Read this Create, write, and read a file topic about interaction with file in UWP .

To write string to StorageFile use FileIO.WriteTextAsync or FileIO.AppendTextAsync functions

Dim file As StorageFile = Await ApplicationData.Current.LocalFolder.CreateFileAsync("file.txt", CreationCollisionOption.ReplaceExisting)
Dim strData As String = "sample text to write"
Await FileIO.WriteTextAsync(file, strData)
