With Twilio Programmable Video you can add robust video chat functionality to web applications built with Angular and ASP.NET Core. With the Microsoft Azure App Service you can host your video-enabled apps on a fully managed, enterprise-grade cloud platform. Deployment and configuration are easy and take just minutes.

Build a Video Chat App with ASP.NET Core 3.0, Angular 8, and Twilio showed you how to integrate the Twilio JavaScript SDK and the Twilio .NET SDK seamlessly with ASP.NET Core and Angular. This post will show you how to deploy applications built with these technologies to the Azure App Service.

In this post you will learn how to publish your application to the Azure App Service, and securely configure the app on Azure to use the Twilio Video Chat API with the App Service settings. You’ll be able to try out the production applications’ video chat features and verify that it’s …

In a previous post you learned how to take a fresh application and deploy it to a Kubernetes cluster. While it’s great to start with a new application, most of us don’t get that luxury. Usually, you’re going to start off with something older and have to refactor and then migrate it.

This tutorial will show you how to take an existing application, refactor it using cloud-native principles, and deploy it to Azure Kubernetes Services. By the time you’re done, you will know how to move your own applications to the cloud.

Cloud Migration Patterns

When migrating applications to the cloud, there are a handful of different patterns you can follow. Which pattern you choose will depend on what you are trying to migrate and how much time you want to spend migrating them. Each of these patterns has different tradeoffs, so it’s good to understand them all when looking …

Realtime user interaction is a great way to enhance the communication and collaboration capabilities of a web application. Video chat is an obvious choice for sales, customer support, and education sites, but is it practical to implement? If you’re developing with Angular on the frontend and ASP.NET Core for your server, Twilio Programmable Video enables you to efficiently add robust video chat to your application.

This post will show you how to create a running video chat application using the Twilio JavaScript SDK in your Angular single page application (SPA) and the Twilio SDK for C# and .NET in your ASP.NET Core server code. You’ll build the interactions required to create and join video chat rooms, and to publish and subscribe to participant audio and video tracks.

This post provides instructions and code for creating a video chat app with ASP.NET Core 3.0. To learn how to build the …

As a .NET developer, I've been excited to explore all of the great things that came with the release of .NET Core 3.0. I have spent time playing with one of the newly launched technologies, Blazor, which allows me to build web applications targeting web assembly using HTML, CSS and C#. 

In my excitement, I went to see what the fuss was about. Following the instructions on Blazor.net, I updated Visual Studio 2019, installed the Blazor project templates, created a new Blazor app project, and then realized there were some choices I needed to make in order to build my shiny Blazor web application. As I made some choices and got going with my project I continued to see more and more places where I wished some things had already existed to help make development easier. 

As a result, I've put together this list of tips to help sort …

It's an exciting time to be a .NET developer as .NET Core 3.0 has reached general availability. With this release comes Blazor, Microsoft's take on building web applications using WebAssembly and the technologies you already know and love such as HTML, CSS, and C#. I published a prior blog post when Blazor was still in active development. It's time to join the release party and share our excitement about Blazor with Twilio and C#.

The first thing you should do when a new product gets announced is tell your friends, right - but what if we phoned them with a special note sharing our excitement? Let's build a web application that does exactly that - it uses Twilio to phone a friend, and is powered by Blazor.

Installing Our Developer Tools

Now in order to follow along - you'll need a few things first. You'll want to grab …

We all have good days and bad days. On a good day, we may be filled with positive thoughts and on a bad day, we may forget that anything was ever positive!

In this post, we will use Twilio to text your positive thoughts and affirmations to an Azure Function and save them in Azure Table Storage. We will then create a timer-based function that will send a random happy thought from the table storage via SMS to your friends.

This post assumes some basic knowledge of C# and RESTful APIs.

To get started, we will need:

• This GitHub project cloned
• A Twilio account and an SMS enabled Twilio number
• An Azure Account (sign up for free here)
• The latest .NET Core 2.2 SDK (download here)
• Azure Functions Core Tools version 2.6.666 or later
• Azure CLI version 2.0 or later
• Postman for testing our functions locally
• An IDE …

Using Polly, the resilience framework for .NET, you can gracefully handle lost packets, thrown exceptions, and failed requests which inevitably make their way into service-to-service communications on the web. Polly provides resilience strategies for your apps through policies such as Retry, WaitAndRetry, and CircuitBreaker, enabling you to implement fault tolerance in your distributed systems in a fluent fashion.

This post will introduce you to the Fallback policy and demonstrate its use in a straightforward ASP.NET Core 2.1 example. It will guide you in using the Fallback policy to handle failures you cannot recover from: when all else fails, fallback to this last line of defense.

If you’re not already familiar with Polly, the first post in this series on the Twilio blog introduced Polly, the .NET resilience framework. The second post build on the first and introduced the HttpClientFactory.

As the Labor Day weekend dwindles in the rear-view mirror we’re forced to confront reality: we’ll have to bid farewell to the felicities of summer and gear up for a new school year. It’s a bittersweet ritual of the season.

For .NET web developers there’s a significant new entry in the course catalog: Microsoft is moving ASP.NET Core 3.0 to general availability. The big announcement is set for September 23rd at .NET Conf 2019.

Haven’t bought your tickets yet?

No problem! .NET Conf is virtual this year, so everyone will be attending in the same class of service: no terrorizing cab rides, no standing in long lines, and no taking off your shoes unless you want to get comfortable.

If you feel the need to share the experience with your fellow techies in meatspace there are local events scheduled around the world. For UK developers, Twilio’s own Layla Porter …

As developers, we mostly focus on building applications. However, building the app is only half the story. To consider things “done,” we need to get that app deployed into the wild where people can use it. In the .NET world, there’s no shortage of ways we can host our apps, but today, I’d like to focus on building cloud native .NET applications.

In this post, you’ll learn about building cloud native applications in ASP.NET Core. You’ll learn how to design for the cloud, spin up an Azure Kubernetes Service instance, and deploy your application into the cloud. By the end of this post, you’ll have the tools to build and deploy your own cloud native ASP.NET applications.

What do you mean by “cloud native”?

“Cloud native” is one of those terms that sounds obvious, but there’s a more specific definition.

The Cloud Native Computing Foundation defines the term as follows: …

If you use data in a project then you have most likely had to map one model to another.  Whether you've done that in the constructor, a dedicated method, or used a mapper of some sort, it can be repetitive and tedious.

AutoMapper, a library for .NET written by Jimmy Bogard, has been around for a while.  It had a revamp to work with .NET Core and Dependency Injection but can still feel a little bit like magic.

I use AutoMapper for an internal Twilio tool.  I struggled to create valid maps that work without requiring me to map everything manually.

I found the best way to configure AutoMapper is by writing tests and lettingAutoMapper tell me exactly what I need to configure. Let me show you how that works.

I have created a solution in this repository that has the AutoMapper NuGet package already installed and all …
