There are a number of ways that you can maximise code re-use within a Razor Web Pages site: Layout pages, helpers, functions and so on. As you build more sites, you soon find that you are repeating code between them. You might have a collection of custom utility functions and extension methods, for example that you find yourself copying and pasting across sites. Over time, this will become a maintenance nightmare as different versions of the methods live in different sites. This article shows how to solve that problem easily by creating a library that can be shared across multiple sites.

Entity Framework Code First Migrations enable changes to your model to be propagated to your database through code. Prior to the introduction of migrations, changes to the model resulted in the database being recreated from scratch with attendant loss of data. During development, this may not cause too many problems, but once the database has been deployed into production, it's another story. Migrations solve the problem in that changes are applied to the database schema without loss of data.

The default authentication mechanism built into ASP.NET Web Pages site templates is Forms Authentication via the SimpleMembershipProvider, which is designed to enable authentication of users against a database. This requires the user to know their user name and password, and to enter those whenever they want to log in to access restricted areas within a site. If you are using the ASP.NET Web Pages framework to build an Intranet site that will be hosted within your own corporate network (i.e. client machines and web server are in the same domain), you can use Integrated Windows Authentication instead which simplifies authentication dramatically.

SignalR is a library that simplifies the creation and management of persistent connections between web servers and clients. This facilitates the development of applications that can display updates to data held on the server in real-time. Chat applications are the most obvious beneficiaries of this technology, but line-of-business applications that need to report availability to users can benefit too. Here, I look at extending the canonical SignalR chat example to incorporate a "who's typing" feature, and I also extend my previous Knockout example to use SignalR.
