Creating Windows Installer Patch files with VS.NET

[Angelos Karantzalis]

Hi y'all,

only recently, I've delved into creating installers with VS.NET. So far, I'd
created a Deployment Solution, added a couple of Merge Modules to it &
everything worked fine.

Today, I read some stuff on MSDN that talked about Windows Installer Patch
files, but nowhere did I find any info regarding creating WIP files with
VS.NET.

Is it the case that with a WIP I could patch/update the contents that were
originaly in a Merge Module in my first MSI?
Is there any other way to update what was originally in a merge module in
the first msi?

In short, if I'd used a deployment project with 4 merge modules to deploy an
app & four components, is there a way to create some sort of
installation/patching file, updating/patching only one of the installed
components without un-installing the application?

Cheers,
Angel
