Web Deployment Error

Hello,

I created a Web Deployment project to build an Asp.Net 3.5 web site.

Everything was working but then I needed a few extra tasks. So I found
the following:

http://msbuildtasks.tigris.org/

I installed the file and I added the import code line to my Web
Deployment project file:

-->




...

When I save my project file I get an error on the code line:


A window opens with the following message:

"The project file could not be loaded. There are multiple root
elements."

Could someone tell me what I am doing wrong?

Thanks,

Miguel
