Input File is modified after output file - Visual Web Developer 2013

Hi,,

Ive been using VWD 2013 for a while now, but all of a sudden, when compiling/running the project, im getting the below error:

Input file 'C:\greptech\trunk\greptechMVC\bin\greptechMVC.dll' is modified after output file 'C:\greptech\trunk\greptechMVC\bin\greptechMVC.pdb'.

I have backed out all my changes and reverted to my original code, but i still get this error. Only when i close VWD and restart it and open the project will it then run fine with no issues. When i start making changes to the various files, and run the web project, it gives me the above error again.

I have been checking online for a while now, but nothing has worked. 

Can someone please assist me.

Thanks,

Naren
