C++/WinRT Console: Initializing BackgroundDownloader crashes the program

I recently started playing with C++/WinRT (https://marketplace.visualstudio.com/items?itemName=CppWinRTTeam.cppwinrt101804264).

My goal is to create an app that downloads a file and saves it to the downloads folder. I decided to use BackgroundDownloader class (https://learn.microsoft.com/en-us/uwp/api/windows.networking.backgroundtransfer.backgrounddownloader?view=winrt-19041).

However, when I try to create BackgroundDownloader instance my program crashes with the following exception: Exception thrown at 0x76729AB2 in MyApp.exe: Microsoft C++ exception: winrt::hresult_error at memory location 0x004FEEF4.


int main()
{
   // The line bellow causes the crash:
   winrt::Windows::Networking::BackgroundTransfer::BackgroundDownloader backgroundDownloader;
}

What did I wrong?

WinRT is a bunch of COM interfaces so you need to initialize the subsystem first. You must initialize the WinRT apartment first like this

winrt::init_apartment();

or

winrt::init_apartment(apartment_type::single_threaded);

for UI applications
