How can we display a “step” inside Visual Studio build process?

<Target Name="PackageBinaries">

    <!-- create the build step -->
    <BuildStep TeamFoundationServerUrl="$(TeamFoundationServerUrl)"
               BuildUri="$(BuildUri)"
               Message="Creating Installer"
               Condition=" '$(IsDesktopBuild)' != 'true' " >
      <Output TaskParameter="Id"
              PropertyName="InstallerStepId" />
    </BuildStep>

    <!-- Create the MSI file using WiX -->
    <MSBuild Projects="$(SolutionRoot)SetupProjectwallboard.wixproj"
  Properties="BinariesSource=$(OutDir);PublishDir=$(BinariesRoot);Configuration=%(ConfigurationToBuild.FlavourToBuild)" >
    </MSBuild>

    <!-- If we sucessfully built the installer, tell TFS -->
    <BuildStep TeamFoundationServerUrl="$(TeamFoundationServerUrl)"
               BuildUri="$(BuildUri)"
               Id="$(InstallerStepId)"
               Status="Succeeded"
               Condition=" '$(IsDesktopBuild)' != 'true' " />

    <!-- Note that the condition above means that we do not talk to TFS when doing a Desktop Build -->

    <!-- If we error during this step, then tell TFS we failed-->
    <OnError   ExecuteTargets="MarkInstallerFailed" />
  </Target>

  <Target Name="MarkInstallerFailed">
    <!-- Called by the PackageBinaries method if creating the installer fails -->
    <BuildStep TeamFoundationServerUrl="$(TeamFoundationServerUrl)"
               BuildUri="$(BuildUri)"
               Id="$(InstallerStepId)"
               Status="Failed"
               Condition=" '$(IsDesktopBuild)' != 'true' " />
  </Target>
