Python WinUI Tic-Tac-Toe (code-only)

A polished, playable 3x3 Tic-Tac-Toe sample built entirely in Python with generated WinUI 3 projections. Application, Window, every layout object, grid definition, control, event handler, and game-state transition is created programmatically. The sample uses the default Fluent control resources and constructs a Mica system backdrop through its generated composable projection; it does not load or register XAML.

Prerequisites

• Windows 11 on x64 with CPython 3.11–3.14.
• WinApp CLI 0.6.2 or newer.
• dynwinrt installed in the Python interpreter used to run the sample.
• Matching dynwinrt and dynwinrt-codegen versions.

Install the published preview packages:

python -m pip install --pre dynwinrt dynwinrt-codegen

For source-checkout development, build dynwinrt-codegen and install the runtime with python -m maturin develop --release from bindings\py instead.

Restore the pinned Windows App SDK, generate the Python projection, and run:

winapp restore
.\generate.ps1
.\run.ps1 -Python C:\path\to\python.exe

winapp restore prepares the pinned SDK metadata and bootstrap binaries under .winapp\. generate.ps1 uses that metadata to generate Python bindings and copies the selected architecture's bootstrap DLL to .runtime\. Before calling init_winappsdk(2, 3), app.py sets WINAPPSDK_BOOTSTRAP_DLL_PATH to that local copy.

Pass -Codegen ..\..\..\target\release\dynwinrt-codegen.exe when testing a source build.

Players alternate selecting cells. Choose New game after a win or draw to reset the board. Closing the window exits the WinUI application and releases projected objects deterministically.

generated\, .runtime\, and Python caches are local artifacts and are not tracked.
