String matching on `\w*EventArgs` is sufficient because all Web Forms EventArgs subtypes follow the naming convention `*EventArgs`. This avoids false positives on non-EventArgs types like `string` or `int`. +**Risk:** If a custom EventArgs subclass is named exactly `EventArgs` (impossible per C# rules) it would be incorrectly stripped. Extremely low risk. + +### D2: GAP-05 Lifecycle — `await base.OnInitializedAsync()` injection +**Decision:** Inject `await base.OnInitializedAsync();` at the start of the converted `OnInitializedAsync` body. +**Rationale:** Blazor requires calling the base lifecycle method. Missing this call is a common source of bugs when components use `WebFormsPageBase` which has initialization logic in the base. + +### D3: GAP-05 PreRender — `if (firstRender)` guard wrapping +**Decision:** Wrap the entire `Page_PreRender` body in `if (firstRender) { ... }` when converting to `OnAfterRenderAsync`. +**Rationale:** `Page_PreRender` runs once before the first render. `OnAfterRenderAsync` runs after *every* render. The `firstRender` guard preserves the original single-execution semantics. + +### D4: Transform ordering — Lifecycle before Event Handlers +**Decision:** Run GAP-05 (lifecycle) before GAP-07 (event handlers) in the pipeline. +**Rationale:** Lifecycle conversion changes `Page_Load(object sender, EventArgs e)` to `OnInitializedAsync()`.

Security Considerations + +### Why C# Over PowerShell + +Jeff's core motivation: **reduce injection surface.** + +- **No `Invoke-Expression`**: PowerShell scripts can be tricked into evaluating user input. The C# tool uses compiled regex patterns — no dynamic code execution. +- **No environment variable interpolation in transforms**: All regex patterns are compile-time constants or `Regex.Escape()`d inputs. +- **Signed NuGet package**: The tool ships via NuGet with package signing, establishing provenance. +- **No shell-out**: The tool does not invoke any external processes. Everything is in-process C#. + +### Input Validation + +```csharp +public static class PathValidator +{ + public static string ValidateInputPath(string path) + { + var resolved = Path.GetFullPath(path); + if (!Directory.Exists(resolved) && !File.Exists(resolved)) + throw new FileNotFoundException($"Input path not found: {path}"); + + // Prevent path traversal + if (resolved.Contains("..")) + throw new ArgumentException("Path traversal not allowed"); + + return resolved; + } + + public static string ValidateOutputPath(string path, string inputPath) + { + var resolved = Path.GetFullPath(path); + + // Prevent writing outside intended directory + // (no writing to system directories, etc.) + if (resolved.StartsWith(Path.GetTempPath(), StringComparison.OrdinalIgnoreCase)) + throw new ArgumentException("Cannot write to temp directory"); + + return resolved; + } +} +``` + +### Content Safety + +- **No `eval` or `CSharpScript`**: All transforms are regex-based string operations. +- **No deserialization of untrusted data**: The tool reads `.aspx`/`.cs` files as plain text. No XML deserialization of user controls (we regex-match, not parse). +- **web.config XML parsing**: Uses `XDocument` (LINQ to XML) which is safe against XXE by default in .NET. +- **Output encoding**: All files written as UTF-8. No content injection via file names — output paths are sanitized through `Path.GetFileName()`. + +### NuGet Signing + +```xml + + true + false + +``` + +The CI pipeline should sign the NuGet package with a code signing certificate before publishing to nuget.org. + +--- + +## Appendix A: Transform Ordering (Markup Pipeline) + +The exact ordering from `Convert-WebFormsFile` in the PowerShell script, preserved in the C# pipeline: + +| Order | Transform | Why This Position | +|-------|-----------|-------------------| +| 100 | PageDirective | Must run first — extracts route, emits @page | +| 110 | MasterDirective | Removes <%@ Master %> | +| 120 | ControlDirective | Removes <%@ Control %> | +| 200 | ImportDirective | <%@ Import %> → @using | +| 210 | RegisterDirective | Removes <%@ Register %> | +| 300 | ContentWrapper | asp:Content → strip/HeadContent | +| 310 | FormWrapper | `
