The future of C#
Over the last year we shipped no less than three "point releases" of C# (7.1, 7.2 and 7.3), full of small but useful language features. Mads and Dustin will race you through a tour of these, before turning to some of the big things we have in store for the future: Nullable reference types, recursive patterns, asynchronous streams and more. 

This is a practical guide for implementing Domain Driven Design (DDD). While the implementation details are based on the ABP Framework infrastructure, the basic concepts, principles and models can be applied to any solution, even if it is not a .NET solution.

An Introduction to .NET MAUI For Mobile Development

.NET Multi-platform App UI (.NET MAUI) is a cross-platform framework for creating native mobile and desktop apps with C# and XAML.
.NET MAUI is open-source and is the evolution of Xamarin.Forms, extended from mobile to desktop scenarios, with UI controls rebuilt from the ground up for performance and extensibility. If you've previously used Xamarin.Forms to build cross-platform user interfaces, you'll notice many similarities with .NET MAUI. However, there are also some differences. Using .NET MAUI, you can create multi-platform apps using a single project, but you can add platform-specific source code and resources if necessary. One of the key aims of .NET MAUI is to enable you to implement as much of your app logic and UI layout as possible in a single code-base.

• Separated the existing "Restore Packages" option in the Command Palette into two distinct functions:

  • "Restore Project" - Displays a drop-down that shows all the available projects in the solution or in the workspace. Selecting one of them would trigger a dotnet restore for the particular project.
  • "Restore All Projects" - Triggers a dotnet restore for all projects in the current solution or workspace.
   

Third Party Site Cookies

In August 2020, Google announced their 'Privacy Sandbox' initiative, which aims to preserve and protect user's privacy. The cookie processing change is part of this initiative. An official  blog post sheds some light on it.

Google will drop support for third-party cookies in the Chrome browser in two years. Also, the company will start limiting cross-site tracking by enforcing its new SameSite rules . This has already happened in Chrome 80.

The SameSite-by-default and SameSite=None-requires-Secure behaviors will begin rolling out to Chrome 80 Stable for an initial limited population starting the week of February 17, 2020. 

Fixed In This Release of Visual Studio 2019 version 16.5

• Modified the find "List View" to work with the VsColorOutput extension.
• Fixed a regression introduced with version 16.5 where use of default indexed properties with value-types caused an internal compiler error.
• Modified find in files to preserve user settings between Visual Studio 2019 sessions.
• Fixed an issue where Goto next/previous entry failed to work in the find results list when "preview selected files in find results" is turned off.
• Fixed an issue with find when doing a regex search a pattern that did not contain regex special characters.
• Fixed the button placement in find in files tool window when its in a docked position. Changed alignments for better experience in docked mode.
• Fixed an issue where the find list view did not navigate to results when enter was hit.
• Fixed an issue where Goto next/previous entry failed to work in the find results list when "preview selected files in find results" is turned off.
