Application manifests for Office solutions

  • Article

An application manifest is an XML file that describes the assemblies that are loaded into a Microsoft Office solution. The Microsoft Office development tools in Visual Studio use the ClickOnce application manifest schema defined in the ClickOnce application manifest reference.

Application manifests for Office solutions use the following ClickOnce elements and attributes.

Element Description Attributes
<assembly> Element (ClickOnce Application) Required. Top-level element. manifestVersion
<assemblyIdentity> Element (ClickOnce Application) Required. Identifies the ClickOnce application's primary assembly. name

version

publicKeyToken

processorArchitecture

language
<trustInfo> Element (ClickOnce Application) Identifies the application security requirements. None
<entryPoint> Element (ClickOnce Application) Required. Identifies the application code entry point for execution. name

dependencyName

customHostSpecified
<dependency> Element (ClickOnce Application) Required. Identifies each dependency required for the application to run. Optionally identifies assemblies that need to be preinstalled. None
<file> Element (ClickOnce Application) Required. Identifies each non-assembly file that is used by the application. Can include Component Object Model (COM) isolation data associated with the file. name

size

Application manifests for Office solutions have the following element in the co.v1 namespace.

<entryPoint>

Remarks

You can manually edit application and deployment manifests in Office solutions. Afterwards, you must re-sign the application and deployment manifests by using the Manifest Generation and Editing Tool (mage.exe and mageui.exe). For more information, see How to: Re-sign application and deployment manifests.

File location

An application manifest is specific to a single version of a solution. For this reason, application manifests should be stored separately from deployment manifests. Visual Studio places the version-specific files in a subdirectory named after the associated version in the Application Files subdirectory in the publish folder.

File name syntax

The name of an 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 OutlookAddIn1.dll customization would use the following file name syntax.

OutlookAddIn1.dll.manifest
