Visual Studio Publish, The “PublishTelemetry” Task Could Not Be Loaded

This is a quick post about an issue I recently had in Visual Studio. I couldn’t find any mention of this after Googling so just in case someone has the same issue, here goes:

When I tried to do a publish in Visual Studio (after downgrading enterprise to professional) I got this error:

The “PublishTelemetry” task could not be loaded from the assembly C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\Web\Microsoft.Web.Publishing.Tasks.dll. Confirm that the declaration is correct, that the assembly and all its dependencies are available

After looking in Visual Studio output window I could see the issue was occurring in:

C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\Web\Microsoft.Web.Publishing.targets

In the section I found the ‘PublishTelemetry’ entry and deleted it. Further down in the file I also found the matching which had the same name ‘PublishTelemetry’ and deleted it. Visual Studio worked again

    I ran across this issue and resolved it by installing Install-Package MSBuild.Microsoft.VisualStudio.Web.targets in the Package Manager Console.
