What you'll learn

  • Get an overview about the current stage of the .NET platform with focus on .NET Core, ASP .NET Core, and C# 7 with their performance aspects
  • Get to know tools which are essential to measure the performance of a .NET Core application: Visual Studio Performance Tools, PerfView, BenchmarkDotNet, Perf and LTTng on Linux, Prefix, MiniProfiler
  • Performance characteristics of value types and reference types, the effect of async/await on performance, and performance of collections in the base library
  • Behind the scenes knowledge about C# 7: you will see what the compiler generates from C# 7 code and what performance implications this has on your application
  • New performance related APIs like Span<T>, ArrayPool<T>
  • Data access performance with Entity Framework Core
  • Ahead of time compilation for .NET Core with CrossGen, and removing dead code with the .NET IL Linker
  • Production monitoring for .NET Core and ASP .NET Core with Application Insights and Dynatrace

Course content

9 sections • 38 lectures • 6h 18m total length

  • Course Overview6:34
  • Note for .NET Core experts0:30
  • .NET Core History - Performance8:32
  • .NET Core Concepts and Definitions11:00

    Explore core .NET concepts and definitions, including .NET Standard 2.0, deployment options (self contained vs shared framework), and .NET Core 2.0 application types to boost cross-platform code sharing and performance.

Requirements

  • You should have some experience with the .NET framework
  • You already created at least 1 application either with .NET Core or with the .NET Classic framework
  • A little bit of .NET Core experience helps, but if you have solid a solid .NET Classic background, then it's also fine

Description

A few years ago, Microsoft decided to radically redefine the .NET platform. An open-source, cross-platform, high performance flavor of 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 knowledge from this course, you will be able to measure and optimize the performance of .NET Core (including ASP.NET Core), C# applications.

After a short wrap-up on .NET Core the course 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 using value types or choosing the right collection for the given problem. After that we will 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 like ArrayPool and Span and we will also look into the performance aspects of Entity Framework Core. We will talk about the ahead of time compilation story for .NET with CrossGen and IL trimming with the .NET IL Linker. We will finish the course by learning about production performance monitoring for .NET Core. 


Goal of the course 

  • Understanding why .NET Core and ASP.NET Core are great 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, Stackify Prefix, 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.NET Core applications: Span<T>, ArrayPool<T>, ASP.NET Core Precompiled Views, Entity Framework Core performance, .NET IL Linker, AOT compilation with CrossGen. 
  • Performance monitoring in production for .NET Core and ASP.NET Core: 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. 

 

Who this course is for:

  • If you are a .NET Core developer and you want to make sure your application does not break under production load then this course is for you!
  • Furthermore, if you are interested in performance and you like looking behind the scenes and understanding what really happens in your application then you will also find this course interesting.
