language
<trustInfo> Element Identifies the application security requirements. None
<entryPoint> Element Required. Identifies the application code entry point. name
<dependency> Element Required. Identifies each dependency required for the application to run. Optionally identifies assemblies that need to be preinstalled. None
<file> Element Optional. Identifies each nonassembly file that is used by the application. Can include Component Object Model (COM) isolation data associated with the file. name

Remarks

The ClickOnce application manifest file identifies an application deployed using ClickOnce. For more information about ClickOnce, see ClickOnce Security and Deployment.

File location

A ClickOnce application manifest is specific to a single version of a deployment. For this reason, they should be stored separately from deployment manifests. The common convention is to place them in a subdirectory named after the associated version.

The application manifest always must be signed prior to deployment. If you change an application manifest manually, you must use mage.exe to re-sign the application manifest, update the deployment manifest, and then re-sign the deployment manifest. For more information, see Walkthrough: Manually deploy a ClickOnce application.

File name syntax

The name of a ClickOnce application manifest file should be the full name and extension of the application as identified in the assemblyIdentity element, followed by the extension .manifest. For example, an application manifest that refers to the Example.exe application would use the following file name syntax.

example.exe.manifest

Example

The following code example shows an application manifest for a ClickOnce application.
