Zepto is a minimalist JavaScript library for modern browsers with a largely jQuery-compatible API. If you use jQuery, you already know how to use Zepto.

While 100% jQuery coverage is not a design goal, the APIs provided match their jQuery counterparts. The goal is to have a ~5-10k modular library that downloads and executes fast, with a familiar and versatile API, so you can concentrate on getting stuff done.

Moq is a mocking library for .NET Unit Testing (cue the TDD folks reminding us mocks are unnecessary), and it is by far the most widely used mocking library in .NET (475 million downloads vs 87 million for the next largest, NSubstitute). Yesterday, its author released version 4.20.1; which added nagware and a backdoor to Moq, in a bid to drive up paid usages of Moq through ‘Sponsorships’. 

ASP.NET Core in .NET 8 is your complete solution for modern web development. It handles all of your web development needs from the frontend to the backend. You can build beautiful, richly interactive web experiences with Blazor, and high-performance backend APIs and services that are reliable and secure. ASP.NET Core in .NET 8 is perfect for building cloud-native apps, and great tooling in Visual Studio and Visual Studio Code supercharges your productivity. With ASP.NET Core in .NET 8, every developer is a full stack developer! 

The long road to C# 9 has already begun and this is the first article in the world about the C# 9 Candidate features. Once you have completed reading this article, you will hopefully be better prepared for the new C# challenges you will meet in the future. 

• Fixed known issue: The debugger's worker process (msvsmon.exe) unexpectedly exited. Debugging will be aborted.

We’re excited to announce the release of .NET Core 3.0. It includes many improvements, including adding Windows Forms and WPF, adding new JSON APIs, support for ARM64 and improving performance across the board. C# 8 is also part of this release, which includes nullable, async streams, and more patterns. F# 4.7 is included, and focused on relaxing syntax and targeting .NET Standard 2.0. You can start updating existing projects to target .NET Core 3.0 today. The release is compatible with previous versions, making updating easy. 

• Modal progress dialog stays open permanently even when IDE is responsive ('Preparing Solution', 'Creating Project', Edit and Continue, etc).
• PackageId:OpenJDKV1;PackageAction:Uninstall;ReturnCode:0;.

• MSBuild failure when executing multi-line Exec commands.
• You can now use Time Travel Debugging with the snapshot debugger on ASP.NET Apps running on an Azure VM. Please note that this feature may not work in all Azure regions at release. 

.NET Core, the reinvention of the Microsoft .NET Framework as an open source, cross-platform development choice, is a key focus of the upcoming features planned for the Visual Studio IDE.

In conjunction with .NET Standard -- a spec detailing what .NET APIs should be available on all .NET implementations -- .NET Core retains compatibility with .NET Framework, Xamarin and Mono while letting developers use Windows, macOS or Linux machines to code for mobile, cloud and embedded/IoT projects.

While still primarily driven by Microsoft dev teams, .NET Core is hosted on a GitHub repository and is supported by the .NET Foundation, an independent organization created by Microsoft three years ago to improve its open source development and collaboration.

Peeking at the Visual Studio Roadmap (updated last week) reveals .NET Core figures prominently in upcoming functionality for the IDE, both in the near-term and long:  

• Support IE 7+ for textarea.
• Supports HTML5 contentEditable elements (NOT including IE 8)
• Can listen to any character and not just '@'. Can set up multiple listeners for different characters with different behavior and data
• Listener events can be bound to multiple inputors.
• Format returned data using templates
• Keyboard controls in addition to mouse
  • Tab or Enter keys select the value
  • Up and Down navigate between values (and Ctrl-P and Ctrl-N also)
  • Right and left will re-search the keyword.
• Custom data handlers and template renderers using a group of configurable callbacks
• Supports AMD
