Generator startup restoration

Layer / File(s) Summary
Startup restore sequence
v2/start.bat
Restores Generator dependencies before launching services and adds --no-restore to the LocalAPI watch command.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to da0e8

The PR adds a new logging example and publishes related documentation, tours, and video metadata, but the current content includes invalid JSON that prevents the video definition from loading and several incorrect walkthrough or documentation references. Merge should wait until these published assets and the startup command are corrected.

🟡 Changes recommended

The new demo code exposes a *Core method publicly (confusing/incorrect public surface for the generator pattern) and has minor formatting inconsistencies that should be corrected.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

Adds a new Roslyn Source Generator example for AOP.Logging.SourceGenerator to the v2 examples set, and updates the site/book/export indexes so the repository reflects 289 total examples.

Changes:

  • Introduces the new AOP.Logging.SourceGenerator example project (code, metadata, docs, tour, video script).
  • Updates aggregated data sources/exports (CSV/JSON) and documentation pages to include the new example and adjust counts.
  • Tweaks v2/start.bat to restore once up-front and run the Generator watcher without restoring each time.

minimal, and validate.

Inline comments:
In `@v2/.tours/AOP.Logging.SourceGenerator.tour`:
- Around line 27-29: Update the tour setup so DemoLog.csproj is built before the
step that opens Person_Logging.g.cs. Enable or add the required build command
before showproj and retain the existing generated-file navigation afterward.
- Line 16: Update the CodeTour steps using the pattern “this is the code” so
they reference stable text that exists in the corresponding source files, or
remove the pattern when no reliable match is available; ensure both affected
steps can still identify their intended targets.

In `@v2/book/examples/AOP.Logging.SourceGenerator.html`:
- Line 2: Add the HTML5 doctype declaration before the h1 heading in the
generated document, preserving the existing heading and content unchanged.

In `@v2/book/list.html`:
- Line 20: Update the heading text in the list markup so the greater-than
character is encoded as > within the existing “=>” text, preserving
the browser-rendered output.

In `@v2/rscg_examples_site/docs/indexRSCG.md`:
- Line 23: Remove the trailing space from the AOP.Logging.SourceGenerator link
text in the index entry, changing the link label to end immediately before the
closing bracket so it satisfies markdownlint MD039.

In `@v2/rscg_examples_site/docs/RSCG-Examples/AOP.Logging.SourceGenerator.md`:
- Line 61: Update the headings in the RSCG-Examples documentation so they use
valid, sequential Markdown levels: change the Features heading from level 6 to
level 3 and correct the heading at the later referenced section, along with
subsequent deeper headings, to remain within levels 4 through 6. Preserve the
existing section hierarchy and ensure no heading uses more than six #
characters.
- Line 228: Remove the unnecessary backslashes before opening and closing braces
throughout the fenced C# examples in the AOP.Logging.SourceGenerator
documentation, including the object initializer near var user and all other
escaped-brace occurrences, so copied snippets contain valid C# syntax.

In `@v2/rscg_examples/AOP.Logging.SourceGenerator/readme.txt`:
- Around line 39-64: Update the README quick-start to match the checked-in
DemoLog sample: use the project’s actual Core, SourceGenerator, and Console
setup, describe manual DefaultMethodLogger creation and SetMethodLogger usage,
and change the sample path reference from ./samples/AOP.Logging.Sample to
./src/DemoLog. If retaining the AddAopLogging and AddTransientWithLogging
example, clearly label it as upstream API documentation rather than the
checked-in sample.

In `@v2/rscg_examples/AOP.Logging.SourceGenerator/video.json`:
- Around line 36-38: Correct the JSON syntax in the video definition by changing
the SpeakTest property assignment to use a colon and removing the trailing comma
after the final waitseconds array element, ensuring the document parses as valid
JSON.
- Line 29: Update the arg used by StartTourVSCode.Execute in video.json to
../../.tours/ so it resolves from the video directory to the existing v2/.tours/
location.

In `@v2/start.bat`:
- Line 5: Update the LocalAPI_NetCore command in the startup flow so dotnet
watch receives --no-hot-reload before argument forwarding, while --no-restore is
passed to the Generator application after the separator; use the ordering dotnet
watch run --no-hot-reload -- --no-restore.

