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.

by Gustin G | September 02 2014

Excellent tool - I use it in every project to achieve a clear configuration scenario.

by Thomas TwoAngel Rud Rasmussen | August 20 2014

Doesnt transforms, doesnt add new transforms, doesnt transform web.config as stated.

Soo, that's a no go im my environment

by Toons33 | July 21 2014

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).

THANK YOU SlowCheetah team.

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.

Works like a breeze. :)

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.

by Henrick P | June 19 2014

A real must if you wish to deploy to different machine with different configuration settings stored inside some other [filename].config. Still wonder why Microsoft don't have this functionality out of the box.

Great!

by Brad Deem | May 08 2014

Excellent! Glad to see this come to projects other than web. Now if only Microsoft would pick it up out the box...

Just remember to verify that it works without SlowCheetah installed so other devs don't have issues. Here's what I've used before.

<PropertyGroup Label="SlowCheetah">
<SlowCheetah_EnableImportFromNuGet Condition=" '$(SC_EnableImportFromNuGet)'=='' ">true</SlowCheetah_EnableImportFromNuGet>
<SlowCheetah_NuGetImportPath Condition=" '$(SlowCheetah_NuGetImportPath)'=='' ">$([System.IO.Path]::GetFullPath( $(MSBuildProjectDirectory)\..\packages\SlowCheetah.2.5.8\tools\SlowCheetah.Transforms.targets ))</SlowCheetah_NuGetImportPath>
<SlowCheetahTargets Condition=" '$(SlowCheetah_EnableImportFromNuGet)'=='true' and Exists('$(SlowCheetah_NuGetImportPath)') ">$(SlowCheetah_NuGetImportPath)</SlowCheetahTargets>
</PropertyGroup>
<Import Project="$(SlowCheetahTargets)" Condition="Exists('$(SlowCheetahTargets)')" Label="SlowCheetah" />

Conflicts with ReSharper 8.1. Had to Suspend and Resume Resharper because I could not edit any file after applying a template

by Craig Brett (JP) | March 25 2014

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.

Nice integration with VS. Makes a chore much more manageable.

by Spesimensen | January 30 2014

Excelent tool! Thank you very much.

  • PropertyGroup location in the project file might break the transformation !!
    2 Posts | Last post September 19, 2014
    • After hours of debugging trying to understand why SlowCheetah stopped working after updating to the last Nuget package I discovered that if the "SlowCheetah" PropertyGroup is at the end of the csproj file, file transformation stops working.
      If I move it to the top, it works.
      
      It stopped working because when I updated the Nuget package, the PropertyGroup has been removed from the csproj file and added back, but at the end.
      
      After more research, it seems that the "SlowCheetah" PropertyGroup must be before the following import (the reason being obvious when you know it ^^) :
      <Import Project="$(SlowCheetahTargets)" Condition="Exists('$(SlowCheetahTargets)')" Label="SlowCheetah" />
      
      Could you do something about that ?
      It's a quite hard issue to identify and a simple package update might break SlowCheetah...
    • Thank you julienN!!! You saved my day. At first I thought that the problem is in the build server, but no, actually it's the problem inside Slow Cheetah. I think it should be fixed ASAP, it's too dangerous to use such tool in production...
  • Rename transformation file
    1 Posts | Last post September 02, 2014
    • Hi,
      I added a transformation file  from right click context menu of my Connections.config file subsequent to previous additions done a few months ago.
      The file added is labeled 'Connections.Profile1.config'.  Right click on the file, but there is no option to rename the file. How do I rename the file to Connections.QA2.config.
      Thanks,
  • Transformed files from class library project not copied to the referenced projects
    2 Posts | Last post August 08, 2014
    • Scenario:
      
      I have a class library project with custom .config files. Build Action for these config files are set to 'Content' and 'Copy Always'. This library project is then referenced in at least 4-5 console applications within the same solution. When the solution is built the class library's assembly and the custom config files are copied on to the the referenced projects bin folder.
      
      What I am trying to do:
      
      Use SlowCheetah to transform custom config files
      
      Problem:
      
      Though SlowCheetah transforms the config files within the class library project it doesn't copy the transformed file into the referenced projects. i.e it always copies the source/original file.
      
      Found couple of other threads but none of them were solutions based on SlowCheetah, any suggestions would be helpful. Note that I am using Install Shield Limited Edition, so the solution needs to work for .msi/setup files. Also, I dont want to link files and apply transform on the linked files as then I would have to do the same transform on all referenced projects.
      
