Type: Documentation
Added `CliApplication`, `CliApplicationBuilder`, `CliCommandDispatcherService`, `CliCommandLineArguments`, and `ExitCode`, giving consumers the ASP.NET Core-style `CreateBuilder(args)` / `Build()` / `Run()` bootstrap the design docs describe. The builder wraps a `HostApplicationBuilder` and the application wraps the built `IHost`, both through composition rather than inheritance, since the concrete host types are `sealed`. The dispatcher is a hosted service that currently reports no command has been wired up yet, because the command model does not exist, and requests shutdown afterward so a CLI process exits instead of running forever like a web server. Pinned the .NET SDK version in a new `global.json` (`rollForward` disabled) and turned on `RestorePackagesWithLockFile` for `clinet-core` and `sample-app`, adding their `packages.lock.json` files. `clinet-core` now references `Microsoft.Extensions.Hosting`. Documented the new API in a new User Manual article, Building Applications, linked from the User Manual index. Updated the C# style, dependency-management, and file-naming docs, and `CLAUDE.md`, to match: XML documentation is now required on every member including `private` ones, `#region` blocks are always used with a fixed ordering, and `global.json` is called out as a pinned dependency. Added `dotnet.defaultSolution` to the shared VSCode settings so the C# extension finds the solution despite it living under `source/`, and added a few missing words to the CSpell dictionary. Also, added C# formatting to dprint. This work was done with the help of Claude Code. The design and architecture of the hosting layer was created with the help of Claude Code, and the documentation was largely written by Claude Code. Co-Authored-By: Claude <noreply@anthropic.com>
