When a documentation example imports a namespace not present in the fixed generated header—for example, using System.Diagnostics; followed by Stopwatch—this replacement deletes the import before compilation and then reports the otherwise valid standalone snippet as broken. Hoist each snippet's imports outside the generated class, or retain them in a scope where C# permits them, rather than discarding them.

The current documentation's project paths occur in dotnet test commands in README.md, while this parser only records paths from dotnet run --project. Consequently $projectCommands is empty for all current shell samples, so renaming or removing either documented test project would leave the new path-validation gate green. Extend extraction to the documented dotnet test form, including its positional project argument.

Greptile SummaryThis PR adds a CI documentation-compilation gate that extracts public C# snippets, compiles them against freshly packed Respire packages, and separately validates package IDs and project paths.
Confidence Score: 5/5The PR appears safe to merge. No blocking failure remains; the previously reported literal-ellipsis rejection was removed, while actual ellipsis placeholders remain subject to C# compilation.

When a Markdown or MDX example uses Docusaurus fence metadata, such as ```csharp title="Example.cs" or showLineNumbers, this exact-match condition silently skips the entire snippet. Those are valid documentation fences, so new public examples can bypass the compilation gate while CI still reports success; parse the language token separately from optional fence metadata.

The current installation samples in website/docs/getting-started.md and website/docs/integrations/dependency-injection.md use dotnet add reference, but this extractor recognizes only dotnet add package; the later project-path branches cover only run and test. Consequently, a renamed or misspelled referenced .csproj remains invisible to the new documentation gate. Extract reference arguments as project paths as well, accounting for the documented path/to/Respire/ placeholder prefix.

When documentation uses a valid four-or-more-backtick fence (for example, to show triple backticks inside a C# sample) or a fence indented by up to three spaces, this exact ^```csharp match skips the snippet entirely while CI still succeeds. Parse the opening fence's indentation and delimiter length, then require a compatible closing delimiter, so all Markdown C# fences are covered by the compilation gate.

When a non-target fence contains literal documentation examples—such as a four-backtick markdown block demonstrating a triple-backtick csharp fence—the outer fence is recognized here but never consumed because neither later language branch matches. The inner fence is consequently treated as a real snippet and can make CI compile or validate example text that is not an actual public code block. Advance to the compatible closing fence for every recognized opening delimiter, even when its language is not being tested.

Ports the documentation compilation gate from thomhurst/Kevlar#69.\n\nExtracts C# fences from README and Docusaurus documentation, compiles 87 complete snippets against freshly packed Respire packages, and requires explicit reasons for two contextual exclusions.
