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 126.96.36.199 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 188.8.131.52. 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.
Can SlowCheetah transform app.config for WCF projects when published using the file publish method.
I currently have Version 2.5.10 installed and it does not appear to be transforming an publish for my WCF project.
We have multiple target environments (DEV/QA, etc.). Since the only things that change are configuration settings (nothing done with precompilation statements) we'd rather not have to have a configuration per environment; seems like a waste to recompile for each environment since the code is the same. We'd also like to minimize the customization of the SlowCheetah.Transforms.targets file. Is there a recommended way to compile the code once and get SlowCheetah to create transformed config files for multiple environments?
Thanks in advance
No, I haven't. I was hoping to get a reply from Sayed but never did. I know I could do it by customizing the targets file to use a custom variable like $(Environment) instead of $(Configuration) but I was hoping to not customize anything so that I wouldn't have to revisit the targets file to check for possible conflicts.
Overall, I do like SlowCheetah I just really dislike how it and XML Transforms overall are married to build configurations. The binaries for us are not different per environment. The only thing that is different is just the configs. We currently use XML Preprocess and so far, I'm thinking we're going to stick to it.
This is exactly the problem I'm experiencing. I'm trying to overcome the problem by only referencing the SlowCheetah target, but that doesn't work:
MSBuild [path to project file] /t:TransformAllFiles /p:Configuration=Release
I found a pretty decent work around for this, while still using SlowCheetah.
I created some afterbuild events:
<TransformXml Source="web.config" Transform="Web.Staging.config" Destination="webstaging.config" />
<TransformXml Source="web.config" Transform="Web.Release.config" Destination="Webrelease.config" />
With the devops tool we are using (Buildmaster) The files are renamed and replaced on the correct environments.
It's not ideal, but you still have central config files (web.config and umbracoSettings.config), and you only have to manage the changes in the XMLtransform files.
I deploy my cloud services solution with Visual Studio 2013 (Azure SDK 2.2 + SlowCheetah). I created new build configuration 'config_name' besides standard Debug and Release and I use it in my publish profile. But when I start deployment I see SlowCheetah (I guess) uses Release config:
Transformed Web.config using C:\...\Web.Release.config into obj\Release\TransformWebConfig\transformed\Web.config.
ok, this is really important - I have staging deployment and production version of my cloud app. When I deploy staging it's important to have a connection string point to STAGING db and have all other things configured differently (Twilio, sendgrid, etc). Now I can't have it bacause my Debug config is for local development, Release is for Production, and the one that doesn't work is for Staging. So I basically have a hard time deploying and testing my solution.
ok, solved this myself. I opened configuration manager and under build everything were selected as Release. Changed this to 'config_name' and it worked (well, i had to do this in csproj and sln files manually, but that's another story).
I'm using VS 2012 and Azure Tools 2.1 with SlowCheetah. I downloaded & installed the VS extension and everything seemed to go fine: I was able to create Debug and Release versions of the app.config for my worker role. I added transforms and checked them with "Preview Transform". All good. But when I build -- nothing. Transforms haven't been done. Am I missing something? Is there somewhere I can look to see if the transform failed or get some logging data on what's happening?
I'm looking for a way to use msbuild together with slowcheetah to produce/publish *only* the transformed files.
MSBuild [path to project file] /t:TransformAllFiles /p:Configurat
That doesn't give any errors, but it doesn;t give me my files either.
I think because SlowCheetah only transforms on publish.
I tried some other options as well, but to no avail.
I'm receiving the error:
Could not copy the file "bin\Debug\TIPS.Client.exe.config" because it was not found.
I'm not alone
If I simply create a new WPF application and enable "Enable ClickOnce security settings" I get the error.
I've created an app that illustrates the problem
VS 2012 update 3
installed VS slowcheetah expansion
create wpf 4.5
enable ClickOnce security
I'm having the same Problem with Version 184.108.40.206, VS2013 Update 3 in an WPF-Application. Added the transform, did some transformations, preview is working fine, but building the release gives me the error described here. Click Once Security is enabled.
