Course notes from LinkedIn Learning.

What is .NET?

• A combination of languages (e.g. C#) and libraries (e.g. the .NET Framework or (Core) Runtime).

Installing .NET

• Download Visual Studio 2022 Community Edition for Windows (license terms), or download .NET Core and use VS Code.

What is a .NET Hello World app?

• The video mentions a “C# 101” series. That can be found on YouTube or Microsoft Learn.

.NET: Basic debugging

• Set breakpoints by clicking to the left of the line number in Visual Studio, and start debugging by clicking the green “Play” button in the toolbar.
• Breakpoints can be set to only trigger when certain conditions are met.
• The Debug target compiles executables for debugging, while the Release target creates optimized code for shipping to users.

.NET: Adding a class library

• Playback of this episode terminated prematurely for me. The video/series is available on YouTube.

.NET: Using a NuGet package

• NuGet is a package manager for .NET libraries. Packages can be browsed on the NuGet Gallery.
• Packages can be added as dependencies by right-clicking a project in Visual Studio and selecting “Manage NuGet packages”.

.NET: Unit testing

• The XUnit testing library uses [Fact] attributes to designate methods as unit tests.
• Other (unit) testing frameworks for .NET include:
  • NUnit.org
  • MSTest

.NET: Publishing an app

• Console applications can be published “self-contained” (with all dependencies), in which case the target OS does not need .NET (Core) to be installed beforehand.
