.NET Core Dependency Injection with constructor parameters

This post will be short and sweet, albeit one that caused me a bit of a headache. I recently worked on an ASP.NET Core project and I wanted to take advantage of the built-in Dependency Injection service to inject various services to the controllers. However, one of the services required a parameter in the constructor. This is not highly unusual so I was expecting to quickly find an example in the official docs, explaining how to do this. My search, however, returned no results. I then turned to Google/Bing but guess what? Nothing. Every example I found re-iterated …[read more]


Securing ASP.NET Core application settings using Azure Key Vault

Azure Key Vault is one of my favourite services, competing for first place with Azure Functions. And .NET Core is my favorite framework for writing applications. Imagine, then, my suprise when I found out that my favorite tools can now work together! Azure Key Vault is a cloud service for storing sensitive "secrets" and (encryption) "keys". Key Vault is simple, easy and indispensible when developing secure applications. It helps avoid the complexity of storing sensitive information in configuration files. This can be API passwords, database connections strings etc. You get the point! Previous solutions where convoluted and complex and often …[read more]


ASP.NET Core from the command line

ASP.NET Core (formerly known as ASP.NET 5 or vNext) runs on top of the new DotNet Core and is in love with the command line. Although Visual Studio 2015 is still an excellent IDE and Visual Studio Code an amazing code editor, the new iteration of ASP.NET is equally powerful with the command line. ASP.NET Core 1.0 hit RTM on June 27th, however the tooling around it is still in Preview. Things are still changing, mainly because there's still work to be done around the csproj/project.json migration and dotnet native. How to install …[read more]


Using environment variables for application configuration settings

Configuration settings is always a thorny subject. That's because different developers have different preferences on how to do this. In the .NET world, you have the app.config and web.config depending on the project type. Then you can also use ConfigR or even static XML/JSON files. Another option is to store these settings in the database. There's is no right or wrong answer and you should use whatever works best. However, I recently started working with a new team, where things are not as straightforward when it comes to configuration settings. The application is a standard ASP.NET …[read more]


ASP.NET MVC WebAPI - Optional parameters

ASP.NET WebAPI is a powerful tool for creating APIs quickly and efficiently in .NET. In fact, it takes minimal effort to expose your data through WebAPI though this is both a curse and a blessing. Blessing because it's so easy, curse because you need to be very careful of what you expose. You need to ensure that you're not exposing unwanted information and only provide authenticated access when necessary. Securing WebAPI is a big subject so I'll leave that for another post. Today, I'll show you how to create WebAPI controller methods that take optional parameters. 1. Using default …[read more]
