Why is my ASP.NET app slow the first time after building a class library?

build

Hi all

I've got a web app solution containing a class library project.

Whenever I rebuild the class library and then refresh the page, it takes ages the first time, and is then quick again subsequently.

It's almost as if the newly rebuilt dll is having to 'bed in' to the app.

Can anyone tell me what's really going on behind the scenes?

Thanks

David
