A new type is introduced in .NET 5 called IJSObjectReference. This type holds a reference to a JavaScript object and can be used to invoke functions available on that JavaScript object.

Using IAntiforgeryAdditionalDataProvider you can harden ASP.NET Core's anti-forgery token feature by adding additional data and validating the additional data.

Using Twilio Voice you can add the ability to make and receive phone calls from your own ASP.NET web applications. Twilio’s helper library for JavaScript makes it easy to integrate client functionality into web front ends built with Blazor WebAssembly, and the Twilio NuGet packages provide you with convenient interfaces to Twilio’s APIs for server-side tasks.

The success of Blazor relies heavily upon how well it can integrate with the existing rich JavaScript ecosystem. The way Blazor allows you to integrate, is by enabling you to call JavaScript functions from Blazor and .NET functions from JavaScript also referred to as 'JavaScript interoperability'.

Microsoft's CORS library works, but the attributes force you to hardcode the CORS headers. By creating custom CORS attributes, you can read the CORS configuration from AppSettings or a custom config section.

Blazor Server is built on SignalR, which is built on websockets. Among things, websockets enable Blazor Server to push changes from the server to the browser at any time. You can build real-time UI's when you combine this with a real-time database.

Blazor Server is built on SignalR, and SignalR is built on websockets among other techniques. The combination of these technologies allow Blazor Server to push UI changes into the client without the client requesting those changes.

The robots.txt file’s main purpose is to tell robots (Google Bot, Bing Bot, etc.) what to index for their search engine, and also what not to. Usually you want most of your website crawled by Google, such as blog posts, product pages, etc., but most websites will have some pages/sections that shouldn’t be indexed or listed in search engines.

Application Performance Monitors provide you with a lot of data, but some of that data may not be relevant. Specifically, in Umbraco there is a page at \umbraco\ping.aspx that is being called frequently to keep the site alive. This is very useful to prevent the site from "dying" (?), but the data for this request isn't that relevant and could skew your statistics. Using Azure Application Insights ITelemetryProcessor, we can prevent ping request from being sent to Azure Application Insights.

Websites come in all shapes and sizes. Some are fast, some are beautiful, and some are a complete mess. Whether it's a high-quality site is irrelevant if people can’t find it, but search engines are here to help. Though the competition to get on first page is tough, this series will dive into some common practices to make your website crawlable.
