Run web.config transformation from command-line - visual-studio-2010

Question

Good day!
I want to have ability to build ASP.NET MVC 2 project using VS2010 Publish dialog and from command-line.
For command-line I get the following to work:
C:\Windows\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe .\SolutionFolder\MyProject.csproj /p:Configuration=Release;DeployOnBuild=True;PackageAsSingleFile=False;outdir=c:\_OutputFolder\
The only problem I have that Web.config transformation are not applied (but added to WebDeploy package). I don't use WebDeploy. Is there any way to apply Web.config transformations?
Thanks!

Answer 1

You can also try using the XDT Transformation Tool:
http://ctt.codeplex.com was moved to Github
https://github.com/greenfinch/ctt
I'm using this instead of messing with obscure msbuild targets.

Answer 2

Here is another approach, which uses msbuild to transform Web.config file:

In my tests the results were better. Basically, you create a project file to perform only a TransformXML task:
<Project ToolsVersion="4.0" DefaultTargets="Demo" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<UsingTask TaskName="TransformXml"
AssemblyFile="$(MSBuildExtensionsPath)\Microsoft\VisualStudio\v10.0\Web\Microsoft.Web.Publishing.Tasks.dll"/>
<Target Name="Demo">
<TransformXml Source="app.config"
Transform="Transform.xml"
Destination="app.prod.config"/>
</Target>
</Project>
Save the project file and then apply the transformation, running the following command:
msbuild trans.proj /t:Demo
Where trans.proj is the name of the project file and Demo is the name of task target.

I think it's worth to mention that you can also use with PowerShell the DLL that Visual Studio is using: Microsoft.Web.XmlTransform.dll
PowerShell script, see: Web.Config transforms outside of Microsoft MSBuild?
To load the DLL instead of copying around, I do like this (so you see where to find this DLL, at least in my scenario at work we had to look-up these locations):
if (Test-Path "C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\Web\Microsoft.Web.XmlTransform.dll") {
Add-Type -LiteralPath "C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\Web\Microsoft.Web.XmlTransform.dll"
} elseif (Test-Path "C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v12.0\Web\Microsoft.Web.XmlTransform.dll") {
Add-Type -LiteralPath "C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v12.0\Web\Microsoft.Web.XmlTransform.dll"
} else {
throw [System.IO.FileNotFoundException] "Microsoft.Web.XmlTransform.dll not found."
}