      Thanks
    • Given ClassLibararyA references ClassLibraryB:
      
      * Ensure configs from both class libraries are named App.config
      * Configure transformations for both App.configs using SlowCheetah (even if you only care about one)
      * Build
      
      In the output folder for ClassLibraryA, you will find ClassLibraryB.dll.config (the transformed App.config of ClassLibraryB).
  • xdt:Locator example
    2 Posts | Last post July 01, 2014
    • Hi Sayed,
      
      I'm using slow cheetah to manage a custom XML file.  The elements that I want to update/replace don't have an attribute assigned for me to be able to use the xdt:Locator="Match(Attribute)" type of syntax.  
      
      Can you point me to an example/sample of xdt:Locator that does not use the Match syntax?  I've tried using Xpath statements but not having any luck - maybe I'm doing something wrong?
    • Clarification to my question above, if my XML file is formatted as below:
      
      <?xml version="1.0" encoding="utf-8" ?>
      <Configuration xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform" xmlns="http://tempuri.org/Configuration.xsd">
      
      
      
        <!--Sample Service1
        *************************************************************-->
        <ConfigSection Service="Service1">
          <ConfigPoint>

          </ConfigPoint>
          <ConfigPoint>
            <ConfigName>OutputFilePath</ConfigName>
            <ConfigValue>HardCodedValue</ConfigValue>
          </ConfigPoint>
        </ConfigSection>
      
      
      
        <!--Sample Service2

        <ConfigSection Service="Service2">
          <ConfigPoint>
            <ConfigName>ConnectionString</ConfigName>
            <ConfigDescription/>
            <ConfigValue>##ConnectionVariable1</ConfigValue>
          </ConfigPoint>
        </ConfigSection>
      
      
      
        <!--Sample Service3
        *************************************************************-->
        <ConfigSection Service="Service3">
          <ConfigPoint>
            <ConfigName>ConnectionString</ConfigName>
            <ConfigDescription/>
            <ConfigValue>##ConnectionVariable2</ConfigValue>
          </ConfigPoint>
          <ConfigPoint>
            <ConfigName>AuthenticationGroup</ConfigName>
            <ConfigValue>##AuthenticationVariable1</ConfigValue>
          </ConfigPoint>
        </ConfigSection>
        
      </Configuration>
      
      I would like to use Xpath locator to find all instances where ConfigValue = ##ConnectionVariable1 and replace with a new value in the transform.  I'm having difficulty with how to leverage the locator syntax to accomplish this.
      
      Thanks!
  • Failing Team Foundation build with v2.5.10.6
    3 Posts | Last post June 12, 2014
    • Hi I've been using SlowCheetah for over a year.  Awesome, thanks!
      
      However I've run into an issue I need help with please. Apologies it's not a one line question...
      
      The scenario is that in a solution which uses the "old" NuGet package restore (NuGet.exe and targets file checked into source control, no packages checked in), SlowCheetah v2.5.10.6 does not work on my Team Foundation Build server.  This is the actual error I get on the build server:
      
      C:\Builds\11\PaulSlowCheetahTest25105\Properties\SlowCheetah\SlowCheetah.Transforms.targets (153): The "TransformXml" task could not be loaded from the assembly C:\Builds\11\PaulSlowCheetahTest25105\Properties\SlowCheetah\SlowCheetah.Xdt.dll. Could not load file or assembly 'file:///C:\Builds\11\PaulSlowCheetahTest25105\Properties\SlowCheetah\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.
      
      The \Poperties\SlowCheetah dir of course just has the targets file inside.
      
      I have another solution using v2.5.10.3 with NuGet package restore and that is fine. It seems a recent change since 10.3 has introduced this issue.
      
      I searched the web and found this:
      
      https://github.com/sayedihashimi/slow-cheetah/issues/116
      
      At then end of the comments lucusc says: "What fixed it for me was to change how Nuget was restoring packages from the old way (right click solution and click Enable Nuget Package Restore) to the new preferred way. See the 2 links below for more details."
      
      However, using Automatic Package Restore poses other issues for me as my build workflow is customised from an earlier TFS version so I can't use the new TFS2013 build workflow which has Package Restore built in.
      
      Can you suggest a way forward? 
      
      
      
      
      
    • I see a few possible options at the moment:
      
      1. Stick with the "old" NuGet package restore, and install older SlowCheetah v2.5.10.3 which does work OK on my build server.
      
      2. Move to Automatic Package Restore, with latest SlowCheetah, but use this workaround to force the Package Restore to happen before the solution is built: http://blogs.msdn.com/b/dotnet/archive/2013/08/27/nuget-package-restore-with-team-foundation-build.aspx
      
      3. Move to Automatic Package Restore, with latest SlowCheetah, and modify my Team Build workflow to run the NuGet Package Restore before doing the solution build.
      
