In previous versions of Entity Framework, it is possible to return a subset of the columns of a table by projecting to a non-entity type. Up until version 2.1 there was no way to return non-entity types from queries in Entity Framework Core. This has been partially addressed now with the introduction of Query Types.

In this article, I look at the steps required to get TypeScript up and running in the context of a Razor Pages application. I discuss why you might want to do this, and I use Knockout for the purposes of demonstration. By the end of the article, I will have configured and used TypeScript to replicate part of the final code for the Single Page Application tutorial from learn.knockout.com.

In my last article, I looked at the experimental Blazor framework, using Cascading Dropdown Lists as an entry point. Since then, some feedback from Steve Sanderson to a question I asked has shown me a better way to implement this pattern.

UI generation and processing within web applications is moving increasingly to the client. Data processing and storage is still undertaken on the server, with JSON being the preferred format for exchanging data between the server and the client. There are a number of ways in which you can generate JSON when working with Razor Pages. This article explores some of them.

Most migrations that you execute when working with Entity Framework Core are likely to be straightforward - resulting in nothing more than an adjustment to the database schema. Sometimes, however, you might also want to include a task that requires longer than the default command timeout value (30 seconds in SQL Server) such as importing a lot of data.

I have just completed an article covering publishing a Razor Pages application to IIS on my Razor Pages dedicated site: learnrazorpages.com. While writing it (and publishing revised versions of the site) I uncovered a few stumbling blocks that might catch others out. So I thought they were worth highlighting here in their own post.

The Razor Pages PageModel class is part controller, part ViewModel. In this article, I take a look at the ViewModel part of the role that the PageModel plays, and how tools like AutoMapper can be used to reduce the amount of code you need to write when assigning values between your entity model and your ViewModel.

That's right - despite a number of questions, I am not writing a book on Razor Pages, the new page-based web development framework released as part of ASP.NET Core 2.0. But I have launched a web site for people who want to learn how to use ASP.NET Core Razor Pages.

The code for managing authentication in a Razor Pages application that is provided by the standard project template is a good starting point. However, chances are that you want to customise it to fit your own application needs. This article looks at the most common customisation requirements.

Razor Pages uses ASP.NET Identity as its default membership and authentication system. This article is the first in a series that explores the various parts of ASP.NET Identity as it relates to Razor Pages, and starts with an overview of the files generated as part of the project templates.

The Razor Pages framework is not the only thing to be introduced as part of .NET Core 2.0. A lot more of the existing full framework class libraries are also being ported across to .NET Core including System.Net.Mail. That means there is no longer any need to rely on third party libraries or services for email functionality in your .NET Core applications. So I thought I'd take the opportunity to illustrate sending email in a Razor Pages application.

One of the top level design considerations for the developers of a server-side web application framework is how to match URLs to resources on the server so that the correct one processes the request. The most straightforward approach is to map URLs to physical files on disk, and this is the approach that has been implemented by the ASP.NET team for the Razor Pages framework.

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.

Handler methods is a particularly nice feature introduced with the new ASP.NET Razor Pages framework . This feature enables you to determine what the user was doing when they requested the page, and to execute logic accordingly without having to resort to a bunch of conditional code.
