C# Executable File

Question

Hi Experts,

It was great day for me Yesterday.. Created my First Executable Project and the Application is in
live now. The application has been installed in the end users system and now facing some issues like
modifications to Applications.

And my requirement is, once the modifications to Application are made, How can I distribute the EXE changes
to the user ??

Is that I need to generate the EXE again ?

Is it Possible to maintain the EXE centrally or in Share  ?

Thanks in Advance
