.NET 7
Working with Sass in an ASP.NET Core application
calendar_today 20 April 2023 12:40
Sass (Syntactically Awesome Style Sheets) is a is a scripting language that is used to generate cascading style sheets (CSS files). Its syntax is very similar to CSS itself, but it supports the use of variables, nesting, mixins and selector inheritance, none of which are available in CSS itself. However, these features help you to organise and maintain your web application's styles. In this article, I look at the steps required to incorporate and configure Sass in your ASP.NET Core project in both Visual Studio, and VS Code.
Why doesn't my ASP.NET Core 7 web app launch on HTTPS?

Up until .NET 7, when you use the dotnet run command to run your ASP.NET Core Razor Pages (or MVC) app, the built-in Ketstrel web server would listen on two URLs, one with a
http protocol and another that uses the https protocol. This behaviour is documented in many places (including my book) so it might come as a surprise when
you run your new .NET 7 app from the command line and it is only available on an
http binding. Something changed in .NET 7. What is it and how do you test your .NET 7 web app under
https?
Executing async operations onchange in Blazor

Blazor's two-way databinding model is extremely powerful, but sometimes
it can get in the way of what you want to do. For example, you might
want to execute an asynchronous operation such as remote validation when a value changes in a
textbox. Perhaps you want to check instantaneously that the value - a username maybe -
doesn't already exist in a database before you accept a new
registration. You cannot add an onchange event handler if
you already have a value bound to the element, so what can you do? In this
article, I look at solutions for both HTML elements and EditForm input
validation components up to an including .NET 7, and a new
feature released in .NET 7.0.1.
