Learn how to generate TwiML instructions to respond to texts and voice calls using XML Literals in Visual Basic .NET and ASP.NET Core Minimal APIs.

Learn how Twilio uses webhooks and TwiML to give you control over how to respond to a call or text message. You can generate TwiML in many ways, and with C# 11 you can now also use Raw String Literals.

Learn how to develop webhooks on your local machine using Visual Studio dev tunnels and ASP.NET Core.

Visual Basic .NET (VB) is not dead, but it's not getting the same amount of love as C# or even F#. Luckily, all that is .NET can be used by all .NET languages including VB, so you can still use ASP.NET Core and Minimal APIs with the VB language.

Learn how to create an SMS bot that looks up U.S. Congressional Districts and Representatives using the Google Civic Information API, C#, ASP.NET Core Minimal API, and Twilio SMS.

Learn how to get the public full URL of your ASP.NET Core application

Learn to integrate ngrok into ASP.NET Core's startup process to create secure public tunnels and automatically handle Twilio's webhooks with a single command

Learn how to access the ASP.NET Core's local server URLs in Program.cs, in controllers using Dependency Injection, and in IHostedService or BackgroundService.

Umbraco 9 has been built on top of .NET 5. As a result, you can now containerize your Umbraco 9 websites in Linux containers. Learn how to containerize Umbraco 9 with Docker.

Learn how to create the Azure infrastructure using the Azure CLI to host an Umbraco 9 website using Azure SQL and Azure App Service for Linux, and how to deploy your Umbraco 9 site.

.NET Core was a groundbreaking change to the .NET platform. It is blazing fast, open-source, and cross-platform across Windows, Linux, and macOS. With Umbraco 9, we finally get to enjoy all the new innovations from .NET Core. Read about my experience upgrading an Umbraco 8 website to Umbraco 9.

Earlier this week, the folks at the .NET Docs Show invited me over to talk about Twilio, .NET, and Blazor WebAssembly. We discussed different architectures, workflow diagrams, Twilio capabilities, and how to integrate them using ASP.NET WebAPI's and Blazor WebAssembly.

Captchas are often used as a way to combat spam on website forms. Unfortunately, this also makes it harder to verify the functionality of the forms using UI tests like Selenium. To work around this you can extend your website with a bypass form.

You can use smtp4dev during development to prevent emails from going out to real customers. This tool also supports IMAP which you can use to query emails for automated testing.

The ZipArchive wraps any stream to read, create, and update ZIP archives. You can send the result to the client using ASP.NET MVC, Razor Pages, and endpoints.

Using Microsoft's experimental Project Tye, you configured the proxy to forward requests to '/api' to the Web API, and all other requests to the Blazor WASM client.

Now that you can run .NET web applications without server-side code, you can deploy these applications to various static site hosts, such as Netlify.

Using Microsoft's new reverse proxy "YARP", you configured the proxy to forward requests to '/api' to the Web API, and all other requests to the Blazor WASM client.

Using Blazor WASM and the GZIP API's I created this little web application which you can use to compress and decompress multiple files using GZIP.

Using pre-rendering tools like react-snap, you can pre-render Blazor WASM. Additionally, you can integrate these pre-rendering tools inside of your continuous integration and continuous deployment pipelines.

The service-worker-assets.js file is generated during publish and any modification made to the listed files after publish will cause the integrity check to fail.

With ASP.NET Blazor WebAssembly you can create .NET applications that run completely inside of the browser. The output of a Blazor WASM project are all static files. You can deploy these applications to various static site hosts like Firebase Hosting.

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'.

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.

Blazor components render their template whenever state has changed and sometimes you need to invoke some code after rendering has completed. This blog post will show you how to run code after your Blazor component has rendered, on every render or as needed.

This article walks us through running a ASP.NET Core web application on Linux (RHEL) using systemd. The end goal is to serve ASP.NET Core directly via the built-in Kestrel webserver over port 80/443.
