PostSharp 6.0 is the biggest refactoring since the 2.0 version released in July 2010. For a good cause: PostSharp 6.0 now runs natively in .NET Core 2.0. Previous versions of PostSharp executed only under .NET Framework at build time and the support for .NET Core was achieved by using a load of hacks that ended up being unmaintainable, warranting this big refactoring.

Let’s have a look at the new features of PostSharp 6.0 :

• Support for .NET Core 2.0-2.1 and .NET Standard 2.0.
• Support for Portable PDB.
• Support for C# 7.2.
• Ending the PostSharp versioning hell side-by-side: backward compatibility within the same major version.
• Logging: robustness to faults in the logging subsystem.
• Logging: no need to initialize before the first logged method is hit.
• Caching: preventing concurrent execution (locking).
• Visual Studio tooling: support for the new CPS-based project systems.
• GDPR compliance: we no longer collect your name and email for trial, nor use unsecure HTTP, nor use non-resettable user id hashes. 

Bogus is a simple fake data generator for .NET languages like C#, F# and VB.NET. Bogus is fundamentally a C# port of faker.js and inspired by FluentValidation's syntax sugar. 

You don't need Axios, well, for most use cases. The web is maturing, and the days of Axios are ending. 

Today we are glad to announce an alpha release of SignalR for ASP.NET Core 2.0. This is the first official release of a new SignalR that is compatible with ASP.NET Core. It consists of a server component, a .NET client targeting .NET Standard 2.0 and a JavaScript/TypeScript client. 

A function for loading CSS asynchronously

Why loadCSS?

Referencing CSS stylesheets with link[rel=stylesheet] or @import causes browsers to delay page rendering while a stylesheet loads. When loading stylesheets that are not critical to the initial rendering of a page, this blocking behavior is undesirable. The new <link rel="preload"> standard enables us to load stylesheets asynchronously, without blocking rendering, and loadCSS provides a JavaScript polyfill for that feature to allow it to work across browsers. Additionally, loadCSS offers a separate (and optional) JavaScript function for loading stylesheets dynamically.

Channels are a construct that simplifies concurrent execution and pipelining of data and is often touted as one of the main draws of Go. But did you know that .NET also has built-in support for channels? 

Tap is a Javascript library for easy unified handling of user interactions such as mouse, touch and pointer events.

• No need to detect what kind of events are supported, Tap handles this for you
• Small distribution size of 1Kb
• Use fastest event types supported (majority of browsers has ~300ms delay between touch/pointer events and click). Every millisecond does really matter!

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).
