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've been coding large financial trading frameworks in VS/C# since .NET 1.1 days (12/13 years). From this perspective, I can affirmatively state that Slow Cheetah is by far the most productive package that is not currently integrated into the VS tool. I'm walking through a major rollout now involving five different staging environments and over twenty different server configs. Without Slow Cheetah, the other 35 people in the deployment team waiting on my builds would be left high and dry while I tried to manage the configs by hand. VS management - what the *hell* are you thinking? Integrate!
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".
I am trying to run msbuild on Hudson build server. The builds fail with following error -
D:\Hudson\jobs\MyProj\ASSEMBLIES\SlowCheetah\SlowCheetah.Transforms.targets(101,5): error : Name cannot begin with the '<' character, hexadecimal value 0x3C. Line 23, position 1. [D:\Hudson\jobs\MyProj\MyProj.csproj]
The same project however builds from Visual Studio. Any idea what might be wrong here?
Slow Cheetah has worked perfectly for over a month. Now, all of the sudden, my builds are not transforming. I do have the configuration setup on multiple projects within the solution. Both projects have the associated Debug & Release configuration files associated with the parent app.config file.
Here is an example of my transformation statement.
<add name="MSSQL" connectionString="ConnectionStringHere" xdt:Transform="Replace" xdt:Locator="Match(name)"/>
After building in either Debug or Release, I am checking the (ApplicationName).exe.config file. Here, the values do not change. I have even selected the "Preview Transformation" and the preview works without failure. It seems like Slow Cheetah is not getting the call during build.
I have uninstalled and re installed the Slow Cheetah extension. No luck.
Any recommendations on how to fix this problem?
I am able to create an entirely new project and the transforms work fine. It would appear something became corrupt or missing altogether. It seems odd that both projects would do this simultaneously.
I'm trying to use SlowCheetah on an .edmx file to change an attribute of the Schema element from ProviderManifestToken="2008" to ProviderManifestToken="2005".
But, before I can get even that far I created the most minimal transformation file which only includes the root element. Previewing the transform should result in no changes, but what happens is that the final section of the transformed EDMX files has been changed. It incorrectly changes the <Designer> element to <edmx:Designer>.
Here's the transform file I'm starting with:
<?xml version="1.0" encoding="utf-8" ?>
<!-- For more information on using transformations
see the web.config examples at http://go.microsoft.com/fwlink/?LinkId=214134. -->
<edmx:Edmx Version="3.0" xmlns:edmx="http://schemas.microsoft.com/ado/2009/11/edmx">
I imagine this problem could be reproduced with any edmx file.
I have installed SlowCheetah - XML Transforms and installed SlowCheetah using the Nuget Package Manager. I am using Visual Studio Professional 2012 Update 2.
I have an .net console application where SlowCheetah is working successfully for me. I created a Release build of my .net console application and placed it in a different directory.
When I use Visual Studio 2012 to access this copy of the .net console application SlowCheetah does not show as an installed package. I then attempted to install SlowCHeetah using the Nuget Package Manager. A window appears with messages about the install progressing. The window closes and the package does not show under the installed packages in Nuget Pacakage manager. Because the installation fails the transforms are not working.
Is there an installation log file that I can read to see if any errors happened during installation.
I have just installed slow cheetah. I have other config files such as connectionStrings.config in my web project. When I build they are getting transformed and updating the config files in my application route.. The default behavior is for them to only transform on publish?
I've been using this tool for windows apps and it works perfect..
What I was expecting though - that after I add it to the WEB-MVC project and hit "F5" (as the picture above says - the transform would be applied.
How do I make this work for WEB projects ?
I'm running VS2012. After I add the transforms to either web.config or app.config, the only way to see the new transform templates is to "Show All Files" in solution Explorer. Why can't I expand the the .config files without showing all files? Am I missing a setting in VS2012 or ???
