This is currendly only intended to demonstrate issues with the MAUI Gtk platform and not for active development as changes in the container would get lost on a podman build. I'm working on a devcontainer setup to have the maui folder mounted as a podman volume to persist changes to the codebase.

After git-cloning and cd into the repo, build the image:

sudo podman build -t maui-env .

# Clear cache
sudo podman build --no-cache -t maui-env .

This will build MAUI along with GtkSharp already. Then start the container (which can take a minute) using:

xhost +  # allow container to use the X display of the host
sudo podman run -it --rm -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix maui-env bash
xhost -  # restrict display access again

Alternatively, use Visual Studio Code to handle the display and have a deeper look at the MAUI sources:

• Start VS Code in a new bash outside the container with code .,
• then install VS Codes 'Dev Containers' and 'Docker' extension. After that,
• in the 'Containers' item of side panel start the 'maui-env' container and right click / attach it to VS Code,
• then click the generated container name at the top.
• In the newly opened Code window, wait a few seconds until VS Code is setup in the container.

Finally open folder /mauienv/maui-linux/ and enter these commands in VS Codes terminal window:

cd /mauienv/maui-linux/src/Controls/samples/Controls.Sample
dotnet run --framework net8.0-gtk

Also have a look at

cd ../Controls.Sample.Gtk
cp ../Controls.Sample/Resources/Images/calculator.png ./dotnet_bot.png  # someone forgot to git add the image
dotnet run
