The previews of EF Core 5.0 require .NET Standard 2.1. This means:

• EF Core 5.0 runs on .NET Core 3.1; it does not require .NET 5.
  • This may change in future previews depending on how the plan for .NET 5 evolves.
• EF Core 5.0 runs on other platforms that support .NET Standard 2.1.
• EF Core 5.0 will not run on .NET Standard 2.0 platforms, including .NET Framework. 

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. 

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. 

Last week, at ng-conf, the Angular team at Google provided the web developer world with an update on the state of Angular 2.

Jonathan then demoed a preview of the upcoming TypeScript 1.5 release via an Angular 2 sample application.
