A Net Framework question

>>How does it happen and how can I remove the message box?

OK:
Why - a project is set to use the 2.0 net framework.
How to stop it - change the project settings to use the 3.5 framework.

Now save it and replace your older copy with the newer copy.

ps.  A Winword doc is a format that can be used to carry malware - try to use a picture (eg. jpg) format rather than a doc file to show the message.

Thanks for comments.

Sure it's like this. I mean where to set or to change?

Actually I ony have one copy which is old and new.

Thanks.

Doesn't answering Yes to the prompt correct it? It did on my own projects.

I don't have any copy of VS2008 in my environment, but in VS2010, you can change the target framework through the Build tab of the Property Pages for the site, available through the context menu of the Web Site in the Solution Explorer, or Shift-F4 in the default keyboard setting.

Thank you both a lot. I'm using 2008. I got a different screen.
