When I deploy my project with "Publish as Azure WebJob" using Visual Studio 2013/update 4, I get the error in the title.
Fixed by removing the following markup from the .pubxml file. You must exit/restart VS after removing the markup (or VS will add it back in).
<ItemGroup>
<MSDeployParameterValue Include="$(DeployParameterPrefix)DefaultConnection-Web.config Connection String" />
</ItemGroup>
