<!-- This file helps enable Batch Build of configurations that have a mix of .Net Framework and .Net targets. It also allows passing bot checks. It has to be this separate file because the same code if put in csproj files will be overridden by Visual Studio with default settings is has for Batch Build. -->

Since we added BaseIntermediateOutputPath above, adding obj/** to exclude all subfolders under obj. This also resolves the "Duplicated attributes" errors.
