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.

Current users of ASP.NET Web Pages have been eagerly awaiting news on what ASP.NET Core holds for them (if my inbox is anything to go by). The roadmap suggested that a new version of Web Pages would be forthcoming after the initial release of .NET Core, but that item was subsequently removed. Instead, a new cross platform page-centric web development model called Razor Pages has been made available in preview form. Here, I show you how to get started with it and explore its similarities with Web Pages. In future articles, I will take a closer look at the wide range of differences.

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.

Redesigning a framework from the ground up provides an opportunity to implement an improved API. The team working on Entity Framework Core have certainly grabbed that opportunity in respect of the DbContext class, which sees a bunch of new data manipulation methods not available in Entity Framework 6 or earlier.

Entity Framework Core is the new lightweight version of Entity Framework designed to work with .NET Core applications. Just like ASP.NET Core, it has been rewritten from the ground up, and includes some new ways of doing things. One of those is the introduction of the TrackGraph method for handling complex data in disconnected scenarios such as MVC or Web API applications.

Web Developers who use Microsoft technologies have always relied on the Server.MapPath method to resolve file paths in classic ASP and ASP.NET Web Forms and MVC versions up to and including 5. This method has not been included in ASP.NET Core, so what do you use instead?
