Course details
A few years ago, Microsoft decided to radically redefine the .NET platform. An open-source, cross-platform, high performanceflavorof the .NET framework was created: this is .NET Core. Additionally, C#, the most widely used .NET programming language also evolved over the years. These new developments include many performance improvements.
The goal of the course is to give you deep understanding about these performance improvements. By applying the knowledgefromthis course, you will be able to measure and optimize the performance of .NET Core (including ASP.NETCore), C#applications.
After a short wrap-up on .NET Corethecourse introduces you to the first pillar of the performance topic: measuring performance. You will learn to use tools that you can apply to measure the performance of your code running on .NET Core.Then we will focus on some important performance tricks like reducing the pressure on the GC by usingvaluetypes or choosing the right collection for the given problem.After that wewill see what the compiler does behind the scenes when it compiles your C# 7 code and what performance implications this has.We will talk about some new performance related APIs likeArrayPooland Span andwe willalsolook into the performance aspects of Entity Framework Core. We will talk about the ahead of time compilation story for .NET withCrossGenand IL trimming with the .NET IL Linker. We will finish the course by learning about productionperformancemonitoringfor .NET Core.
Goal of the course
- Understanding why .NET Core and ASP.NETCorearegreat platforms to create high performance applications
- Learning about tools that can measure the performance of your .NET Core code:Visual Studio Performance Tools, BenchmarkDotNet, MiniProfiler, StackifyPrefix, LTTng and Perf on Linux, ETW and PerfView
- Understand the latest language features of C# and how they affect performance
- Advanced tools to improve the performance of your .NET Core and ASP.NETCore applications:Span<T>, ArrayPool<T>, ASP.NETCore Precompiled Views, Entity Framework Core performance, .NETILLinker, AOTcompilation with CrossGen.
- Performance monitoring in production for .NET Core and ASP.NETCore: Application Insights and Dynatrace
Course style
The course is a mix of theory and practice. Tools and concepts with their theoretical background will be introduced with slides and then the theoretical knowledge will be applied in demos.
