This book is a collection of problems on the knowledge of the .NET platform and the C# programming language 

jQuery 3.7.0 is now available! This release has it all: bug fixes, a new method, and a performance improvement! We even dropped our longtime selector engine: Sizzle. Or, I should say, we moved it into jQuery. 

Today is the official GA release for .NET 5, and along with it we are excited to share the latest updates with our recent release of C#/WinRT version 1.0. C#/WinRT provides WinRT projection support for .NET 5 based apps. The Windows SDK leverages this technology and is now integrated with the .NET 5.0 SDK to expose Windows APIs through the new Target Framework Monikers. In addition to the Windows SDK support added for .NET 5, C#/WinRT itself allows component authors to build their own .NET 5 projections using the CsWinRT NuGet package.  

Daniel Roth overviews ASP.NET 5 and ASP.NET MVC 6. He explains the guiding principles behind ASP.NET MVC 6, and overviews application development, pointing out some important new features in both ASP.NET MVC and Web API 

There are two MySQL providers for Entity Framework Core:
- The official one from MySQL: MySql.Data.EntityFrameworkCore. As of now, the latest version is 8.0.19, and works with Entity Framework Core 2.1 (and probably also 2.2). Since EF Core 3.0 is a major version with breaking changes, you cannot use it with this provider.
- The Pomelo provider: Pomelo.EntityFrameworkCore.MySql. There is a 3.1 version of this provider.
In other words, if you want to use EF Core 3.0/3.1 with MySQL, at this point you need to use the Pomelo provider (or wait for the official MySQL one to get released).

While Classic ASP is almost dead , and ColdFusion is a high-end niche tool, PHP coming third, is actually leading the ranking. 

The biggest improvement for runtime debugging is Edit & Continue for XAML apps. 

, What Every JavaScript Developer Should Know About ECMAScript 2015 is the book I'd like to read about the new features in the JavaScript language. The book isn't a reference manual or an exhaustive list of everything in the ES2015 specification. Instead, I purposefully selected what I think are the important features we will use in everyday programming.  

For a good and secure web – and also for faster performance, new APIs on the web such as Service Workers, better search ranking and more – using HTTPS for your web site is key. I’ll walk you through how to easily get started with that here.
