Working with SecureString in .NET applications

The SecureString class is a .NET type that provides an increased level of security for sensitive in-memory data. Having said that, the security benefits of SecureString have been widely debated. The general consensus is that SecureString can help to increase application security if used properly, however, the inherent advantages are somewhat limited in scope. Despite…

Overcoming dependency injection hurdles with TinyIoC: A lightweight Inversion of Control container

InProgramming

Sometimes when embarking on a software project you may find yourself wishing that you had a lightweight way of achieving Inversion of Control (IoC) via dependency injection. On the other hand, you might not be very familiar with the principle of IoC, but have heard it can be very beneficial and are looking for a…

Preventing SQL injection in C# applications

InProgramming Security SQL

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…

Interacting with MongoDB using C#

InNoSQL

In my previous two posts, I covered how to set up a MongoDB development environment and then followed this up with how to get started with MongoDB queries. While it’s great to have a development environment set up and know how to run queries from the command line, ultimately you’ll need to figure out how…

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…

How to create and load an IdentityServer signing certificate for Azure

InSecurity Web

IdentityServer is the de-facto security token service for ASP.NET and ASP.NET Core web applications and it is hugely popular within the .NET community. One of the most important security requirements to consider when setting up IdentityServer is the creation of a key (typically an X.509 certificate) which is used to cryptographically sign and validate tokens…

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…
