Windows Service Application exe file not updating

Question

Hi,

 

      In my windows service I am performing Uninstall programatically if already service exists and then install the new version using msi.

 

But now what happens is it Uninstalls the previous version and then installs the new build. But the code change is not updated.

 

I see last modifed date of Application exe as yesterday. So it is not updated.

 

The config and state file is updated.

 

Any help please.

 

Thanks,

Rajee
