Optimizing for the Cloud – Lightning-speed .NET Container Apps

In this session, we will explore how to optimize .NET applications for the cloud by reducing cold start time and performance for containers in Microsoft Azure. Cold start time can be a critical factor for serverless applications, impacting both performance and cost. With the latest features in .NET, such as Profile Guided Optimization (PGO), Native AOT, Trimming and Crossgen2, you can significantly reduce cold start time for your containers, improve serverless performance and thus save money. We will discuss practical ways to utilize these technologies and share best practices for optimizing .NET apps in Microsoft Azure.

Getting started with Kubernetes for your .NET Application

Kubernetes is the new hotness for deploying your applications, promising to give a consistent way to define and deploy your application structure across various cloud vendors as well as on-premise infrastructures.
This session will make you familiar with the basic features of Kubernetes, show how to deploy a containerized ASP.NET Core application to an Azure Kubernetes Service (AKS) cluster using Helm.

Exploring Source Generators

Meta-programming is now easily available to all of us in C#! Roslyn’s “Source Generator” feature is a handy tool for making day-to-day work quicker and automating tedious coding tasks or build processes with direct compiler integration.
While this compiler feature was introduced in C# 9 already, new features in .NET 6 now make use of it to help you with tasks like JSON serialization and logging.
In this session, we will look into what source generates can or could be used for, explore the new source generator based .NET 6 features and implement a custom source generator.

MSBuild: Understand and customize your .NET build

MSBuild is the powerful build system used in .NET. With .NET Core, it is now widely used cross-platform and has been open sourced.
Since MSBuild has been powering .NET Core builds since 2017, it has unlocked remarkable possibilities that were not possible with project.json.
It has a programming language of its own. This session introduces to this programming language, explains common build customization techniques, helps avoid pitfalls when setting up your custom build logic and explores strategies to investigate build errors.

Writing Fast Code Using .NET Core 3.0 Hardware Intrinsics

.NET Core 3.0 now gives you access to the raw power of modern CPUs and allows you to supercharge compute-intensive code that you couldn’t really optimize any further without using intrinsic functions provided by C/C++ compilers or even writing CPU-specific Assembler code.
This session explains how code can be vectorized and optimized for modern processors using new vector types and special classes providing access to AVX, SSE and more CPU instruction sets and shows you how to progressively take advantage of these processor features when available on target machines.

Securing your Application with OpenID Connect

When developing for modern service landscapes we need to deal with terms like OAuth, OpenID Connect, JWT, Bearer Tokens and more. In this vast landscape auth possibilities for authentication, it is easy to get lost. This session helps to understand and use the principles that underly modern authentication flows.
