# The release: a tag of the form v1.2.3.0 builds the solution, runs the tests
# and packs the MSIX with the version taken from the tag.
#
# The same requirements to the runner as in pull-request.yml apply: Windows, the
# .NET 10 SDK and an interactive desktop session for the tests. makeappx comes
# with a NuGet package (Packaging\Tools\SdkTools.csproj), so the Windows SDK does
# not have to be installed.
