c# - How to check if file exists in a Windows Store App?

Question

Is there any other way of checking whether a file exists in a Windows Store app?

try
{
    var file = await ApplicationData.Current.LocalFolder.GetFileAsync("Test.xml");
    //no exception means file exists
}
catch (FileNotFoundException ex)
{ 
    //find out through exception 
}

According to the accepted answer in this post, there is no other way at the moment. However, the File IO team is considering changing the the api so that it returns null instead of throwing an exception.

Quote from the linked post:

Currently the only way to check if a file exists is to catch the FileNotFoundException. As has been pointed out having an explicit check and the opening is a race condition and as such I don't expect there to be any file exists API's added. I believe the File IO team (I'm not on that team so I don't know for sure but this is what I've heard) is considering having this API return null instead of throwing if the file doesn't exist.
