Intro Since we have all been actively celebrating the 20th anniversary of Visual Studio, it felt appropriate to post about C# 7! In this post we will explore the features that make C# 7 so promising. I’ve put together a demonstration C# 7 project, that is available here. This post contains examples and details on five of the nine new C# 7 features. Pattern matching out variables Tuples Local functions throw expressions These are the remaining features, that I do not cover in this post.
Overview In .NET it’s really easy to create your own interfaces and implementations. Likewise, it’s seemingly effortless to register them for dependency injection. But it is not always obvious how to override existing implementations. Let’s discuss various aspects of “dependency injection” and how you can override the “framework-provided services”. As an example, let’s take a recent story on our product backlog for building a security audit of login attempts. The story involved the capture of attempted usernames along with their corresponding IP addresses.
Overview Like the title claims, if you’re using ASP.NET Core and expecting the Thread.CurrentPrincipal or ClaimsPrincipal.Current to be populated you’d be wrong. This is not the IPrincipal you’re looking for. In this post we’ll discuss what happened and what you need to do now. Additionally we’ll cover all the peripheral benefits as a result of this change. History If you have ever done any .NET Framework development, you’ve probably seen the Thread class.
