In .Net, using File.CreateText () also blocks the file, why?

Question

I used the CreateText method to create an empty file (as shown below) in "App1". Then I tried to write another application to this file, but it failed b / c, it was blocked. It was not unlocked until I closed "App1"

File.CreateText(path)

To fix this, I can do this:

Dim sw As StreamWriter = File.CreateText(path)
sw.Close()

Why does calling only CreateText lock the file? Is there any implicit stream or script file or something created?
