Practical C# Design

Learn about object-oriented and functional programming using C# and .NET. Improve your skills while avoiding pitfalls and common mistakes.
Videos in this list are covering C# syntax, coding practices and patterns applied in object-oriented and functional design. 

This is a (non-comprehensive) guide for C# and .NET developers that are completely new to the Rust programming language. Some concepts and constructs translate fairly well between C#/.NET and Rust, but which may be expressed differently, whereas others are a radical departure, like memory management. This guide provides a brief comparison and mapping of those constructs and concepts with concise examples. 

The Bosque programming language is designed for writing code that is simple, obvious, and easy to reason about for both humans and machines. The key design features of the language provide ways to avoidaccidental complexity in the development and coding process. The goal is improved developer productivity, increased software quality, and enabling a range of new compilers and developer tooling experiences.

As a relatively new framework, there's probably a lot you don't know about Blazor yet. Here are 10 great features about Blazor you should know. 

"If you rely on legacy features in WCF, ASPX pages, or other older technologies then they likely don't have any path forward after framework 4.8."  

Your audience wants a fast website. Don't disappoint them. In today's post, I cover ten ways to speed up your ASP.NET MVC application. 

Microsoft has shifted .NET's focus from Windows to " the cloud" (code for Azure). If you don't care about Azure then there's nothing really exciting in all these changes.
