Unable to generate a temporary class (result=1).

I am getting an error message saying " Unable to generate a temporary class (result=1)." when i am trying to load home page. I have checked out whole error and have come across below 2 suspicious error codes:
error CS2001: Source file 'C:\WINDOWS\TEMP\iaghoo7i.0.cs' could not be found
error CS2008: No inputs specified
Is there a fix for this??

I am aware of this error and i will like to inform you that it is because of security permissions on c:\windows\temp. In order to get rid of that error message just change permissions for asp.net user.