Visual Studio CodeTour schema pattern step file highlight exact text matching

💡 Result:

In the Visual Studio CodeTour extension, the "pattern" property in the step schema is designed to associate a tour step with specific line content using a regular expression, rather than an ordinal line number [1][2][3]. Key details regarding the use of the "pattern" property: 1. Functionality: The "pattern" property allows you to define a regex string that the extension will use to find the associated code within the specified file [1][2]. 2. Precedence: The "pattern" property is only evaluated if the "line" property is not set for the step [1][2][3]. If both are provided, the "line" property takes precedence, and the "pattern" is ignored [1][2]. 3. Configuration: You can configure the global recording behavior via the "CodeTour: Record Mode" setting, which can be toggled between "lineNumber" (default) and "pattern" [2][3]. When set to "pattern", the extension will prioritize creating steps based on regex matching when you record new tours [3][4]. To use exact text matching with "pattern", you should escape any special regex characters in your text string to ensure it matches the literal content exactly [1][2]. For authoritative reference, you can consult the official schema located at https://aka.ms/codetour-schema [5][6]. The extension's source code, specifically the step interface definition, confirms "pattern" as a string property on the tour step object [7].

Fix the CodeTour patterns.

The source files contain no match for the regex "this is the code". The steps at lines 16 and 22 cannot highlight their target code. Replace the pattern with stable existing text or omit pattern.

Build DemoLog.csproj before the tour opens the generated file.

The video runner starts the tour before showproj. showproj runs afterward, and its build command is commented out. On a clean checkout, Person_Logging.g.cs under untracked obj/GX may not exist.

Align the README with the checked-in DemoLog sample.

The quick-start section uses AOP.Logging.DependencyInjection and AddTransientWithLogging, but v2/rscg_examples/AOP.Logging.SourceGenerator/src/DemoLog/DemoLog.csproj only references Core, SourceGenerator, and Console, while v2/rscg_examples/AOP.Logging.SourceGenerator/src/DemoLog/Program.cs manually creates DefaultMethodLogger and calls SetMethodLogger.

The sample section also points to ./samples/AOP.Logging.Sample, but the added project is at ./src/DemoLog. Update these instructions or label them as upstream API documentation.

Microsoft dotnet watch option forwarding first unrecognized argument --no-restore --no-hot-reload

💡 Result:

In the dotnet CLI, arguments passed after a double dash (--) are forwarded to the child process (e.g., dotnet run or dotnet test) [1][2][3]. When the double dash is omitted, dotnet watch treats the first unrecognized argument—and all subsequent arguments—as arguments to be passed to the child process [1][2][3]. Regarding your specific options, --no-restore and --no-hot-reload: 1. --no-hot-reload is a native dotnet watch option [1][2]. It is consumed directly by dotnet watch to disable hot reload functionality and is not forwarded to the child process [1][2]. 2. --no-restore is a native option for build-related commands like dotnet run or dotnet build [4]. There are known limitations and nuances when combining these: - dotnet watch consumes its own arguments before forwarding the rest [5]. If you place --no-restore before a double dash, or without a double dash, dotnet watch may not correctly interpret or pass it through as intended, and there have been historical reports of dotnet watch ignoring --no-restore when passed in certain positions [6][7]. - To ensure arguments like --no-restore are correctly received by the child process (e.g., the underlying dotnet run command), you should place them after the -- delimiter [1][2][3]. Example usage: dotnet watch run --no-hot-reload -- --no-restore In this example, --no-hot-reload is handled by dotnet watch, while --no-restore is forwarded to the dotnet run process [1][2]. Using the -- delimiter is the recommended practice to avoid ambiguity and ensure arguments are correctly passed to the child command [2][4][8].

🌐 Web query:

site:learn.microsoft.com/en-us/dotnet/core/tools/dotnet-watch "--no-hot-reload" "unrecognized"

💡 Result:

The error "--no-hot-reload" unrecognized typically occurs when the flag is used with a tool, framework, or version of an application that does not support it [1]. The --no-hot-reload flag is a specific command-line argument used with the dotnet watch tool in.NET to suppress hot reload functionality for supported applications [1]. If you are encountering this error, it is likely due to one of the following reasons: 1. Outdated SDK or Tooling: You may be using an older version of the.NET SDK that does not include the --no-hot-reload option. This option was introduced in later versions of the.NET CLI [1]. Verify your version by running dotnet --version. 2. Incorrect Tool Usage: You might be attempting to pass --no-hot-reload to a different command or a different framework (such as Vite, Next.js, or older versions of React/Webpack) that uses different flags to manage hot reloading (e.g., --no-reload, --disable-live-reload, or environment variables). 3. Incorrect Command Placement: Ensure the flag is placed correctly. For dotnet watch, it should be passed as an argument to the watch command itself (e.g., dotnet watch --no-hot-reload) rather than being appended after the application's command arguments [1]. If you are not working within a.NET environment, check the documentation for your specific development tool or framework to identify the correct flag for disabling hot reloading, as --no-hot-reload is not a universal standard.

