CS C#

C#: Running Code & Tools

.NET CLI

Modern C# uses the dotnet command-line tool. Install the .NET SDK first.

dotnet new console -n MyApp   # create a new console project
dotnet build                   # compile
dotnet run                     # build and run

Editors / IDEs

  • Visual Studio — the flagship Windows IDE (free Community edition). Full debugger, profiler, designer.
  • VS Code — install the C# Dev Kit extension for language support and debugging.
  • JetBrains Rider — cross-platform .NET IDE (paid, excellent for Unity work)

Key .NET CLI commands

dotnet new sln -n MySolution           # create a solution
dotnet new classlib -n MyLib            # class library
dotnet add package Newtonsoft.Json      # add a NuGet package
dotnet test                             # run tests
dotnet publish -c Release -o ./publish  # publish for deployment

NuGet (package manager)

NuGet is the .NET package ecosystem. Packages are hosted on nuget.org.

dotnet add package Microsoft.EntityFrameworkCore
dotnet list package                    # list installed packages

Unity development

C# is the scripting language for Unity, the game engine. Unity uses a modified version of Mono (or IL2CPP). Key differences: - Unity uses .NET Standard 2.1 API surface - Scripts extend MonoBehaviour for lifecycle events (Start, Update) - Use UnityEngine namespace for engine access
