Partial Views and Child Actions are one the most used features of ASP.NET MVC. Partial Views provides us a way to create a reusable component that can be used in multiple Views. There are Actions which can be marked as Child Actions and these cannot be invoked via URL but inside views or partial views. Child Actions are no more available with ASP.NET Core. View Components are new way to implement this feature in ASP.NET Core. 

If you are used to manipulate HTML forms, you probably know that each checkbox is a separate variable (or maybe an ngModel with AngularJS).  Demo

Sometimes, it could be usefull to manipulate all these checkboxes as a unique array.

angular.checkboxes module lets you turn your list of checkboxes into a unique destination array, providing :

• two-way binding: manipulate the destination array will check/uncheck the checkboxes AND check/uncheck the checkboxes will modify the destination array.
• no isolated scope for each checkbox: the directive does not create new child scope.
• a mtCheckboxController: internal controller can be injected to other directives. 

VSCode for the C# Developer - Tim Corey - NDC London 2023

VSCode is a nimble editor that can do just about anything. In this session, we will set up and configure VSCode for use in C# development. Then we will use it to build, debug, and deploy a small .NET Core web application to Azure.
Along the way, we will go over a list of the top C#-focused plugins for VSCode. Whether you are just getting started with VSCode or you are used to VSCode but want to start building C# projects, this session will get you up to speed fast. 

Add a new optimizer mode. Use --build-optimizer with ng build or ng serve to try it out.
We suggest to use it only in production builds. 

This is the first of a set of regular updates – we are targeting a new release each month.  In this first one we have over 300 improvements and bug-fixes and to help you get an overview we have added a new Updates section to our website.

Let’s take a look at what’s in store for TypeScript 4.2!

• Smarter Type Alias Preservation
• Leading/Middle Rest Elements in Tuple Types
• Stricter Checks For The in Operator
• --noPropertyAccessFromIndexSignature
• abstract Construct Signatures
• The --explainFiles Flag
• Improved Uncalled Function Checks in Logical Expressions
• Destructured Variables Can Be Explicitly Marked as Unused
• Relaxed Rules Between Optional Properties and String Index Signatures
• Declare Missing Helper Function
• Breaking Changes  

This release contains a fine selection of 70 hand-picked bug fixes across ReSharper, ReSharper C++ and dotCover. 

In this section, I’m going to cover how you can use SignalR outside of a Hub. In most asp.net core applications, you will likely want to communicate with the connect clients from within your application but outside of a Hub. You can accomplish this by using the HubContext.

For example, an ASP.NET Core MVC Controller or any other class that is instantiated by ASP.NET Core’s Dependency Injection.

The HubContext allows you to send messages to your connected clients. It has many of the same features to communicate with clients as when you are inside of a Hub.
