This removes the need to copy-paste code that reads a specific directory in Program.cs. Updated docs/samples and tests. We need a workaround in tests to be able to use a P2P for the library. What I did here is the same trick we do in Razor. - Force everyone to use an MSBuild variable to locate the library - Set that variable in a Directory.Build.props for the normal build - Drop a special Directory.Build.props for testing Updates a bunch of test code to use new helper methods for copying stuff, so we can correctly do this.pull/290/head
