[WiX-users] Trying to use the EventSource element gives "component element contains an unhandled extension element" error

[Patrick v. d. V. <pet...@gm...>]

Hi All

I'm trying to build a simple installer but I'm getting the following error:

   The Component element contains an unhandled extension element
'util:EventSource'.  Please ensure that the extension for elements in the '
http://schemas.microsoft.com/wix/UtilExtension ' namespace has been
provided.

I'm using the VS2010 shell with the latest weekly build of Wix 3.6
installed. In my project I've referenced:
- WixNetFxExtension
- WixUtilExtension

And my wxs file looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi"
     xmlns:util="http://schemas.microsoft.com/wix/UtilExtension "

    <?include $(var.CurrentProjectDir)\Dependencies.wxi ?>

    <Fragment>
        <DirectoryRef Id="INSTALLLOCATION">
            <Component Id="C.Apollo.Core.Dataset.Exe"
                       Guid="{BCB6762B-3F74-41A7-A45F-7C664E9ED425}">
                <File Id="File.Apollo.Core.Dataset.Exe"
                      Name="Apollo.Core.Dataset.exe"
                      DiskId="1"

Source="$(var.Apollo_BinFolder)\Apollo.Core.Dataset.exe"
                      KeyPath="yes" />

                <!-- EventLog -->
                <util:EventSource Log="Application"
                                          Name="Apollo.Core.Dataset"

EventMessageFile="[NETFRAMEWORK40FULLINSTALLROOTDIR]EventLogMessages.dll" />
            </Component>
        </DirectoryRef>

        <!-- The feature for the main program. -->
        <ComponentGroup Id="CGroup.Apollo.Core.Dataset">
            <ComponentRef Id="C.Apollo.Core.Dataset.Exe" />
        </ComponentGroup>
    </Fragment>
</Wix>

>From what I can tell I have done all that I need to do, however the compiler
seems to disagree with me. I'm sure it is correct however I don't have any
idea what it wants me to do. Can anybody point me in the right direction?

Thanks

Patrick
