Dependency Injection in ASP.​NET Core - a quick overview

With ASP.NET Core Dependency Injection is now a first class citizen in ASP.NET. All parts of the ASP.NET Stack are using the same DI container. In this post I'm going to show you, how to configure the DI container and how to use it.

Blockchain is all about storing and processing sensitive information – like financial transactions or voting records – on lots of different computers, rather than sticking it in all in one place.

Demystifying .NET Core and .NET Standard

This post is a summary of the blog post at MSDN.

Introduction to .NET Core

.NET Core: This is the latest .NET implementation. It’s open source and available for multiple OSes. With .NET Core, you can build cross-platform console apps and ASP.NET Core Web applications and cloud services.

.NET Core is a new cross-platform and fully open source .NET implementation that was forked from .NET Framework and Silverlight. It’s optimized for mobile and server workloads by enabling self-contained XCOPY deployments.

Introduction to .NET Standard

.NET Standard: This is the set of fundamental APIs (commonly referred to as base class library or BCL) that all .NET implementations must implement. By targeting .NET Standard, you can build libraries that you can share across all your .NET apps, no matter on which .NET implementation or OS they run.

When you’re building modern experiences, your app often spans multiple form factors and, therefore, multiple .NET implementations. In this day and age, customers pretty much expect that they can use your Web app from their mobile phone and that data can be shared via a cloud-based back end. When using a laptop, they also want to get access via a Web site. And for your own infrastructure, you likely want to use command-line tools and potentially even desktop apps for letting your staff manage the system.

In such an environment, code sharing becomes a major challenge. You need to understand where APIs are available and make sure that shared components only use APIs that are available across all .NET implementations you’re using.
