XE dotNETConf HotTopics - C# 9 - Session 13-11-2020

This repo contains some slides and all the DEMO for my XE online session about dotNETConf 2020 HotTopics where I talk about C# 9

Initial setup project

I used latest official release of .NET 5 and create a simple Console App for easy startup:

dotnet new console -n csharp9 -o csharp9
cd csharp9
dotnet run

I also edited the default csharp9.csproj file to specify the C# Languauge 9

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net5.0</TargetFramework>
    <LangVersion>9.0</LangVersion>
    <Nullable>enable</Nullable>
 </PropertyGroup>

</Project>

Try it

To try my project sample simply open VSCode and install C# Extension when promted

Than in the integrated Terminal simply run dotnet watch run to execute the code, and follow istruction in the comment to run/test all my sample one-by-one to learn the new C# 9 features:

• Top Level Program + basic Class
• Init Only Properties
• Manual Immutable class
• Record + with-expression
• Positional Record + destructuring and inheritance
• Target Type new-Expression
• Enhanced Pattern Match
