Preventing SQL injection in C# applications

SQL injection is a common attack vector that remains one of the most prevalent security risks for applications today. One of the reasons SQL injection attacks are so pervasive is the fact that injection vulnerabilities are very easy for attackers to discover and exploit, sometimes with devastating consequences. On the other hand, mitigating SQL injection…

How to use tuples with named fields in C# by example

InProgramming

Tuples are a very useful feature of the C# language; they allow more than one value to be grouped and passed back and forth without needing to define additional types. As we’ll discover later in this article, tuples are particularly convenient for returning more than one value from a method, avoiding the need for ugly…

What makes a good device identifier?

InProgramming

Choosing a strategy for calculating a unique and reliable device identifier can be a frustrating and somewhat more difficult decision than you might initially think. There’s no silver bullet and like many things in the world of programming, pros and cons need to be determined and trade-offs need to be made. In this article, I…

How to become a quantum programmer

InProgramming

If like me, you are fascinated by science, you’ll possibly know a little bit already about the strange phenomena of quantum mechanics. Concepts like superposition, entanglement, and teleportation are all things that seem like they should be impossible but have been proven time and time again in the lab. Yes, things do behave very strangely…

How to stop and start IIS websites using C#

InProgramming

IIS (Internet Information Services) remains a widely used web server for hosting websites, FTP (File Transfer Protocol) sites, and other applications on Windows servers. While the graphical IIS Manager interface is great for setting things up initially and for providing a visual overview of your web configuration, there are also some great use cases for…

Implementing an async Repository and Unit of Work with Entity Framework Core

InProgramming

Implementing the Repository pattern in conjunction with the Unit of Work pattern is a best practice for data access that can bring a number of benefits to your application codebase when implemented correctly. Given the ease of use and scalability advantages that async .NET code offers, it makes sense to ensure that your data access…

Monitoring application debug output with DebugView

InProgramming

Once your applications are running in a production environment, it is important to be able to monitor what is happening under the hood. Quite often this is achieved by logging output to a file, to a database, or to some other medium. However, it is also possible to intercept live debug and trace output using…

How to debug a .NET Windows Service from Visual Studio

InProgramming

While developing a Windows Service, it is important to be able to debug it like you would a regular desktop or web application. Debugging Windows Services isn’t quite as straightforward as debugging standard Windows, Console, or Web applications. However, when developing a .NET Windows Service it isn’t difficult to set up your project to support…

How to dynamically load different versions of an assembly in the same .NET application

InProgramming

Have you ever come across the need to use more than one version of an assembly within the same .NET application? Assembly loading can be a somewhat tricky subject when there are multiple versions of the same assembly for a .NET application to choose from. This can result in problems for both static assembly references…

How to download files using C#

InProgramming

Downloading files programmatically is a common task that most programming languages expose different APIs for. I believe it is useful to have examples to refer to for how to accomplish this in your language of choice, both synchronously and asynchronously. This article covers how to download files with C# using the classes and methods that…
