How do I create/edit a Manifest file?

Question

In Visual Studio 2010 (until 2019 and possibly future versions) you can add the manifest file to your project.

Right click your project file on the Solution Explorer, select Add, then New item (or CTRL+SHIFT+A). There you can find Application Manifest File.

The file name is app.manifest.

As ibram stated, add the manifest thru solution explorer:

This creates a default manifest. Now, edit the manifest.

• Update the assemblyIdentity name as your application.
• Ask users to trust your application

• Add supported OS

The simplest way to create a manifest is:

Project Properties -> Security -> Click "enable ClickOnce security settings" 
(it will generate default manifest in your project Properties) -> then Click 
it again in order to uncheck that Checkbox -> open your app.maifest and edit 
it as you wish.

In Visual Studio 2019 WinForm Projects, it is available under

Project Properties -> Application -> View Windows Settings (button)