🌐 Web query:

dotnet watch source argument parsing no-hot-reload no-restore first unrecognized argument

💡 Result:

In.NET CLI, the dotnet watch command uses a specific argument parsing logic to distinguish between its own configuration options and the arguments intended for the underlying child process (e.g., dotnet run, dotnet test) [1][2][3]. When you provide arguments to dotnet watch without using the double-dash (--) delimiter, the command interprets the first unrecognized argument as the beginning of the arguments to be passed to the child process [1][2][4]. Everything following this first unrecognized argument is forwarded to that child process [3][5]. Key points regarding argument parsing and behavior: 1. Double-Dash Delimiter: The use of -- is optional but highly recommended to explicitly separate dotnet watch configuration (like --no-hot-reload or --no-restore) from child process arguments [1][2][3]. Using it prevents ambiguity where an option intended for the child process might be misidentified as a dotnet watch option, or vice versa [3]. 2. Legacy/Parsing Issues: Historically, older versions of the.NET SDK had issues where dotnet watch would inconsistently parse subcommands or fail to correctly pass arguments, sometimes causing flags (like --no-restore) to be swallowed or incorrectly attributed [6][7]. More recent SDK versions (notably from.NET 8 onwards) have significantly improved this, with rewrites to the parsing logic that ensure clearer separation [8][9]. 3. Forwarded Arguments: When running commands like dotnet watch run --no-restore, the --no-restore flag is interpreted as an argument for the child dotnet run process [9]. If you experience issues where hot reload breaks or flags are ignored, it is often because the argument was not correctly forwarded or the command structure was ambiguous to the parser [9][7]. 4. Best Practice: Always place dotnet watch-specific options (e.g., --no-hot-reload, --verbose) before the -- delimiter, and place all arguments for the target command (e.g., run, test) after it [3]. Example of correct usage: dotnet watch --no-hot-reload -- run --no-restore In this example, --no-hot-reload is processed by dotnet watch, while --no-restore is forwarded to the run command [1][10].

🌐 Web query:

Microsoft Learn dotnet watch --no-restore option list dotnet watch run --no-hot-reload

💡 Result:

The dotnet watch command provides several options to control its behavior, but their usage and effectiveness can vary depending on the specific command being executed and the.NET SDK version in use [1][2]. Regarding --no-restore: While --no-restore is a valid option for many.NET commands (like dotnet run or dotnet build) to skip implicit NuGet package restoration, it is not a direct, supported flag for the dotnet watch command itself [1][3][4]. Users attempting to pass --no-restore to dotnet watch often find that it does not prevent the restore process [5]. Furthermore, there have been documented issues where passing --no-restore via the double-dash delimiter (e.g., dotnet watch run -- --no-restore) fails to effectively bypass restoration in certain SDK versions [6]. Regarding --no-hot-reload: The --no-hot-reload option is a supported, official flag for dotnet watch [7][2]. It is used to disable the Hot Reload feature, which otherwise allows code changes to be applied to a running application without a full rebuild or restart [8][9]. Usage: To disable Hot Reload, you can execute: dotnet watch --no-hot-reload If you need to pass arguments specifically to the underlying command (such as dotnet run), you can use the double-dash (--) delimiter [7][9][2]. For example: dotnet watch run -- --no-hot-reload For the most up-to-date behavior regarding command-line options and potential limitations in your specific SDK version, it is recommended to consult the official Microsoft Learn documentation for the dotnet watch command [1][2].

Citations:


Move --no-hot-reload before the forwarded arguments.

--no-restore is not a dotnet watch option. It starts forwarding, so --no-hot-reload reaches the Generator application and does not disable hot reload.

Use dotnet watch run --no-hot-reload -- --no-restore.
