+# Build and Run .NET Applications With the CLI
+
+Sample code for the Code Maze article [dotnet build and dotnet run: Using the .NET CLI](https://code-maze.com/dotnet-using-the-cli-to-build-and-run-net-applications/).
+
+The folder holds the solution the article builds one command at a time:
+
+- `HelloWorld`: a console app that references the `Flurl` package and the `HelloWorldCore` library.
+- `HelloWorldCore`: a class library with one `Greeter` class.
+- `HelloWorldTests`: an NUnit test project that references `HelloWorldCore` and tests `Greeter`.
+- `HelloWorldSolution.sln`: the solution that groups the three projects.
+
+To build, run and test it:
+
+```
+dotnet build
+dotnet run --project HelloWorld
+dotnet test
+```
+
+## Why the solution file here is a .sln
+
+On the .NET 10 SDK, `dotnet new sln` creates an XML `.slnx` file, which is what the article shows. This
+folder stores a `.sln` instead, created with `dotnet new sln --format sln`, because the repository's CI
+looks for a `.sln` file in each sample folder. Both formats build the same three projects.
+
+The test project here replaces the template's placeholder test with a real test of `Greeter`, and its
+package versions are newer than the ones `dotnet new nunit` writes.
+
+## The walkthrough, as captured on 2026-10-11
+
+Every command below was run in order on Windows with .NET SDK 10.0.302 (runtime 10.0.10), so you can
+compare your own output with it. The working folder was renamed to `C:\Workspace\CodeMaze` to match the
+article. Two things are left out of the `dotnet add package` output: the three vulnerability-database
+lines, because their dated URLs change every day, and the end of the `Installed Flurl` line, which names
+the capture machine's NuGet package folder (on your machine it is the `.nuget\packages` folder in your
+user profile) and the package's content hash. The cut is marked with `...`.
