How to Create and Edit an Application Manifest File in Visual Studio?

Creating/Editing a Manifest File in Visual Studio

Creating or editing a Manifest file is a simple process that enhances the functionality of your projects. Here's a step-by-step guide:

In Visual Studio:

1. Right-click on the desired project file in the Solution Explorer.
2. Select "Add," then "New Item."
3. In the displayed window, search for "Application Manifest File."
4. Enter a file name (typically "app.manifest") and click "Add."

Embedding Existing Code

To add existing code to your newly created manifest file:

1. Open the "app.manifest" file in a text editor.
2. Locate the appropriate section within the XML code, such as the assemblyIdentity element for version or name changes.
3. Paste the provided code into the desired location.

Example:

The following code snippet elevates privileges for an application:

<asmv1: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" />
    <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
        <security>
            <requestedPrivileges xmlns="urn:schemas-microsoft-com:asm.v3">
                <requestedExecutionLevel level="requireAdministrator" 
        uiAccess="false" />
            </requestedPrivileges>
        </security>
    </trustInfo>
</asmv1:assembly>

1. In the "app.manifest" file, locate the "trustInfo" element.
2. Paste the above code within the "trustInfo" element.

Note:

• The element names and attributes are case-sensitive.
• Always double-check the syntax and structure of the XML code before saving.
