This is a repository that contains a sample project that shows a build regression after updating CppWinRT from 2.0.221104.6, which build this repository, to 2.0.221117.1, which no longer builds the repository, with the following error:
1>------ Build started: Project: TestBuildCppWinRT, Configuration: Debug x64 ------
1>pch.cpp
1>C:\prog\janeasystems\TestBuildCppWinRT\x64\Debug\Generated Files\winrt\impl\Windows.Graphics.Capture.0.h(27,12): error C3312: no callable 'await_resume' function found for type 'winrt::Windows::System::DispatcherQueue'
1>(compiling source file 'pch.cpp')
1>Done building project "TestBuildCppWinRT.vcxproj" -- FAILED.
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
This sample is updated all the way up until the latest CppWinRt version at this time, 2.0.240111.5, which still doesn't build this code:
inline winrt::fire_and_forget ShutdownAndThenPostQuitMessage(winrt::Windows::System::DispatcherQueueController const& controller, int exitCode)
{
auto queue = controller.DispatcherQueue();
co_await controller.ShutdownQueueAsync();
co_await queue; // This line no longer builds.
PostQuitMessage(exitCode);
co_return;
}The code is taken from https://www.nuget.org/packages/robmikh.common/0.0.22-beta package, from this file: https://github.com/robmikh/robmikh.common/blob/aaa31a1bcd4fac19ce4c544d2cfd415612add7f0/robmikh.common/include/robmikh.common/dispatcherqueue.desktop.interop.h
CppWinRT 2.0.221104.6 builds this code. This repo can be build at this commit: https://github.com/jaimecbernardo/Sample-CppWinRT-DispatcherQueue-build-regression/commit/c1a7221f9eeb6dab8a16fa6b812d97eb5132902c
