Tips and tricks in C# .NET

Introduction
In the previous post we discussed the basics of value and reference equality. We saw how to evaluate these equality types with the ‘==’ and ‘is’ operators. We also found an important difference between how value and reference types are handled in memory.
In this post we’ll look at another feature related to objects and equality, namely the effects of changing the referenced value.

You can easily add your custom HTTP module to a .NET web application. Here’s an excerpt from the MSDN article referenced in the previous sentence:
“An HttpModule is an assembly that implements the IHttpModule interface and handles events. ASP.NET includes a set of HttpModules that can be used by your application.”

In the previous post we discussed how to use OWIN host to self-host a Web API 2 application. We saw how easy and straightforward it was to install the OWIN hosting package with NuGet.
In this post we’ll look at another hosting option: Helios.

We have looked at implementing IEquatable and overriding various equality-related methods and operators in various other posts on this blog. You can look at this page and scroll down to the section called “Comparison and equality” to view all of them.
In this post we’ll put all of these together and implement a joined equality strategy for our reference type.

We saw how Stacks work in .NET in this post. Stacks are last-in-first-out collections where the last element added to the collection will the first to be removed.
If you’d like to have a Stack that is shared among multiple threads in a multi-threaded application then the “normal” Stack of T object won’t be enough. You can never be sure of the current state of the stack in the very moment when a certain thread tries to pop an item from it. The stack may have been modified by another thread just a millisecond before and then the Pop method will fail. In general you should be very careful with how you share the resources among different threads.

In the previous post we saw how to build a simple Web API from scratch using a couple of OWIN/Katana components. We added a couple of Katana libraries from NuGet, wired up the routing from the Startup class and we were good to go.
In this post we’ll see one way to make the application run independently of IIS. As we stated before an important benefit of this new OWIN infrastructure is that you can make your ASP.NET web application run on multiple hosts, not only IIS. IIS is only one of the options.

Introduction
In the previous post we started discussing the most important cornerstone of object-oriented languages, i.e. objects. We saw how every variable assignment created an object reference in memory with a key, a value and a pointer which points from the key to the value. We also discussed what happens in memory when assigning a value to a variable.
In this post we’ll go through the absolute basics of equality in Python. The notions of value and reference equality are closely related to objects.

In the previous post we looked at how to comment your Python code so that it becomes more understandable. We saw a couple of techniques to write comments and document your code.
In this post we’ll discuss the probably most important ingredient of object-oriented programming languages: objects.

FIFO, that is first-in-first-out, collections are represented by the generic Queue of T class in .NET. Queues are collections where a new element is placed on top of the collection and is removed last when the items are retrieved.
Let’s say that you’re throwing a party where you follow a Queue policy as far as guests are concerned. As time goes by you’d like all of them to leave eventually and the first one to go will be the first person who has arrived. This is probably a most just policy than what we saw in the post on stack collections.

Introduction
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.
