Delphi – Running Delphi builds under TFS MSBuild

Wanting to build and test a bunch of Borland Delphi 6 projects that are integrated with ASP.NET services. Had been using WANT and CruiseControl for building Delphi. With TFS Build agent we can tie all together and do some testing. I am looking for guidance and direction.

One issue I see is that there is no "solution" in a Delphi project to be given to MSBuild as a '<'SolutionToBuild'>'.

<SolutionToBuild Include="There is no such thing as a Delphi.sln">
    <Targets></Targets>
    <Properties></Properties>
</SolutionToBuild>

Also, I have references to <UsingTask> but am a little unsure how to use them. The <UsingTask> allows run custom task for Delphi command-line compile.

Your guidance would be appreciated.
