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 really like this tool for Visual Studio (both 2010 and 2013), and cannot understand Microsoft's reluctance to adopt this as a standard feature for all future versions of the IDE.
I found that for me, using the VSIXinstaller for each edition of Visual Studio I'm using, worked well to get it installed. And I have to make sure that custom XML-styled configuration files are marked with "Copy always" or "Copy if newer".
The simple mechanisms for replacing parts of XML that are used by msdeploy on web.config are equally useful with any other config files. SlowCheetah does a great job of extending that functionality in a transparent way to other files.
This extension has saved my countless hours setting up automated builds and continuous deployments. This is a must have if you need to do configuration file transforms during your build and deployment process.
Terrific work -- the only problem with web.config can be solved with a little trickery (http://stackoverflow.com/questions/16225304/using-slowcheetah-config-transforms-on-web-config-in-a-3-5-web-forms-app).
Very useful. I like that it looks at the Publish Profiles, although be cautious when you rename a Profile, it does not rename the previously generated transform files. But you can always regenerate and delete the old.
Simply does not work with ClickOnce. I have not found any information that shows how to make XML transformations work with ClickOnce. You can run the transform preview and it looks correct, but the .config.deploy file generated by ClickOnce is the original, untransformed config file. Very frustrating and completely unusable in my situation.
Really like SlowCheetah, but there is one scenario which I couldn't get working out of the box.
I have a web.config with the following transforms/configurations:
When I publish for Dev, only the Dev transform gets applied and put into the web.config.
This is the standard behavior.
What I actually want to do is build/publish once and deploy on any of the machines.
After publish I want the resulting web.configs to look like this:
Web.Dev.Config (transformed web.config for Dev)
Web.Test.Config (transformed web.config for Test)
Web.Acc.Config (transformed web.config for Acc)
Web.Prd.Config (transformed web.config for Prd)
Is this possible out of the box? Or do I need to change my build scripts manually?
I just downloaded the project from github and I'm trying to get it to compile. I've installed Visual Studio SDK and the NuGet packages but I get an error on the reference Microsoft.VisualStudio.ComponentModelHost (version 10.0.0.0). I guess it's because I use VS2012 (and thus VS2012 SDK, version 126.96.36.199). Are you still using VS2010? Is there a way around it so I can still use VS2012 or do I need to go back to VS2010?
I've been using SlowCheetah for quite some time so I suppose I should help out with the development ;)
Finally got it to work. Had to do the following:
Install VS2010 SDK
Install VS2010 SP1
Install VS2010 SDK SP1
Install VS2012 Update 4
Install VS2012 SDK
Open the solution and download the missing Nuget packages.
And you're all set!
The Jenkins service is running under the Local System account. Can it be that Automatic Package Restore is not correctly installing the SlowCheetah files in the AppData folder? The build is looking for them there, but can't find them:

I've installed the version 2.5.10 and it doesn't work anymore. Please fix or let me download the 22.214.171.124 version.
Error 9 The "SlowCheetah.Xdt.TransformXml" task was not found. Check the following: 1.) The name of the task in the project file is the same as the name of the task class. 2.)

Just some extra info... I found the following folder (it's a x64 system):
But it has no content inside :-(
I have a Web.Debug.config file that logs to a debug log file instead of the release version. In VS 2010, after I upgraded to the extension version 2.5.10, it would no longer transform web.config in debug mode. After I installed the NuGet SlowCheetah package 2.5.5, then would it start working again (installing the latest SlowCheetah NuGet did not work).
After upgrading to VS 2013, even with using SlowCheetah NuGet 2.5.5, it's no longer transforming web.config in debug mode. I also tried NuGet package 126.96.36.199 and it still doesn't work. The Preview Transform function shows the correct transform being applied.
Any help would be greatly appreciated.
We are encountering the following error on many computer, we just downloaded the latest version, and we are trying it on VS2013:
The "SlowCheetah.Xdt.TransformXml" task could not be loaded from the assembly C:\Users\Ahmad\AppData\Local\Microsoft\MSBuild\SlowCheetah\v2.5.10\SlowCheetah.Xdt.dll.

We tried to search the path, there is two folders:
C:\Users\Ahmad\AppData\Local\Microsoft\MSBuild\SlowCheetah\v188.8.131.52; this contains the vs extension,
C:\Users\Ahmad\AppData\Local\Microsoft\MSBuild\SlowCheetah\v2.5.10; this contains a copy of my project !!! what is that?
I'm getting the following error message when trying to use SlowCheetah 2.5.10:

This problem was not happening when using version 2.5.5, and it started happening after updating to this version.
Are you using Ncrunch?
If you are you must include the slowcheetah package in Ncrunch.
You didn't have to do this in verison 2.5.5
I'm not using Ncrunch yet, I'm just using NUnit framework. What I did was to install the SlowCheetah package from Visual Studio Gallery, add transforms in the configuration file and compile the solution.
I'm currently using VS Ultimate 2012 with .Net fwk 4.5
I'm new to SlowCheetah and was wondering if someone could provide a simple example for me. I've setup a simple C# app, and I added one setting to the settings called ServerName. In the App.Config file I see:
<setting name="ServerName" serializeAs="String">
I've right clicked on App.config and created the transform files and I see them. I'm having trouble with the syntax of the transform. I've tried several variations, but I think:
<add key="ServerName" value="DevServer" xdt:Transform="Replace" xdt:Locator="Match(key)"/>
<add name="ServerName" xdt:Transform="Replace" xdt:Locator="Match(name)">
Should be correct but it's not working. What am I missing?
Thanks in advance for your help!
Okay, I figured it out:
<setting name="ServerName" serializeAs="String" xdt:Transform="Replace">
works. Is this the best way?
My example above is missing an xdt:Locator and will drive you nuts. here's some example transforms which are working for me:
<!-- We don't want to change the Flow Through setting so nothing special has to be done -->
<!-- To Delete a setting, use the Transform Remove -->
<setting name="DeleteThisSetting" xdt:Transform="Remove" xdt:Locator="Match(name)"/>
<!-- To Change a Setting, use the Transform Replace -->
<setting name="ATweakedSetting" serializeAs="String" xdt:Transform="Replace" xdt:Locator="Match(name)">
<value>This Setting was tweaked in app.debug.config</value>
<!-- To Add a Setting, Use Transform Insert-->
<setting name="AnotherAddedSetting" serializeAs="String" xdt:Transform="Insert">
<value>This Setting was added in app.debug.config.</value>
<!-- if you want to get REAL picky on where it goces, use Insert After -->
<!-- The xpath expression does the heavy lifting -->
<setting name="AnotherAddedSettingPlacedAfterServerName" serializeAs="String"
<value>This Setting was added in app.debug.config.</value>
Basically I'm trying to integrate into build process on TFS and I'm following instructions from a blog post you had. It is not showing the extra project that you are mentioning in the post.
Please see question on StackOverflow.
