Team Build and ClickOnce

The other day I got a question: How can I deploy an app via ClickOnce using Team Build?

There is not out of box way to do that, but we can do it with a simple workaround:

we should overload the target AfterCompile in TFSBuild.Proj to call MSBuild Task Publish and can pass the PublishDir property:

<Target Name="AfterCompile">
  <MSBuild
  Condition=" '@(SolutionToBuild)'!='' "
  Projects="@(SolutionToBuild)"
  Properties="Configuration=%(ConfigurationToBuild.FlavorToBuild);
    Platform=%(ConfigurationToBuild.PlatformToBuild);
    SkipInvalidConfigurations=true;
    VCBuildOverride=$(MSBuildProjectDirectory)\TFSBuild.vsprops;
    FxCopDir=$(FxCopDir);OutDir=$(OutDir);
    PublishDir=$(OutDir);
    ReferencePath=$(ReferencePath);
    TeamBuildConstants=$(TeamBuildConstants);
    $(CodeAnalysisOption);PublishDir=\\qa1Srv\drops\publishedVers\ "
  Targets="Publish" />
</Target>
