C# is the language, but .NET is the platform that builds and runs it. Before going deeper into code, it helps to know what is actually happening when you press run: how your source is compiled, what executes it, and which tools sit around it. This module gives you that picture.
You'll start with what .NET is and what you can build with it, then learn the difference between the SDK, the runtime, and the CLR. From there you'll work with the dotnet CLI to create, build, run, and publish projects, and use NuGet to add third-party libraries to your code.
With the platform and tooling in place, you'll be ready for the next module, Advanced C#, which goes beyond the basics of the language.
A quick tour of what .NET is, a bit of its history, how the ecosystem fits together, and the kinds of software you can build with it.
Clears up three terms that beginners often mix up: what the SDK contains, what the runtime does, and where the CLR fits when your code runs.
Walks through the commands you will use every day with the dotnet CLI: build, run, watch, clean, and publish.
Shows how to add a NuGet package to a project from the command line and use it in your code, from creating the project to running the app.
