hi i just started developing in vs2008 and i found out that lots of .tmp files generated ..... is this normal ? Or is there a patch that i should download

Im pretty sure this is normal and that the files are created to assist with faster development including debugging and running your development server as each time you run your application your code is converted.

I have found by cleaning my system out it takes awhile to reload projects as the code needs to be regenerated - again this is the .tmp files you have described. With out the .tmp files I would think it would be very difficult and extremly slow to get anything done and defeat the purpose of the new 2008 release.

 hmmm does this mean i should them manually...?

Did you mean tmp files appear in the Solution Explorer? there was a thread on this: http://forums.asp.net/t/1197597.aspx

well in my case , my machine is clean, no previous visual studio is installed. NO third party whatsoever only Microsoft products in my machines. AM i one the few experiencing this ..
