Syncfusion WinForms PdfViewer - UI Sample generator

Generate C# Code for the User's Project (default)

Trigger keywords: "code", "snippet", "how to write", "Program.cs", "show me", "sample", "integrate", "example code", "generate code for", "create sample", "winforms pdfviewer".

Purpose: Generate clean, ready-to-use C# code snippets that directly insert into their WinForms application when working with Syncfusion WinForms PdfViewer control.

Workflow:

Build the C# code using the snippets provided in the references/*.md files.
Before generating the sample, ask the user whether the code should be:Integrated into an existing WinForms project, or Created as a new WinForms application.
If the user chooses to create a new WinForms project, ask them which target framework they want to use: -.NET Framework (e.g., 4.6, 4.7, 4.8) — uses Syncfusion.PdfViewer.WinForms and targets the classic .NET Framework. -.NET / .NET Core (e.g., .NET 8, .NET 10) — uses Syncfusion.PdfViewer.WinForms with <TargetFramework>net8.0-windows</TargetFramework> (or the selected version).
Based on the user's choice: Generate the .csproj file with the correct <TargetFramework> value. Add the required NuGet packages. Tailor any framework-specific code, such as namespace imports, form initialization, startup code (Program.cs), and PDF Viewer setup, accordingly.
Add only the APIs required to satisfy the user's requested functionality. Do not include optional APIs, additional.

saving-pdf-files.md	Save PDF via toolbar, programmatic save using `LoadedDocument.Save()`, `BeginSave` and `EndSave` events
printing-pdf-files.md	Print PDF via toolbar, silent printing using `Print()`, customize print size (`ActualSize`, `Fit`, `CustomScale`), print orientation (`Auto`, `Portrait`, `Landscape`), hide print status dialog, `BeginPrint`, `PrintProgress`, and `EndPrint` events
extract-text.md	Extract text from a single page using `ExtractText(pageIndex, out textLines)`, extract text from entire file using `PageCount` loop, extract text with line bounds via `TextLines`/`TextLine`, extract words with bounds via `WordCollection`/`TextWord`

navigation.md	Bookmark navigation, hyperlink handling, and page navigation (programmatic `GoToBookmark()`, `HyperlinkClicked`/`HyperlinkMouseOver`, `GoToPageAtIndex()`)
localization.md	Localize tooltip and context menu static text, default `en-US` localization keys table, add culture-specific Resx files (e.g., `Syncfusion.PdfViewer.Windows.fr.resx`), set custom assembly/namespace for localization using `LocalizationManager.SetResources()`

error-handling.md	Subscribe to `ErrorOccurred` event, handle `ErrorOccurredEventArgs.Message` to log errors or display messages to users
magnifying.md	Zoom to a specific percentage using `ZoomTo()`, get current zoom via `ZoomPercentage`, switch zoom modes using `ZoomMode` property (`FitPage`, `FitWidth`)
view-pdf-stream.md	Load a PDF from a `FileStream` using the `Load(stream)` overload
document-information.md	Access filename and file path of the loaded PDF via `DocumentInformation.FileName` and `DocumentInformation.FilePath`; get page count via `PageCount`
