Web Application project now has "output type of Class Library"

[gdrenfrew]

Hi there,
I've been working on a Web Application project with asp.net and vb.net objects in the back, and it's been going ok and I can debug it etc.

However, I tried to debug it this evening and now get there error:
"A project with output type of Class Library cannot be started directly".

It advises changing the project properties/Start Action to
"Start External Program" or "Start URL".

When I look at my project properties, sure enough it says Output Type: Class Library , and the Output Name is Project1.DLL. There is no other option in the Output Type dropbox.

I haven't had this issue before and wonder what has changed (this evening I added some modules and a class, but didn't fiddle with any settings).
Can someone please advise a newcomer to .net on how to get my project debugging again?

Best regards
and thanks in advance
Graeme

Even though I had WebPage.aspx set as "Set as Start Page", I had a component project as "Set as Startup Project".

Have to set my web projected as startup project.
