Web Deploy Error: "virtual directory not being configured as an application in IIS"

Hi all,

I am trying to use Visual Studio Publish on my Dev machine to deploy a Web Site to a separate IIS Test Server using Web Deploy and I am getting the following error which I do not understand:

Error  It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level.  This error can be caused by a virtual directory not being configured as an application in IIS. TeraTastic D:\Clancy\A_TeraTastic\Dev\TT15\TeraTastic\obj\Debug\AspnetCompileMerge\Source\app_data\nugetbackup\20170306-224002\web.config 146 

Below I have listed the offending section of the referenced web.config file with offending line 146 marked with: "<<<<<  ERROR LINE 146 <<<<<<<<"

      <providers>
        <remove name="MySqlSiteMapProvider"/>
      </providers>

Any assistance to understand and resolve this error would be very much appreciated.

Thanks
