DropBox API Async Call, "DropBoxClient.Files.DownloadAsync" will not throw an exception (solution)

I just tried running a stripped down version of this code in the same environment (using v5.0.0 of the Dropbox .NET SDK, in a project using VB.NET and .NET Framework 4.6.1 in Visual Studio 2019) and it works correctly for me. I'm able to trigger and catch an exception from DownloadAsync for a non-existant path.

Here's the simplified code:

    Private Async Sub Test()

        Console.WriteLine("Running Test...")

        Dim loDropBoxClient               As DropboxClient
        Dim loDropBoxClientResponse       As Object

        Dim csDropBoxUserAccessToken = "<ACCESS_TOKEN>"

        Try

            loDropBoxClient = New DropboxClient(csDropBoxUserAccessToken)

            loDropBoxClientResponse = Await loDropBoxClient.Files.DownloadAsync("/nonexistantpath")
            Console.WriteLine("Got response:")
            Console.WriteLine(loDropBoxClientResponse)

        Catch loDropboxException As DropboxException
            Console.WriteLine("Got DropboxException:")
            Console.WriteLine(loDropboxException)
        Catch loException As Exception
            Console.WriteLine("Got Exception:")
            Console.WriteLine(loException)

        End Try

        Console.WriteLine("Test complete.")
        Console.ReadLine()

    End Sub

Could you give that a try and let me know the issue does or doesn't reproduce with that for you?
