Question

We write an application with WPF. When we build this project, 3 files is generate for us in addition to :

> OurApplication.exe
> OurApplication.exe.config

their names are:

> OurApplication.vshost.exe
> OurApplication.vshost.exe.config
> OurApplication.vshost.exe.manifest

first, what are these files? secondly, which one of this config files are primary? If we delete these 3 files, can we running application?

Answer 1

first, what are these files?

The vshost.exe files are hosting executables for use in debugging. They are used to improve debugging performance, enable partial-trust debugging and give you design-time expression evaluation in the Immediate window.

secondly, which one of this config files are primary?

None. The primary config for your application OurApplication.exe should be OurApplication.exe.config. If you’ve added an App.config configuration file to your project the build process will automatically generate OurApplication.exe.config using this file unless you’ve changed a build setting.

If we delete these 3 files, can we running application?

Yes. These are for debugging purposes only; you do not need them to run your application and should not deploy them with your application.
