN later on so this will be a good foundation.
