Building rptproj leaves build.obj file

[jrmoreno1]

Is there a parameter or property that can be set that will prevent this file from being left behind once the build is finished? If it’s not necessary for some other purpose, could it just be deleted?

The Microsoft Reporting Services extension has its own target and task implemented, not implemented by msbuild. Its own task saves build results info in build.obj file.
