Sharp C# hops, F# sings a tune,
VB joins by afternoon.
Npgsql threads the stitch so neat,
CrateDB docs make connections sweet.

Pre-merge checks and finishing touches

❌ Failed checks (1 inconclusive)

Check name	Status	Explanation	Resolution
Description Check	❓ Inconclusive	The pull request description contains a vague phrase ("What the title says") followed by preview links to three newly added documentation pages for C#, F#, and Visual Basic. While the preview links provide concrete evidence of what was added and are related to the changeset, the descriptive text itself uses non-descriptive language that conveys minimal meaningful information about the content or purpose of the changes. The description is clearly related to the changeset (adding .NET driver documentation), but the extremely vague text portion creates ambiguity about whether it meets the threshold for a clear description.

✅ Passed checks (2 passed)

Check name	Status	Explanation
Docstring Coverage	✅ Passed	No functions found in the changes. Docstring coverage check skipped.
Title Check	✅ Passed	The pull request title "Driver: Add pages about C#, F#, Visual Basic" accurately reflects the main changes in the changeset. The PR adds three new documentation pages (csharp.md, fsharp.md, and visualbasic.md) under the drivers section, along with corresponding updates to the index and links documentation. The title is concise, specific, and uses clear language that would allow a reviewer scanning commit history to immediately understand the primary purpose of this PR without requiring additional context.
