Ah I am not a developer so I have no idea what you are saying when you say MSBuild.
It looks a lot like XML so you may be able to play with the ConvertTo-Xml or Export-Clixml CMDLETs to make it work. Otherwise you would have to write your own format function to format table output into this XML Like “MSBuild” format. Sorry I missed that point.
