SQL Server 2019 preview builds on previous releases to grow SQL Server as a platform that gives you choices of development languages, data types, on-premises or cloud, and operating systems. This article summarizes what is new for SQL Server 2019. 

We have released new versions of JWT.io and the JWT Debugger extension, learn what's new. 

in this article, I will show how to take a medium-small demo app written using Visual Studio 2013, ASP.NET 4.5, VC 5, and Entity Framework 6 and turn it into a working ASP.NET 5 app employing Visual Studio 2015, MVC 6 and Entity Framework 7. And the new app will happily run on either the .NET 4.6 CLR or the .NET Core CLR. Let's get started.

Anatomy of the .NET dictionary

The internals of the .NET Dictionary class is a very common interview topic, so the information in this post might come in handy one day. Alternatively, use this new-found knowledge to impress friends and colleagues at every opportunity!

ASP.NET 2.0 introduced a concept of application offline. This mean that when there is App_Offline.htm file in the root of a web application directory then ASP.NET will shut-down the application, unload the application domain from the server, and stop processing any new incoming requests for that application. In ASP.NET 5, there is an open-issue for supporting this feature.
