Asp.Net Core WebSockets Vs SignalR. Which should you use? (Full Course)

In this video we build 2 separate chat applications, one using Asp.Net Core WebSockets and the other using SignalR, allowing you to compare approaches and decide on which one works best for you. In both cases we build them with C#, .NET Core and JavaScript. You’ll also learn about:

- .NET Core Request Pipeline
- Request Delegates
- Asynchronous Programming in .NET (Async / Await)
- Introduction to Dependency Injection  

Today, we are shipping .NET 5.0 Release Candidate 1 (RC1). It is a near-final release of .NET 5.0, and the first of two RCs before the official release in November. RC1 is a “go live” release; you are supported using it in production. 

the ASP.NET Core results are almost two times (2x) faster than the Full Framework version.  

Here’s a summary of what’s new in this preview release:

• Request decompression middleware
• Output caching middleware
• Updates to rate limiting middleware
• Kestrel support for WebSockets over HTTP/2
• Kestrel performance improvements on high core machines
• Support for logging additional request headers in W3CLogger
• Empty Blazor project templates
• System.Security.Cryptography support on WebAssembly
• Blazor custom elements no longer experimental
• Experimental QuickGrid component for Blazor
• gRPC JSON transcoding multi-segment parameters
• MapGroup support for more extension methods 

Did you know that when Googlebot is crawling the Web, it runs a version of Chromium behind the scenes and actually runs your JavaScript? This means there are some things to be aware of. 

In the confusing jungle of transpiler languages for JavaScript, there are some gems. TypeScript is mainstream, ReScript is starting to establish itself, and Elm is still an insider tip. This article takes a detailed look at ReScript – but also sheds light on the limitations of the young language. In what projects does its use make sense? What projects should rather use TypeScript on the one hand or Elm on the other? 

It’s ~90 pages of step-by-step instructions with screenshot on how to set up Windows Server 2016, SQL Server 2017, Team Foundation Server 2018, and a TFS2018 build server.
