.NET Stage

Several new language features are coming to C# in the next release, included in Visual Studio 2019. Luca Bolognese will give us a quick look at how to avoid null reference exceptions with nullable reference types, how to consume and produce asynchronous streams, and much more.

Takeaways:

• Learn about all new features in C# 8.0 (nullable reference types, asynchronous streams, recursive patterns, switch expressions, ranges, default interface member implementations …)
• Learn about the history of the language
• Take a peek of possible future enhancements

Which NuGet package was that type in again? In this session, let’s build a “reverse package search” that helps finding the correct NuGet package based on a public type.

Together, we will create a highly-scalable serverless search engine using Azure Functions and Azure Search that performs 3 tasks: listening for new packages on NuGet.org (using a custom binding), indexing packages in a distributed way, and exposing an API that accepts queries and gives our clients the best result. Expect lots of live coding!

Takeaways:

• Understand the concept of triggers and bindings in Azure Functions.
• Understand when and how to create a custom binding.
• See these in action in a real-life example.

In this session we will show how to create a CI/CD pipeline with Azure DevOps to deploy your ASP.NET Core applications to Azure with WebApps and WebApps for Docker. We will show practices like building pipelines, Docker images build, publish to Azure and other docker Registries, handling secrets for your configuration files with Azure KeyVault and some tips and tricks to build and deploy your ASP.NET Core applications.

Takeaways:

1. Understand key concepts of Azure DevOps Pipelines
2. Understand the new YAML pipelines structure for deploy applications
3. Create a pipeline to build and deploy your .NET Core Applications to Azure

Azure Service Fabric is the underlying technology that powers core Azure infrastructure and PaaS services like Azure Cosmos DB, Azure SQL Database, Dynamics 365, and others. While having the opportunity to be able to run your microservices in a resilient and robust platform like Azure Service Fabric, it is not always a straightforward task, since you have to configure and manage the clusters yourself. For developers, this means understanding a lot of networking and hardware concepts. Enter Serverless: with this kind of architectures, you can build solutions that take advantage of cloud computing concepts, by reducing costs and increasing productivity without managing virtual machines, storage, or networking.

In this session, you will learn what is Azure Service Fabric Mesh: the Serverless flavor of Azure Service Fabric, why it is more important than ever to have this kind of platform and how can you adopt it in your projects.

Containers are one of the major breakthroughs in IT of the past few years and promise to revolutionize the way software is developed and deployed. Thanks to the support in Visual Studio 2019, time has never been more favorable to adopt them in our technological stack.

This talk will showcase a possible approach to port an existing ASP.NET Core solution to Docker, demonstrating how seamlessly Visual Studio integrates them in the development experience, while still embracing the advantages of dependency management that containers make possible.

After executing the solution locally on the development machine, we’ll explore which options we have in order to deploy it on Azure Kubernetes Service. We’ll show a possible example for a CI/CD pipeline in Azure DevOps and demonstrate how we can integrate it with the PaaS offering in Azure, such as Cosmos DB and Redis Cache.

3 important takeaways:

• What is Docker and why, as a developer, I should care about it
• How to port an existing, non-trivial ASP.NET Core solution to Docker
• How to run it in Azure with Azure Kubernetes Service

Port to .net core” they say. “It will be easy”, they say. When cool tech meets reality is when you get in trouble. In this session, we will share our learnings from porting a legacy medium-sized WebApi application to ASP.NET Core. We will talk about some of the techniques, major issues, common pitfalls and ways to avoid them on your journey to a modern app.

Key takeaways:

• Dependencies will eat you alive
• Best coding practices are a huge help
• Work in small incremental steps
• The mechanics of porting
• How ASP.NET/OWIN middleware maps to their ASP.NET Core counterparts
