This package enables you to transform your app.config or any other XML file based on the build configuration. It also adds additional tooling to help you create XML transforms.. Written by: Sayed Ibrahim Hashimi, Chuck England and Bill Hiebert
I spent an afternoon trying to get this going for a team project. After a fair while thrashing with the already-mentioned "The SlowCheetah.Xdt.TransformXml" task could not be loaded from the assembly" problem, I eventually solved it by deleting the %localappdata%\Microsoft\MsBuild\Slowcheetah folder and it semed to resolve itself on my local machine and I was allowed to build and run stuff. I then deployed this to my colleagues who didn't have the plugin, under the impression that the NuGet package would make everything alright. No joy, regardless of what I tried. I'm now having to see if I can hand-roll a solution for changing config settings for people. Gets 2 stars because I like the idea and it kind of worked on my machine.
facing error - Error 1 The "SlowCheetah.Xdt.TransformXml" task could not be loaded from the assembly C:\Users\SESA254846\AppData\Local\Microsoft\MSBuild\SlowCheetah\v2.5.10\SlowCheetah.Xdt.dll. Could not load file or assembly 'file:///C:\Users\SESA254846\AppData\Local\Microsoft\MSBuild\SlowCheetah\v2.5.10\SlowCheetah.Xdt.dll' or one of its dependencies. The system cannot find the file specified. Confirm that the <UsingTask> declaration is correct, that the assembly and all its dependencies are available, and that the task contains a public class that implements Microsoft.Build.Framework.ITask.

Excellent work -- so far only one major problem with web applications (solved here: http://stackoverflow.com/questions/16225304/using-slowcheetah-config-transforms-on-web-config-in-a-3-5-web-forms-app)
It works in vsnet 2012, but NOT on the TFS build server. I did not installed the plugin on the built server I expected that the plugin was required only in the configuration phase, not to trigger the magic , that is that it used the native xmltrasform features .. isn0t it the case ?
Hi e.sabbadin, when you install SlowCheetah into a project there is a message in the package manager console regarding build server support. Because of the way NuGet package restore is implemented there is some additional steps that need to be taken. You can read more info on how to enable that at http://sedodream.com/2012/12/24/SlowCheetahBuildServerSupportUpdated.aspx.
It really annoys me that after an upgrade Slow Cheetah suddenly stopped working. In the first instance I was really pleased with this tool, but I can not use it when it is this buggy. It is a shame that there are no other tools doing the transformations, as far as I know.
Release 188.8.131.52 simply sucks. It cannot even build project by throwing error - Could not copy the file"...exe.config" because it was not found.
PS: I wonder why there is no way to download earlier versions. It would at least made it easy to downgrade. With corporate firewall blocking NuGet packages, I am left with no options but to uninstall SlowCheetah and wait for next release that will fix the issue. So bad!
Sorry I had some issues with 184.108.40.206. Things should be better with 2.5.8, can you try and let me know? FYI regarding installing older versions you can always use the NuGet package manager console to install a specific version of the build support.
Nor effective transformation nor transform preview works when I use your custom extended transformation attribute described at http://sedodream.com/default,date,2010-09-09.aspx which indeed works like acharm ;).
Here is the result of the build :

Is there a way to make them work together ?
We have a shared config file across multiple projects, We use a link to the Root App.config file and another CustomConfig.config file which are used all over the place when i click on AddConfig Transforms it shows me a dialog box.
"Add as linked configs?"
Press yes then it says
"Object reference not set to an instance of an object."
Any idea on what could be happening at this point?
I was trying to add config files that were not debug or release for my other environments. I didn't see any way through VS to do this, so I decided to edit the project files. I added a PropertyGroup setting as well as an ItemGroup setting in my project file. The new config did show up under the app.config, however the actual build for my selected config did not transform the configuration or put the built files into the same named folder under bin. Suggestions? Is there a limitation to only debug and release builds? Thanks
I have build the transform replacement using the plungin on a Class Library project and it works amazingly on my box. I checked everything into SVN and everyone who got the project from SVN are unable to get the replacements to work. I have the following setup..
App.Debug.QA2.config We checked a few things.. everyone has the plung-in installed, we are all on VS2013 Pro, our project files (XMLs) are good, we are all selecting the correct environment (QA1/QA2) build configuration when we build but for everyone else the <dllname>.config file is not getting replaced. any inputs?
Via Nuget, I've installed SlowCheetah 220.127.116.11 and SlowCheetah.Tasks.Unofficial 1.0.0, and am unable to add a transform to any of my solution's projects' app.config files. When I right-click on an app.config file, I do not see "Add transform" in the context-sensitive menu that appears.
I have tried uninstalling and reinstalling SlowCheetah and SlowCheetah.Tasks.Unofficial, as well as reloading project, and restarting Visual Studio. None of these have helped.
I know that you had some issues with build servers in the past, and I've tried some of the fixes that you had suggested for those, but I'm still having a significant problem using Slow Cheetah on my build server. I am using a server running Windows Server 2008 R2 Standard. I'm using FinalBuilder and MSBuild to build my projects. Here's an overview of the problem:
In the Slow Cheetah folder (../MSBuild/SlowCheetah) there is one folder called v18.104.22.168. This folder is empty. When I commit changes to a project, during the build process two new folders are created, once called v1, and one called v2.5.10. All of the project code is copied into the v2.5.10 folder. I'm then told that the build can't find the slow cheetah.dll, and the build fails. If I go in and manually delete the two created folders (v1, v2.5.10), then run the project again (using FinalBuilder), it works and no folders are created. Any ideas on how to fix this problem? I really like this product, and it makes it much easier to work on projects; I'm just having a problem when building. Thanks in advance!
I've had plenty of the same issues myself.
Tried following instructions at http://sedodream.com/2012/12/24/SlowCheetahBuildServerSupportUpdated.aspx
to no avail...
One of my solutions IIRC was to check in the SlowCheetah packages files into source control alongside my solution, then manually editing the project-level .targets files to point at this, rather than AppData. Not ideal at all, however, as SlowCheetah updates will blow this away; rare but would be annoying to say the least.
So I tried something else: logged into the Build Server (thank goodness I have permissions) and copied the folder from my local machine (C:\Users\<me>\AppData\Local\Microsoft\MSBuild\SlowCheetah)
to the corresponding folder on the build machine, under the build user's account. Again, glad and lucky I have sufficient privileges... not really an enterprise-level scenario, especially if you have multiple/many build servers; or an environment where you don't have access to the build server.
A better solution I've considered is to write an MSBuild script, perhaps EnableSlowCheetahForTeamBuild.proj, that copies the SlowCheetah files from the downloaded workspace to the appropriate folder on the build server each time. Does require the SlowCheetah package stored in source control, but worth it given all the issues we've had. As it would run under the build user's account, it would likely have the sufficient permissions, and it would scale out seamlessly to a 1+ build machine scenario. I'll probably set this up at some point.
Frankly, given the number of downloads, I'm surprised more people aren't complaining - I'd love to hear from someone who has had luck with Sayed's 12/2012 solution, because nobody here has been able to get that working.
I opened VS2010 under Windows XP, installed the latest version using the extension manager in VS2010. Then created a new Project and added a transformation for an appsetting. The "Preview Transform" is working and displaying the replaced data, but when I run the simple console application, it does not transform the app.config.
Is the transformation not working under WinXP?
