To get started developing applications with C# 10 and .NET 6, the .NET 6 SDK needs to be installed; this also installs the .NET 6 runtime.
To confirm the installation, open a command window and use the .NET command-line interface dotnet.exe. The --version option displays the highest version of the SDK installed on your machine, or the version specified in a global.json location at or above your current directory (dotnet --version).
Use dotnet --list-runtimes to show all of the .NET Core Runtimes installed on your machine. There is Microsoft.AspNetCore.App for building ASP.NET Core applications, Microsoft.NETCore.App which is the foundational runtime for .NET, and Microsoft.WindowsDesktop.App for building WinForms and WPF applications.
Use dotnet --list-sdks to show all of the SDKs installed.
New with .NET 6 is a command to check the installed versions and runtimes for updates (dotnet sdk check).
To pin your project to using an earlier version of the .NET SDK, you can use a global.json file.
For this book, you will want to install Visual Studio 2022 Community with the .NET desktop development, ASP.NET and web development, and Data storage and processing workloads. You should also select Class Designer and Git for Windows under "Code tools" on the "Individual components" tab before you click Install.
Visual Studio 2022 is a complete IDE for software development using .NET and C#. You can easily create a new console app through the "Create a new project" option and choosing the Console app template. Visual Studio also gives you the ability to design classes and other types (such as interfaces or delegates) in a visual manner.
{{c1::Visual Studio Code}} is a popular IDE by Microsoft (in addition to Visual Studio 2022) that is fast with limited functionality that can be customized through extensions.
To restore and build all the projects in your solution: dotnet build
To run your project without debugging: dotnet run
