Validate the extension manifest

The contents of the extension manifest file (.aaPLUGIN) can be validated from inside the Visual Studio.NET IDE using the steps explained below:

1. Copy the IDE Extensions Xml Schema.xsd file to schemas folder under the Visual Studio.NET IDE installation path. Typically, this will be C:\Program Files\Microsoft Visual Studio .NET 2003\Common7\Packages\schemas\xml.

2. Select the aaPLUGIN manifest file in the project tree and right-click.

3. Select “Open with…” command.

4. In the window that is shown, select HTML/XML editor.

5. Select 'Set As Default'. This will make it open the aaPLUGIN file in XML editor by default.

6. Select 'Open'.

7. Modify the <Root> tag to the following:

   <Root xmlns="http://wonderware.com/aaide.xsd">

8. From the XML top-level menu, select the ‘Validate XML data’ command to validate the contents. Fix errors if any.