I have WebApp I have been using SC on successfully but after the 2.5.5 update the publish fails. I get "Could not write Destination file: access to the path******** denied. The path is my connection.config file which as the transforms. I remove the transforms and the build succeeds. Is the 2.5.1 or 2.5.2 build available for download to see if the issue goes away? I am using VS 2010
I've heard of this issue but have been unable to reproduce it. For a project which has this issue could you try the following. In the packages folder there is a SlowCheetah folder. Under that you will find a tools folder. Can you replace the SlowCheetah.Transforms.targets with the file at https://raw.github.com/sayedihashimi/slow-cheetah/1f90325f2d1a72f221fe116289c1a8c14c43ccfa/SlowCheetah/Resources/Install/SlowCheetah.Transforms.targets. After that close and re-open VS and see if the issue continues or not. If that fixes it I may ask you for some build logs to see what the difference is here.
This seems to have worked. I had to place the targets file under MSbuilds as I didn't have packages folder. It did successfully build the solution and the transforms look correct. I noticed a change of reference between the two targets files.
This file: https://raw.github.com/sayedihashimi/slow-cheetah/1f90325f2d1a72f221fe116289c1a8c14c43ccfa/SlowCheetah/Resources/Install/SlowCheetah.Transforms.targets
It's not available. I'm getting a 404 error on that site.
Has this been solved yet? I'm having the exact same problem. I have just setup xml transformation and on my first build on the build server I'm getting this access error.
I'm using VS12 Update2. Changing that .targets file manually is not a solution for us because we are using package restore on the server. I don't want to check-in that slowcheetah package.
System: VS2010 Ultimate SP1, TFS 2010 (also build server), SlowCheetah 2.5.5
On a brand new project, I added SlowCheetah 2.5.5 via NuGet to my web project. As many others have stated, it did not build correctly when run on my MSbuild server. It would continually error out with "... SlowCheetah.Transforms.Could not write Destination file: access to the path '(fullpath)\Application.Config' is denied." Since I did not have a previous version also installed, I could not use the previously suggested .targets file since that requires the SlowCheetah.Tasks.dll library.
Through the NuGet package manager, I removed v2.5.5 from my project and added SlowCheetah.Tasks.Unofficial instead. After checking in all of the solution/project changes associated with switching versions and running a new build, the project built successfully.
TL;DR: If you're using SlowCheetah 2.5.5 and getting the 'Destination file access denied' error, try switching to SlowCheetah.Tasks.Unofficial available in NuGet.
After further testing, using SlowCheetah.Tasks.Unofficial was not correctly transforming files upon running MSBuild. I reverted back to SlowCheetah 18.104.22.168 (via the package manager console), modified my build per http://sedodream.com/2012/12/24/SlowCheetahBuildServerSupportUpdated.aspx and everything is happy again - transforms work perfectly.
I'm still not able to reproduce this. I looked a log files from two different machines in which one works and the other doesn't and still was not able to see what the issue was. I was thinking that the issue was isolated to Visual Studio.
This is the first that I'm hearing of this from a build server.
Martin, could you help me out here? If you could that would be awesome. Could you produce a build log of a 2.5.5 project failing and then convert to 2.5.3 and succeeding?
My email is email@example.com.

Could this error be related as to whether or not you have 4.0 or 4.5 installed?
I see this error on machines configured like mine using VS2010 Pro except that .NET 4.5 is installed on my and isn't installed on their machines (they have .NET 4.0 though)
I think there might be an issue with .NET 4.5 not installed that is causing this.
I did a clean install of VS2010, SP1, MVC 3, MVC4 and .NET 4.0. The build wasn't working correctly with the MSBuild task for Slow Cheetah 2.5.5. I then installed .NET 4.5 and the build started working fine with my setup and the MSBuild task for Slow Cheetah 2.5.5
Please look into this if at all possible
I can confirm that this is an issue with .NET 4.5. I'm using VS2012 Professional with TFS 2010 as a build server. I checked in the SlowCheetah package and my build server got ""Could not write Destination file...." error. After installing .NET 4.5 on the build server the build is now working.
