Is it possible to convert Windows::Foundation::IAsyncOperation<T> to Concurrency::task<T>? - c++-winrt

Question

As in the question, is it possible to convert between Windows::Foundation::IAsyncOperation and Concurrency::task?
If so, how to do it?
Update 1.
I'm migrating from C++/CX to C++/winrt and I have the following constructor in C++/CX code:
XamlComponentConstructor:XamlComponentConstructor()
{
InitializeComponent();
Uri^ uri = ref new Uri(L"URI");
create_task(StorageFile::GetFileFromApplicationUriAsync(uri))
.then([this](StorageFile^ file)
{
return Windows::Storage::FileIO::ReadTextAsync(file);
})
.then([this](Platform::String^ text)
{
// Text processing
x_firstTextBox->Text = var1;
x_secondTextBox->Text = var2;
})
}
The main problem is that there is no possibility to use corutines in the class constructor.
So the following code doesn't work:
XamlComponentConstructor:XamlComponentConstructor()
{
InitializeComponent();
const auto uri = winrt::Uri(L"URI");
const auto file { co_await StorageFile::GetFileFromApplicationUriAsync(uri) };
const auto text { co_await winrt::FileIO::ReadTextAsync(file) };
//Text processing
x_firstTextBox->Text = var1;
x_secondTextBox->Text = var2;
}
Do you have any idea how to change this code to work?

Answer 1

you can call do like following code.
XamlComponentConstructor:XamlComponentConstructor()
{
InitializeComponent();
const auto uri = winrt::Uri(L"URI");
StorageFile::GetFileFromApplicationUriAsync(uri).Completed(
[this](auto const& res, AsyncStatus const status)
{
StorageFile file { res.GetResults() };
winrt::FileIO::ReadTextAsync(file).Completed[this](
auto const& res, AsyncStatus const status)
{
auto text = res.GetResults();
//your code
}
}
);
}
