Has anyone seen this error and know how to fix it?
The \"TransformXml\" task could not be loaded from the assembly C:\\Program Files (x86)\\MSBuild\\M
You need two things to make it work:
1) Install Visual Studio Build Tools (You don't need the whole Visual Studio, only the VS Build Tools) with selected "Web development build tools" option on your build server https://www.visualstudio.com/pl/thank-you-downloading-visual-studio/?sku=BuildTools&rel=15
2) Ensure that path to Microsoft.Web.Publishing.Tasks.dll is correct
