How to generate an .EXE with different Name than the main Assembly?

Question

I have a WPF application with lot of XAML code referencing the main assembly (for widgets, styles and these things).

But now I need to change the name of the .EXE, but not its source main assembly for not updating so many dependencies.

How to do it as simple as possible?

Answer 1

Go to the project's properties and change "Assembly name" setting on the "Application" tab:

Answer 2

You just need to change the file name after the build? You could use a post-build script.
