How to Edit an App Manifest File for Visual Studio 2010 and Newer Versions

Introduction

The Manifest file is an XML file that defines various aspects of your application, including its identity, version, and security settings. Editing the Manifest file allows you to customize these settings to meet the specific requirements of your application.

Creating/Editing a Manifest File

In Visual Studio 2010 and subsequent versions, you can easily add a Manifest file to your project:

1. Right-click on your project file in the Solution Explorer.
2. Select "Add" then "New Item" (or press Ctrl Shift A).
3. In the "Add New Item" dialog, select "Application Manifest File."

This will create an app.manifest file in your project directory. You can open this file in the XML editor and make necessary changes.

Example Code

The following code is an example of a simplified Manifest file that includes an elevation requirement:

<?xml version="1.0" encoding="utf-8"?>
<assembly manifestversion="1.0" xmlns="urn:schemas-microsoft-com:asm.v1" xmlns:asmv1="urn:schemas-microsoft-com:asm.v1" xmlns:asmv2="urn:schemas-microsoft-com:asm.v2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <assemblyidentity version="1.0.0.0" name="MyApplication"></assemblyidentity>
    <trustinfo xmlns="urn:schemas-microsoft-com:asm.v2">
        <security>
            <requestedprivileges xmlns="urn:schemas-microsoft-com:asm.v3">
                <requestedexecutionlevel level="requireAdministrator" uiaccess="false"></requestedexecutionlevel>
            </requestedprivileges>
        </security>
    </trustinfo>
</assembly>

This Manifest file specifies that the application requires administrator privileges to run.

Additional Considerations

• It's important to note that not all project types support Manifest files. For example, web applications do not allow them.
• Be careful when modifying the Manifest file, as incorrect changes can result in deployment errors.
• For more information on editing Manifest files, refer to the Microsoft documentation: https://docs.microsoft.com/en-us/windows/win32/manifests/manifest-files
