Sessions in ASP.NET Core 1.0

07 April 2015 13:39

ASP.NET MVC ASP.NET 5 ASP.NET Core

ASP.NET Core 1.0 is being designed so that your application is only dependent on features that it actually needs. This is achieved in large part by creating a composable framework, where the developer opts in to non-essential features - a number of which are baked in to traditional versions of ASP.NET. One of the features that this applies to is Session State. This article looks at how to obtain and use session state in ASP.NET Core 1.0 applications. It has been updated to reflect Release Candidate (RC) 1 of ASP.NET Core 1.0

Error Handling in ASP.NET Razor Web Pages

10 March 2015 13:07

ASP.NET Web Pages WebMatrix

Bang! An unhandled exception occurred during the execution of the current web request. And that's it - your visitor is met with the yellow screen of death and they are left wondering what they did wrong. You might not even be aware of what's just happened - unless your visitor can find some way of alerting you, oh, and they bother to do so. That's the problem with run time errors; the code worked fine when you ran it on your machine. But then along came a user and they tried to do something you didn't anticipate and broke your site. So what should you do about this?
