Description
What happened?
Using the WinRT API Windows.Storage.FileIO.writeTextAsync from java script in webview2 throws "The system cannot find the file specified 0x80070002" even that the file exists.
Some times it throws "The process cannot access the file because it is being used by another process. (0x80070020)" which is expected but the 0x80070002 is not correct.
Also tested the same behaviour is webview1 and it never throws anything!.
let root = Windows.Storage.ApplicationData.current.localFolder;
root.createFileAsync("fileName", Windows.Storage.CreationCollisionOption.openIfExists).then((file) => {
Windows.Storage.FileIO.writeTextAsync(file, "data 1")
console.log('data 1 saved');
})
root.createFileAsync("fileName", Windows.Storage.CreationCollisionOption.openIfExists).then((file) => {
Windows.Storage.FileIO.writeTextAsync(file, "data 2")
console.log('data 2 saved');
})
