How do I create/edit a Manifest file?

In Visual Studio 2010 and possibly in 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.

If this item doesn't exist then your project type is not conform with a manifest file, e.g. web application.

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
