In the last ASP.NET Community Standup, Jon Galloway gave my introductory Razor Pages article a shout out (thank you, Jon). During the discussion that ensued, Scott Hanselman asked for the "elevator pitch" for Razor Pages. Well, here's mine.

Since ASP.NET 4.5, zipping and unzipping files can be done with classes from within the .NET framework. Despite that, nearly all examples that illustrate working with zip files in ASP.NET applications feature third party open source compression libraries. This short article attempts to correct that by demonstrating the use of the System.IO.Compression classes to unpack an uploaded zip file, and to create one for download in an ASP.NET MVC application.

If you have forms on your site that take a user's personal details, you should protect the page by running it under HTTPS. That way, any data that's posted from the form (email address, credit card number etc) is encrypted and hidden from prying eyes. It's not just e-commerce sites that should be protected. Intranets and other line of business apps that require authentication, blogs with comment forms that ask for email addresses and so on. The main barrier to this in the past has been the cost of the digital certificate (SSL Certificate) that asserts that you are who you say you are. LetsEncrypt is a free, automated, and open Certificate Authority that removes this barrier.

For the vast majority of ASP.NET Core MVC applications, the conventional method of locating and loading views from the file system does the job nicely. But you can also load views from other sources including a database. This is useful in scenarios where you want to give users the option to craft or modify Razor files but don't want to give them access to the file system. This article looks at the work required to create a component to obtain views from other sources, using the database as a working example.

Now that the RTM of ASP.NET Core has shipped, the ASP.NET team are looking at the features that were left behind including SignalR and Web Pages. The ASP.NET Core road map always had those items scheduled for inclusion in the first major release after RTM, which will be ASP.NET Core 1.1. Recently, the ASP.NET Team provided an update on GitHub on the goals driving the next version of Web Pages which provides an interesting insight into the potential features of the framework.

The search facility on this site has been rudimentary at best. I have recently upgraded it to take advantage of the Full-Text Search feature in SQL Server. Although it is still a basic implementation, it is a vast improvement on the search system that existed before, which was based on Entity Framework dynamically generating SQL LIKE clauses. This article describes how I got SQL Server Full-Text Search up and running.

I've seen a lot of questions about the best way to import data from uploaded Excel files to a SQL Server database in an ASP.NET application. Most solutions involve the use of the JET or ACE OLEDB providers to read data from the saved Excel file, and some even show how to use Office Interop to obtain the data. However, all of these solutions rely on additional components being installed on the server, and they also require the uploaded file to be saved somewhere, even temporarily, which creates an additional maintenance task. The solution that follows makes use of a Nuget package that gets deployed with your application and can work with streams, so the uploaded file doesn't need to be saved. It is, in my submission, THE best way to import data from uploaded Excel files to SQL Server in an ASP.NET application.