Ok sorry, If I choose Tools/Extensions and Updates it tells me I have 220.127.116.11 installed. As building is not working I uninstalled the package from my project and recognized I had 2.5.7 there. So I uninstalled it (which didn't work right away) and installed it (why 2.5.8?) again. Now its building!
Sorry switching to .NET 4.0 caused the extension to not work in VS2010. I've just released 18.104.22.168 which is built with .NET 4.0 and should work with VS2010. Please try it out and let me know if it does not work.
i am using VS 2012 with update 3. After installing the latest from Nuget i was fully expect to see the context menu "Add Transform" when right click on a app.config file. but no such menu comes up. how do i get it to work? any documentation/user guild on this?
Sayed, my two apps have too many dependencies and hooks into the larger solution to offer as a repro case. So I went and created a new WinForms app and cannot cause the problem, even with exactly the same config files and transforms. I'm not sure what to make of this. Clearly something is wrong in the two projects I have. If it helps any I am willing to offer you the project file itself, though it won't build of course due to the lack of dependencies.
Sorry for the confusion guys. The NuGet package is just a mechanism to ship the underlying build support. The Visual Studio extension (which this is the download page for) ships the menu options in Visual Studio.
It is authored this way so that when working in teams if one person adds SlowCheetah everyone will get the correct build behavior without having to install the extension. Only those interested in creating new transforms need to install the extension.
Unless you are an advanced user you can view the NuGet package as an implementation detail.
I hope that clears things up.
I am using VS2012.3 and installed the VS extension to a web site project in hopes of transforming a CMS specific file AssetManagement.config, but I do not see the context menu offering the "Add Transform" option. I tried to install the Nuget package but installation failed with the message "Project file not found". Does this work only with WAPs?
I am using VS2010, I've installed the vsix using Tools > Extension Manager. I've created a new Console Application with App.config file, I don't see an "Add Transform" option. Doing the same with VS2012, I do get the "Add Transform" option - is there a version available for VS2010?
Sorry guys switching to .NET 4.0 caused the extension to not work in VS2010. I've just released 22.214.171.124 which is built with .NET 4.0 and should work with VS2010. Please try it out and let me know if it does not work.
Haven't tested it much yet but:
1) Download 7-Zip
2) Download the VSIX from the link above
3) Right click on the VSIX and select Open with -> Choose default program
4) Select C:\Program Files\7-Zip\7zFM.exe (or Program Files (x86) for 32 bit)
*** Make sure to uncheck the box to associate 7zFM.exe with VSIX files ***
5) Right click on extension.vsixmanifest and select Edit (F4)
6) Copy/paste the <VisualStudio Version="11.0"> node and replace 11.0 with 12.0
7) Save and close Notepad - 7-Zip will ask you to save the file back in the archive
8) Hope it works ;)
I was able to do transforms but haven't tried to build or deploy anything yet using VS2013
Worked like a charm. Thank you very much!
I did deploy with no problems.
I used the excellent Total commander to open the vsix file, select any file in right pane and use Ctrl-left arrow to open it in the right pane. Brilliant :)
I'm sure there's a way to do this if I buckle down and determine how this works, but my object is to do the transform without making the App.Debug.config (or other XSLT) part of the project, otherwise it will remain permanently checked out by all developers and in their TFS exclude list. Right now it doesn't work unless it is part of the project.
We do this for web services. We have a Web.Debug.config.template file checked into the project, which each developer can copy to make their own Web.Debug.config file which is not checked in and not part of the project. Then using the technique I found on http://stackoverflow.com/questions/2932059/managing-web-config-for-teams-in-vs2010-tfs
we create a Web.Base.config file which no one checks out unless necessary it creates a Web.config file on each build.
This should be easier with App.Config since it isn't modified, and is transformed to the bin directory.
Question: Has anyone done this with SlowCheetah transforms and is willing to share the technique? I assume it is possible with a custom targets file and modification of the csproj file, but unfortunately package restoration might wipe out the modifications.
