Isolating Office Extensions with the COM Shim Wizard

This article explains the importance of using a shim when implementing managed extensions for Office. It also provides a wizard to easily generate the shim from the managed extension. Very recommendable.

Problem with NAnt's xmlpoke task

There's an issue when trying to replace some part of an xml file that is under a default namespace using NAnt’s xmlpoke task. It happened to me the other day when trying to replace the version attribute in the following wix file:

<?xml version="1.0" encoding="utf-8"?>
<Wix xmlns="http://schemas.microsoft.com/wix/2003/01/wi">
<Product Name="MyProduct" Id="847A8D24-0F98-4b9f-AEA0-070ABD49F86C" Language="1033" Codepage="1252" Version="1.0.0" Manufacturer="MyCompany">

Because of the namespace definition in the Wix element, calling xmlpoke simple as
<xmlpoke file="${wix.file}" xpath="/Wix/Product/@Version" value="${build.new.version}"/>
does not work.

What it does work is the following use of the task:

<xmlpoke file="${wix.file}" xpath="/wx:Wix/wx:Product/@Version" value="${build.version}">
<namespace prefix="wx" uri="http://schemas.microsoft.com/wix/2003/01/wi" />


NAnt Contrib is a project that contributes with a lot of additional tasks to NAnt. For example, two of the most useful tasks for me are the trycatch and choose tasks.