      None of these options are particularly attractive to me.  I guess 3 is the right way to go but I don't relish the idea of tinkering with the TFS build workflow.
      
      I'd be keen to hear your thoughts!!
    • FYI I went with option 3 in the end.  So updated my build workflow to do a NuGet restore before the MSBuild.  When I looked into it I found a "NuGetRestore" workflow activity so it was pretty simple to achieve.  I hope this helps somebody else!
  • Conflict with VS 2013 Git integration
    3 Posts | Last post May 29, 2014
    • The transforms work as expected for me, but they have broken the Git integration in Visual Studio so that I cannot .gitignore any of the transformations (or at least, when I do, I can't use Visual Studio's git integration). 
      
      I need *.Debug.config files to be ignored, because they have developer specific configurations that should not be committed. 
      
      This is caused by the ms-persist.xml file that SlowCheetah puts within the .git folder, which Visual Studio then uses as an override to the .gitignore file.
      
      There are various work-arounds to this issue, but ultimately, I'd like SlowCheetah to not put that file into .git at all, so that I can manage my ignores.
      
      Example: 
      new project in Visual Studio, and in a git repo.
      Transform app.config.
      Add "app.Debug.config" to .gitignore and save everything.
      Observe:
        In Visual Studios "Team Explorer" window, the app.Debug.config shows as a pending change that needs to be committed. 
        In Git command line, git status does not show app.Debug.config as a pending change.
      
      
    • Like many others here, we're seeing Slow Cheetah fail. It has been working in our web app for several months, allowing us to have different configs, one for release, one for cloud. It would be really nice to have it run on F5, but we can live with it for now.
      
      However last week it suddenly started throwing errors in our build, the MSI is still created but we're getting messages about Slow Cheetah dll not being found. In Visual Studio 2010, I can right button click and "Preview Transform" and it does show me the before and after. However it no longer works when we publish to Azure (we use VS2010 on a deployment box to do that - too small a team to have a dedicated build manager).
      
      Similarly, the regular "Release" transform no longer works on the build server.
      
      I think the time has come for Microsoft to adopt this tool, which is basically sound, and give it the support it deserves.
      
    • SlowCheetah doesn't create those files. Please file a bug with Microsoft at http://connect.microsoft.com
  • Transformations and Embedded Resource
    4 Posts | Last post May 12, 2014
    • Hi Sayed,
      
      I have an xml file as an embedded resource to be used for nhibernate configuration. I would like to embed the transformed file as the embedded resource rather than the original. Since the transformed files are copied in to the relative bin\$(Configuration) the build will and does include the non transformed file as the embedded resource. I was wondering if there is a simple way using "Slow Cheetah" to get the transformed file included as the embedded resource.
      
      One way would be to run the transforms before the build begins and add the xml file as a Link from the bin\$(Configuration) so that you always get the transformed file rather that the original.
      
      --Thanks
    • Hi Kamran, thanks for your feedback. This is not supported but you could always use the TransformXml task directly in your project files to realize such scenarios. 
    • Hello Sayed and Kamran,
      
      I am not at all familiar with msbuild tasks, but I also have the need to transform embedded .resx files and .settings files.  Do either of you have suggestions how to modify the .csproj file to accomplish this?
    • Hi guys,
      
      I also need to transform embedded resources. Could you shed some light on how to accomplish this?? Thanks!
  • Error slowcheeta.transforms.targets MSBuildLibPathLocal
    1 Posts | Last post May 12, 2014
    • Hi,
      I tried to build an asp.net project including slowsheetah 2.5.10.3 version and i got the following build error:
      
       error MSB3191: Unable to create directory "C:\Windows\system32\config\systemprofile\AppData\Local\Microsoft\MSBuild\SlowCheetah\v2.5.10.2\"
      
      Although the slowcheeta files are not located there.
      
      When i replaced the line in the slowcheeta.transforms.targets file:
      $(LocalAppData)\Microsoft\MSBuild\SlowCheetah\v2.5.10.2\
      with 
      $(MSBuildProjectDirectory)\..\packages\SlowCheetah.2.5.10.3\tools\
      
      it works!
      so, are you going to modify your that file or i miss something to be added?
      
      fyi: similar issue at: https://github.com/sayedihashimi/slow-cheetah/issues/118.
      
      Thanks!

      I would like to bring to your notice that SlowCheetah is not working with Windows azure related cloud projects.
      Is there any alternative for the same.
