Doctor Deploys Blog

Do you own the deployment of your product and require the .NET Framework to be installed before you can install your application? If so, I want to hear from you.

I have a few general questions but any comments are welcome as long as they are constructive and actionable. My goal is to use this data to do what I can to improve the .NET Framework Redist experience in future versions.

Do you have a bootstrapper/chainer that preinstalls .NET? If so, which one (VSI, InstallShield, Wise, ClickOnce, custom)?
Do you block and point your user to the location to download and install .NET?
How large is your application?
How is your product deployed (Web download, CD, DVD, USB)?
What do you think about the size of the .NET package?
Do you know about the small package for .NET 3.5 that will download only what your user need? If so, do you use it?
What do you like about the .NET Framework Redist?
What do you dislike about the .NET Framework Redist?
Do you have any specific problems you can tell me about that you have had in deploying the .NET Framework?

Like I said, the info above will be helpful to me but I dont want to limit responses to these questions. We have a lot of data about the various issues people encounter while installing the .NET Framework but we dont have as much data about the ways people are deploying it and using it as part of their deployment. This is the type of info I’m looking to gather.

You can post as a comment or email me the info if you dont want it posted and seen by all.

Many times people want to take advantage of the Wix v3 patch building features but didnt build their original product using Wix. for example, they may have used Install Shield, WiX v2 or one of the other tools out there. I ran into this when I needed to create a patch for a product we shipped from Visual Studio before the Visual Studio build moved to WiX v3.

 WiX v3 has a feature I added a while back to support this scenario. It allows you to point at an admin image of your msi based install package. This will be very familiar to some of you who have used patchwiz and pcp’s in the past. The difference here is that your patch authoring can be done using the WiX v3 Patch element and it follows the same workflow as patching a WiX v3 based msi after the first stage of creating the diffs.

Something I found really easy, and I could see this being used by smaller products who dont have a lot of infrastructure, is the ability to hand edit your admin image to product the patch. For example, I wanted to update a single file in my product:

1. I created an admin image
2. I made a copy of the admin image
3. I updated the loose file in my copy of the admin image

After running it through the series of command lines, I got a patch that updated the file. Pretty simple…

The command lines you need to run are all the same as the ones in my sample: Building a Patch using the new Patch Building System - Part 3. The only difference is that you need to pass the -ax command with a path to extract embedded binaries to instead of the -xi switch. This tells torch that the input is admin image instead of xml. Also, specify the path to the msi in the admin images instead of the wixpdb as the target and upgrade. Everything after that should follow the same process.

Let me know how it works!

Bonus feature: One of the most useful things in the WiX v3 patching system is the ability to filter whats in your patch using patch families to only ship your customers the updates they need. This allows you to grab changes per Fragment from your wix source. When patching from admin images, there is no source so you would think that the filtering isn’t suppoted. Not so! This was one of the more fun parts of this implementation. We “auto-fragment” the msi into what we consider to be the optimal chunks to give you the ability to filter if you choose to do so.

I should have made this post about 6 months ago as I was implementing the WixPdb feature in WiX but better late than never :).  The wixpdb was conceived as a solution for a limitation in the original patch building system. Originally, WiX v3 patching only supported creating transforms between two wixout files. This was flawed in that many things modify the output after the wixout is generated by light which weren’t being reflected in patches. I knew I needed the patch build system to be able to create transforms from something closer to the final output. Thats what the WixPdb is. It is all the data in the output right before creating the final msi. With that data, we can now create more accurate transforms to what people expect when diffing two products. I updated my blog with samples on how to build patches to show that I now recommend using the wixpdb instead of the wixout.

Down the road, I look forward to seeing what other features we can get out of the wixpdb. It provides a ton of information an allows you to potentially connect install time errors all the way back to the wix source and line number. Static analysis is another benefit. I updated smoke to be able to take the wixpdb so it will give you source and line number information for ICE errors. Statis analysis on the wixpdb itself may also be interesting because it contains more data than in the msi. It is the one place where the wix source data and the msi data connect. Let me know if you have any ideas of how to use the wixpdb in some cool ways…

I’ve been meaning to post about this for a while but just never got around to it. A few months ago I extended the implementation in WiX to allow foreach loops using any variable over any given set of values. Previously it was limited to only those variables that were defined in your preprocessor extension.

While this example wont do much for you, it demonstrates what a foreach loop will do. <?foreach?> loops can simplify authoring in many ways, especially for complex products.

Example:

<?foreach number in 1;2;3 ?>
    <Property Id=”Property$(var.number)” Value=”value$(var.number) />
<?endforeach ?>

Will result in the following being passed to the compiler:

    <Property Id=”Property1″ Value=”value1 />
    <Property Id=”Property2″ Value=”value2 />
    <Property Id=”Property3″ Value=”value3 />

I want to note as a caveat, It can be very easy to break component rules by changing the contents of a component by simply changing the values you iterate over. I recommend not using foreach loops anywhere near components unless you have really thought it through.  Also, while using the preprocessor can be very handy for minimizing the amount of wix code you need to maintain, it can really confuse some of the tools that are out there that help you generate or maintain your wix source. In general, think about other options before you use the preprocessor as a solution but if you think its your best option, enjoy

This post is a follow-up to Rob Mensching’s "Visual Studio ships the WiX toolset" blog entry.

One of the key tenets WiX development is operating under is to make all changes available to both community WiX as well as "Rosario" WiX. (They actually get fixed for the community first :))

Each time we make a major "Rosario" WiX release, I plan to list the major differences between community WiX and "Rosario" WiX.

Differences:

Signing - The WiX binaries shipped with Visual Studio will be signed with a Microsoft signature rather than the community WiX signature.
Contents of the installer - In order to limit our test surface and ship the mainline tools in the highest possible quality, there are a few tools that will not be shipping in the VS package. Another option we are exploring is to supply some sort of SDK for the tools we don’t plan to provide mainline support for.
Supported VS versions - The "Rosario" WiX toolset will only install on VS 2008 while the community version will continue to install on both VS 2005 and VS 2008.
Nant - No support for Nant will ship in the "Rosario" box.
