Why an ASP.NET web site gets recompiled when renaming or deleting a folder inside

Question

Hi everybody,

I develop a simple file manager inside an ASP.NET Web site (not web application).

I notice that every time I rename or delete a folder, the site gets recompiled - i.e. the very next web request after delete or rename operation takes considerably much time to execute.

It's only true for folders, not for files. Why does this occur?

P.S. I use WebDev server (Cassini), haven't tested in on IIS yet.

UPDATE: The same disaster happens with ASP.NET MVC Web Applications :(

UPDATE 2: Here are similar discussions:

Answer 1

Where are the folders you are creating? Under App_Data?

Answer 2

Asp.net watches the folders and then runs compilation to keep up with any changes you make. To overcome this you can use Non-updateable full precompilation, which you can read about here.
