Changes

BuilderPattern example

Layer / File(s) Summary
Example project and builder usage
v2/rscg_examples/IncrementalSourceGenerator.BuilderPattern/...
Adds project metadata, a .NET 10 sample, Person, annotated PersonBuilder, fluent builder usage, and generator metadata.
Generated behavior documentation
v2/rscg_examples_site/docs/RSCG-Examples/IncrementalSourceGenerator.BuilderPattern.md, v2/book/...
Documents usage, generated builder code, factory creation, domain rules, screenshots, and downloadable documentation.
Catalog and index publication
README.md, later.md, v2/RSCGExamplesData/..., v2/rscg_examples_site/docs/..., v2/rscg_examples_site/static/exports/RSCG.json
Adds the generator to repository and site catalogs and updates example counts to 283.
Guided tours and author page
v2/.tours/..., v2/rscg_examples/.../video.json, v2/rscg_examples_site/docs/Authors/...
Adds the CodeTour, recorded-video steps, and author listing.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟠 High · up to b96d1

The new example currently has a compile-blocking class declaration mismatch, and its video automation cannot run because the script is invalid and points to the wrong tour location. Merge should be blocked until these issues are corrected; the remaining documentation, accessibility, and metadata fixes are minor.

Inline comments:
In `@v2/book/examples/IncrementalSourceGenerator.BuilderPattern.html`:
- Around line 23-58: Add concise, descriptive alt attributes to all six
screenshot img elements, identifying the project, source, or generated file
shown; use non-empty text because these images convey code content.

In `@v2/book/list.html`:
- Line 20: Update the heading text in the list content to escape the
greater-than character as an HTML entity, or replace it with a plain separator,
so it no longer triggers the spec-char-escape check.

In `@v2/rscg_examples_site/docs/Authors/Martin_Barrett_Nielsen.md`:
- Line 6: Remove the leading indentation from the author entry so Markdown
parses the link normally rather than treating it as a code block; preserve the
existing link, badges, and date content.

In
`@v2/rscg_examples_site/docs/RSCG-Examples/IncrementalSourceGenerator.BuilderPattern.md`:
- Around line 135-136: Remove the backslashes escaping braces in the fenced C#
property declarations for FirstName and LastName, leaving the braces as valid C#
syntax.

- Around line 1-3: Correct the duplicated “that” in the description: update
v2/rscg_examples/IncrementalSourceGenerator.BuilderPattern/nuget.txt lines 1-3
and
v2/rscg_examples_site/docs/RSCG-Examples/IncrementalSourceGenerator.BuilderPattern.md
lines 29-31 from “that that reduces” to “that reduces,” keeping both publication
artifacts consistent.

Apply the same fix in `@v2/docFind.json` at line 1698: README copy of the same
description.

In
`@v2/rscg_examples/IncrementalSourceGenerator.BuilderPattern/src/Builder/Person.cs`:
- Around line 10-15: Update the Person class declaration in the documentation
source snippet to include partial, matching the generated public partial class
Person declaration while leaving its properties and FullName method unchanged.
- Around line 12-13: Resolve the nullable contract for the FirstName and
LastName properties in Person so they cannot remain unintentionally null under
the enabled nullable context. Initialize both properties with valid defaults,
mark them nullable, or validate that required values are provided before Build()
returns a Person; keep the chosen behavior consistent with the With... methods
and Builder.Build flow.

In `@v2/rscg_examples/IncrementalSourceGenerator.BuilderPattern/video.json`:
- Around line 28-29: Update the video script’s tour step to reference the
workspace-root `.tours/` directory instead of `src/.tours/`, matching the new
tour location under `v2`; leave the preceding hide step unchanged.
- Around line 35-38: Update the video script JSON near the final browser and
waitseconds steps: remove the invalid SpeakTest entry unless it is required, in
which case make it a valid quoted property, and remove the trailing comma before
the closing array bracket so the script parses successfully.

Remove the indentation from the author entry.

The eight leading spaces can make Markdown render the line as a code block instead of parsing the link. Use an ordered-list marker or remove the leading spaces.

The generator emits public partial class Person, but Person.cs declares public class Person. This mismatch causes CS0260 and prevents compilation.

Update the corresponding source snippet in the documentation.

🌐 Web query:

IncrementalSourceGenerator.BuilderPattern 1.0.2 generated builder WithFirstName Build nullable

💡 Result:

The package IncrementalSourceGenerator.BuilderPattern (version 1.0.2) is a NuGet package designed to facilitate the implementation of the Builder design pattern in.NET using Roslyn incremental source generators [1]. Regarding your query about "WithFirstName" and "Build" support, particularly for nullable types: 1. Method Naming Convention: Generators of this type typically analyze public properties of a target class (marked with an attribute like [GenerateBuilder]) and automatically generate fluent "With" methods corresponding to those property names [2][3]. If your class has a property named FirstName, the generator will produce a WithFirstName method as part of the builder's fluent API [2][3]. 2. Build Method: These generators provide a Build method to finalize the object construction [2][3]. Depending on the specific implementation, the Build method returns the target object type [2][3]. 3. Nullable Support: Support for nullability depends on the specific source generator implementation you are using. Generally, modern.NET source generators respect C# nullable reference types. If a property is defined as nullable in your source class (e.g., string?), the generated builder typically reflects this in the generated With method signature [4]. Because there are multiple different NuGet packages providing "Builder Pattern" source generation—such as BuilderPatternGenerator, FluentBuilder, and others [5][6][7]—the exact behavior for nullable parameters or strict compile-time validation can vary. You should verify your project's specific dependency and refer to its generated output (found in the "Dependencies > Analyzers" node in Visual Studio) to see the exact signatures created for your properties.

github MartinBarrettNielsen11 Incremental-source-generator-builder-pattern README generated code Build WithFirstName

💡 Result:

Based on the available information, there is no widely recognized repository matching the exact name "Incremental-source-generator-builder-pattern" associated with the user "MartinBarrettNielsen11". It is likely that this repository is private, deleted, or was a personal/niche project [1][2][3][4]. However, the pattern of "Incremental source generator" combined with a "Builder pattern" and "WithFirstName" methods is a common implementation pattern in C# development [5][6]. Specifically, the library M31.FluentAPI features similar functionality and documentation examples using "WithFirstName" in its README [7][8]. If you are looking for code that uses the "Build WithFirstName" fluent syntax, it is typically generated via C# Incremental Source Generators by: 1. Marking a class with an attribute (e.g., [FluentApi] or [GenerateBuilder]) [7][8][6]. 2. Having the source generator scan for properties or members to create corresponding.With[PropertyName] methods [7][8][6]. 3. Providing a.Build method to return the final object [7][8][6]. If you have a specific link or more context, that would help in identifying the exact implementation you are referring to.

Resolve the nullable contract for Person properties.

Builder.csproj enables nullable reference types, but FirstName and LastName are not initialized. Build() leaves them null when their With... methods are not called. Initialize them, declare them nullable, or enforce required values during Build().

Fix the invalid JSON before publishing the video script.

SpeakTest=" " is not valid JSON, and the trailing comma before ] is also invalid. The parser fails before any video step runs. Remove SpeakTest unless the consumer requires a valid quoted property, and remove the final comma.
