TransformXml task could not be loaded from Microsoft.Web.Publishing.Tasks.dll

Question

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

Answer 1

The correct answer to this is to unload the project in question and then edit the csproj file, look for an entry where they are referencing the 10.0 path and change it to point to 11.0 instead.
