Use ViewModels to manage data & organize code in ASP.NET MVC applications
The concept of the ViewModel isn't just for ASP.NET MVC, as you'll see references to ViewModels throughout the web in articles and blog posts about the MVC, MVP, and MVVM patterns. Those posts and articles can center around any number of technologies such as ASP.NET, Silverlight, WPF, or MVC... This post will investigate ViewModels as they apply to the world of ASP.NET MVC.

The desktop is here to stay. Sam Basu reviews how you can take advantage of the latest in .NET technologies and still build the apps your customers demand. 

Sam covers Windows Forms, XAML (UWP, WinUI), Progressive Web Apps, Electron, Blazor Mobile Bindings, .NET MAUI and building for Mac OS and Linux.  

Those of you who worked with ASP.NET web forms will recollect that certain server controls such as DropDownList have a property called AutoPostBack. This property when set to true automatically submits the form to the server whenever the selection changes and raises some server side event. In modern web development people prefer to use Ajax over AutoPostBack but at times AutoPostBack is what you might need. To that end this article shows how AutoPostBack can be implemented in ASP.NET Core applications. 

Performance of your ASP.NET web application is important. There is a lot of evidence to suggest that slow loading times and clunky interaction, will drive customers elsewhere. Even in the case of internal applications where the users have no option but to use the application, their satisfaction is tightly coupled to speed.

There are a ton of ways to improve the performance of a website, let's look at fifteen of them.
